WEBVTT 00:00:01.723 --> 00:00:03.111 Please meet Jane. 00:00:03.644 --> 00:00:05.639 She has a high-risk pregnancy. 00:00:05.663 --> 00:00:07.420 Within 24 weeks, 00:00:07.444 --> 00:00:09.605 she's on bed rest at the hospital, 00:00:09.629 --> 00:00:12.456 being monitored for her preterm contractions. NOTE Paragraph 00:00:13.024 --> 00:00:14.918 She doesn't look the happiest. 00:00:14.942 --> 00:00:18.163 That's in part because it requires technicians and experts 00:00:18.187 --> 00:00:22.502 to apply these clunky belts on her to monitor her uterine contractions. 00:00:23.550 --> 00:00:28.290 Another reason Jane is not so happy is because she's worried. 00:00:28.768 --> 00:00:31.394 In particular, she's worried about what happens 00:00:31.418 --> 00:00:34.823 after her 10-day stay on bed rest at the hospital. 00:00:35.438 --> 00:00:37.508 What happens when she's home? 00:00:37.532 --> 00:00:41.261 If she were to give birth this early it would be devastating. 00:00:41.874 --> 00:00:43.628 As an African-American woman, 00:00:43.652 --> 00:00:46.734 she's twice as likely to have a premature birth 00:00:47.376 --> 00:00:48.949 or to have a stillbirth. 00:00:49.551 --> 00:00:52.529 So Jane basically has one of two options: 00:00:52.553 --> 00:00:54.578 stay at the hospital on bed rest, 00:00:55.237 --> 00:00:58.695 a prisoner to the technology until she gives birth, 00:00:59.469 --> 00:01:02.409 and then spend the rest of her life paying for the bill; 00:01:02.946 --> 00:01:07.554 or head home after her 10-day stay and hope for the best. 00:01:08.198 --> 00:01:11.293 Neither of these two options seems appealing. NOTE Paragraph 00:01:12.132 --> 00:01:14.243 As I began to think about stories like this 00:01:14.267 --> 00:01:16.053 and hear about stories like this, 00:01:16.077 --> 00:01:18.170 I began to ask myself and imagine: 00:01:18.194 --> 00:01:19.736 Is there an alternative? 00:01:19.760 --> 00:01:24.496 Is there a way we could have the benefits of high-fidelity monitoring 00:01:24.520 --> 00:01:27.319 that we get with our trusted partners in the hospital 00:01:27.343 --> 00:01:29.702 while someone is at home living their daily life? NOTE Paragraph 00:01:30.832 --> 00:01:32.327 With that in mind, 00:01:32.351 --> 00:01:34.298 I encouraged people in my research group 00:01:34.322 --> 00:01:37.830 to partner with some clever material scientists, 00:01:37.854 --> 00:01:40.261 and all of us came together and brainstormed. 00:01:40.904 --> 00:01:42.345 And after a long process, 00:01:42.369 --> 00:01:44.763 we came up with a vision, an idea, 00:01:44.787 --> 00:01:48.565 of a wearable system that perhaps you could wear like a piece of jewelry 00:01:48.589 --> 00:01:51.045 or you could apply to yourself like a Band-Aid. 00:01:51.463 --> 00:01:55.646 And after many trials and tribulations and years of endeavors, 00:01:55.670 --> 00:01:59.397 we were able to come up with this flexible electronic patch 00:01:59.421 --> 00:02:01.816 that was manufactured using the same processes 00:02:01.840 --> 00:02:04.521 that they use to build computer chips, 00:02:04.545 --> 00:02:08.977 except the electronics are transferred from a semiconductor wafer 00:02:09.001 --> 00:02:13.269 onto a flexible material that can interface with the human body. NOTE Paragraph 00:02:13.775 --> 00:02:16.823 These systems are about the thickness of a human hair. 00:02:18.006 --> 00:02:21.259 They can measure the types of information that we want, 00:02:21.948 --> 00:02:23.127 things such as: 00:02:23.151 --> 00:02:24.324 bodily movement, 00:02:24.670 --> 00:02:26.074 bodily temperature, 00:02:26.098 --> 00:02:27.903 electrical rhythms of the body 00:02:27.927 --> 00:02:29.085 and so forth. 00:02:29.403 --> 00:02:31.377 We can also engineer these systems, 00:02:31.883 --> 00:02:34.291 so they can integrate energy sources, 00:02:34.877 --> 00:02:37.842 and can have wireless transmission capabilities. NOTE Paragraph 00:02:38.624 --> 00:02:42.529 So as we began to build these types of systems, 00:02:42.553 --> 00:02:46.891 we began to test them on ourselves in our research group. 00:02:46.915 --> 00:02:50.279 But in addition, we began to reach out to some of our clinical partners 00:02:50.303 --> 00:02:51.458 in San Diego, 00:02:51.482 --> 00:02:55.182 and test these on different patients in different clinical conditions, 00:02:55.206 --> 00:02:57.903 including moms-to-be like Jane. NOTE Paragraph 00:02:58.531 --> 00:03:03.511 Here is a picture of a pregnant woman in labor at our university hospital 00:03:03.535 --> 00:03:08.466 being monitored for her uterine contractions with the conventional belt. 00:03:08.939 --> 00:03:10.090 In addition, 00:03:10.114 --> 00:03:12.706 our flexible electronic patches are there. 00:03:13.268 --> 00:03:17.544 This picture demonstrates waveforms pertaining to the fetal heart rate, 00:03:17.568 --> 00:03:20.485 where the red corresponds to what was acquired 00:03:20.509 --> 00:03:22.088 with the conventional belts, 00:03:22.112 --> 00:03:24.770 and the blue corresponds to our estimates 00:03:24.794 --> 00:03:28.482 using our flexible electronic systems and our algorithms. NOTE Paragraph 00:03:28.932 --> 00:03:30.380 At this moment, 00:03:30.404 --> 00:03:33.022 we gave ourselves a big mental high five. 00:03:33.508 --> 00:03:36.915 Some of the things we had imagined were beginning to come to fruition, 00:03:36.939 --> 00:03:39.616 and we were actually seeing this in a clinical context. NOTE Paragraph 00:03:40.083 --> 00:03:41.523 But there was still a problem. 00:03:41.974 --> 00:03:45.335 The problem was, the way we manufactured these systems 00:03:45.359 --> 00:03:46.816 was very inefficient, 00:03:46.840 --> 00:03:47.997 had low yield 00:03:48.021 --> 00:03:49.365 and was very error-prone. 00:03:50.105 --> 00:03:51.256 In addition, 00:03:51.280 --> 00:03:53.752 as we talked to some of the nurses in the hospital, 00:03:53.776 --> 00:03:55.966 they encouraged us to make sure 00:03:55.990 --> 00:04:00.003 that our electronics worked with typical medical adhesives 00:04:00.027 --> 00:04:01.484 that are used in a hospital. 00:04:02.217 --> 00:04:04.431 We had an epiphany and said, "Wait a minute. 00:04:04.998 --> 00:04:07.669 Rather than just making them work with adhesives, 00:04:07.693 --> 00:04:10.721 let's integrate them into adhesives, 00:04:11.194 --> 00:04:13.697 and that could solve our manufacturing problem." NOTE Paragraph 00:04:14.269 --> 00:04:16.260 This picture that you see here 00:04:16.284 --> 00:04:20.779 is our ability to embed these censors inside of a piece of Scotch tape 00:04:20.803 --> 00:04:23.519 by simply peeling it off of a wafer. 00:04:24.255 --> 00:04:27.624 Ongoing work in our research group allows us to, in addition, 00:04:27.648 --> 00:04:31.357 embed integrated circuits into the flexible adhesives 00:04:31.381 --> 00:04:35.071 to do things like amplifying signals and digitizing them, 00:04:35.095 --> 00:04:36.273 processing them 00:04:36.297 --> 00:04:38.560 and encoding for wireless transmission. 00:04:39.113 --> 00:04:43.015 All of this integrated into the same medical adhesives 00:04:43.039 --> 00:04:44.849 that are used in the hospital. NOTE Paragraph 00:04:45.810 --> 00:04:47.302 So when we reached this point, 00:04:47.326 --> 00:04:49.750 we had some other challenges, 00:04:49.774 --> 00:04:53.089 from both an engineering as well as a usability perspective, 00:04:53.113 --> 00:04:55.936 to make sure that we could make it used practically. NOTE Paragraph 00:04:57.207 --> 00:04:59.694 In many digital health discussions, 00:04:59.718 --> 00:05:04.665 people believe in and embrace the idea that we can simply digitize the data, 00:05:04.689 --> 00:05:06.269 wirelessly transmit it, 00:05:06.293 --> 00:05:07.767 send it to the cloud, 00:05:07.791 --> 00:05:08.988 and in the cloud, 00:05:09.012 --> 00:05:11.745 we can extract meaningful information for interpretation. 00:05:12.147 --> 00:05:14.624 And indeed, you can do all of that, 00:05:14.648 --> 00:05:17.637 if you're not worried about some of the energy challenges. 00:05:17.661 --> 00:05:19.324 Think about Jane for a moment. 00:05:19.348 --> 00:05:21.152 She doesn't live in Palo Alto, 00:05:21.176 --> 00:05:22.889 nor does she live in Beverly Hills. 00:05:23.359 --> 00:05:24.517 What that means is, 00:05:24.541 --> 00:05:27.871 we have to be mindful about her data plan and how much it would cost 00:05:27.895 --> 00:05:31.514 for her to be sending out a continuous stream of data. NOTE Paragraph 00:05:32.383 --> 00:05:33.662 There's another challenge 00:05:33.686 --> 00:05:37.384 that not everyone in the medical profession is comfortable talking about. 00:05:37.408 --> 00:05:40.236 And that is, that Jane does not have the most trust 00:05:40.260 --> 00:05:41.745 in the medical establishment. 00:05:42.460 --> 00:05:47.599 She, people like her, her ancestors, have not had the best experiences 00:05:47.623 --> 00:05:50.619 at the hands of doctors and the hospital 00:05:51.163 --> 00:05:52.551 or insurance companies. 00:05:53.466 --> 00:05:56.807 That means that we have to be mindful of questions of privacy. 00:05:56.831 --> 00:05:58.452 Jane might not feel that happy 00:05:58.476 --> 00:06:01.755 about all that data being processed into the cloud. 00:06:02.712 --> 00:06:04.708 And Jane cannot be fooled; 00:06:05.346 --> 00:06:06.830 she reads the news. 00:06:06.854 --> 00:06:09.824 She knows that if the federal government can be hacked, 00:06:09.848 --> 00:06:11.849 if the Fortune 500 can be hacked, 00:06:12.409 --> 00:06:13.920 so can her doctor. NOTE Paragraph 00:06:15.014 --> 00:06:16.749 And so with that in mind, 00:06:16.773 --> 00:06:17.969 we had an epiphany. 00:06:18.858 --> 00:06:21.588 We cannot outsmart all the hackers in the world, 00:06:21.612 --> 00:06:24.379 but perhaps we can present them a smaller target. 00:06:24.986 --> 00:06:27.167 What if we could actually, 00:06:27.191 --> 00:06:31.123 rather than have those algorithms that do data interpretation 00:06:31.147 --> 00:06:32.360 run in the cloud, 00:06:32.904 --> 00:06:36.315 what if we have those algorithms run on those small integrated circuits 00:06:36.339 --> 00:06:38.419 embedded into those adhesives? NOTE Paragraph 00:06:38.995 --> 00:06:42.089 And so when we integrate these things together, 00:06:42.113 --> 00:06:45.617 what this means is that now we can think about the future 00:06:45.641 --> 00:06:49.706 where someone like Jane can still go about living her normal daily life, 00:06:49.730 --> 00:06:51.202 she can be monitored, 00:06:51.226 --> 00:06:54.726 it can be done in a way where she doesn't have to get another job 00:06:54.750 --> 00:06:56.215 to pay her data plan, 00:06:56.239 --> 00:06:59.934 and we can also address some of her concerns about privacy. NOTE Paragraph 00:07:00.907 --> 00:07:02.057 So at this point, 00:07:02.081 --> 00:07:04.085 we're feeling very good about ourselves. 00:07:04.109 --> 00:07:05.272 We've accomplished this, 00:07:05.296 --> 00:07:08.466 we've begun to address some of these questions about privacy 00:07:08.490 --> 00:07:12.381 and we feel like, pretty much the chapter is closed now. 00:07:12.405 --> 00:07:15.079 Everyone lived happily ever after, right? 00:07:16.751 --> 00:07:18.314 Well, not so fast. NOTE Paragraph 00:07:18.338 --> 00:07:19.543 (Laughter) NOTE Paragraph 00:07:19.567 --> 00:07:22.607 One of the things we have to remember, as I mentioned earlier, 00:07:22.631 --> 00:07:26.012 is that Jane does not have the most trust in the medical establishment. 00:07:26.036 --> 00:07:27.199 We have to remember 00:07:27.223 --> 00:07:30.737 that there are increasing and widening health disparities, 00:07:30.761 --> 00:07:34.065 and there's inequity in terms of proper care management. 00:07:34.616 --> 00:07:37.110 And so what that means is that this simple picture 00:07:37.134 --> 00:07:38.779 of Jane and her data -- 00:07:38.803 --> 00:07:42.730 even with her being comfortable being wirelessly transmitted to the cloud, 00:07:42.754 --> 00:07:45.069 letting a doctor intervene if necessary -- 00:07:45.093 --> 00:07:46.559 is not the whole story. NOTE Paragraph 00:07:47.091 --> 00:07:48.485 So what we're beginning to do 00:07:48.509 --> 00:07:53.336 is to think about ways to have trusted parties serve as intermediaries 00:07:53.360 --> 00:07:56.778 between people like Jane and her health care providers. 00:07:56.802 --> 00:07:59.813 For example, we've begun to partner with churches 00:07:59.837 --> 00:08:02.694 and to think about nurses that are church members, 00:08:02.718 --> 00:08:04.740 that come from that trusted community, 00:08:04.764 --> 00:08:08.687 as patient advocates and health coaches to people like Jane. NOTE Paragraph 00:08:09.462 --> 00:08:11.469 Another thing we have going for us 00:08:11.493 --> 00:08:13.529 is that insurance companies, increasingly, 00:08:13.553 --> 00:08:15.511 are attracted to some of these ideas. 00:08:15.906 --> 00:08:17.613 They're increasingly realizing 00:08:17.637 --> 00:08:20.577 that perhaps it's better to pay one dollar now 00:08:20.601 --> 00:08:23.584 for a wearable device and a health coach, 00:08:23.608 --> 00:08:25.774 rather than paying 10 dollars later, 00:08:26.253 --> 00:08:28.807 when that baby is born prematurely 00:08:28.831 --> 00:08:31.772 and ends up in the neonatal intensive care unit -- 00:08:31.796 --> 00:08:34.691 one of the most expensive parts of a hospital. NOTE Paragraph 00:08:35.697 --> 00:08:38.118 This has been a long learning process for us. 00:08:38.593 --> 00:08:42.428 This iterative process of breaking through and attacking one problem 00:08:42.452 --> 00:08:44.223 and not feeling totally comfortable, 00:08:44.247 --> 00:08:46.066 and identifying the next problem, 00:08:46.090 --> 00:08:48.147 has helped us go along this path 00:08:48.171 --> 00:08:51.247 of actually trying to not only innovate with this technology 00:08:51.271 --> 00:08:55.223 but make sure it can be used for people who perhaps need it the most. NOTE Paragraph 00:08:55.709 --> 00:08:58.493 Another learning lesson we've taken from this process 00:08:58.517 --> 00:08:59.896 that is very humbling, 00:08:59.920 --> 00:09:04.247 is that as technology progresses and advances at an accelerating rate, 00:09:04.271 --> 00:09:08.213 we have to remember that human beings are using this technology, 00:09:08.237 --> 00:09:09.839 and we have to be mindful 00:09:09.863 --> 00:09:13.303 that these human beings -- they have a face, 00:09:13.327 --> 00:09:14.589 they have a name 00:09:14.613 --> 00:09:15.774 and a life. 00:09:15.798 --> 00:09:17.409 And in the case of Jane, 00:09:17.433 --> 00:09:18.889 hopefully, two. NOTE Paragraph 00:09:20.041 --> 00:09:21.235 Thank you. NOTE Paragraph 00:09:21.259 --> 00:09:26.497 (Applause)
