-
Please meet Jane.
-
She has a high-risk pregnancy.
-
Within 24 weeks,
-
she's on bed rest at the hospital,
-
being monitored
for her preterm contractions.
-
She doesn't look the happiest.
-
That's in part because it requires
technicians and experts
-
to apply these clunky belts on her
to monitor her uterine contractions.
-
Another reason Jane is not so happy
is because she's worried.
-
In particular, she's worried
about what happens
-
after her 10-day stay
on bed rest at the hospital.
-
What happens when she's home?
-
If she were to give birth this early
it would be devastating.
-
As an African-American woman,
-
she's twice as likely
to have a premature birth
-
or to have a stillbirth.
-
So Jane basically has one of two options:
-
stay at the hospital on bed rest,
-
a prisoner to the technology
until she gives birth,
-
and then spend the rest
of her life paying for the bill;
-
or head home after her 10-day stay
and hope for the best.
-
Neither of these two options
seems appealing.
-
As I began to think
about stories like this
-
and hear about stories like this,
-
I began to ask myself and imagine:
-
Is there an alternative?
-
Is there a way we could have
the benefits of high-fidelity monitoring
-
that we get with our trusted
partners in the hospital
-
while someone is at home
living their daily life?
-
With that in mind,
-
I encouraged people in my research group
-
to partner with some
clever material scientists,
-
and all of us came together
and brainstormed.
-
And after a long process,
-
we came up with a vision, an idea,
-
of a wearable system that perhaps
you could wear like a piece of jewelry
-
or you could apply
to yourself like a Band-Aid.
-
And after many trials and tribulations
and years of endeavors,
-
we were able to come up
with this flexible electronic patch
-
that was manufactured
using the same processes
-
that they use to build computer chips,
-
except the electronics are transferred
from a semiconductor wafer
-
onto a flexible material
that can interface with the human body.
-
These systems are about
the thickness of a human hair.
-
It can measure the types
of information that we want,
-
things such as:
-
bodily movement,
-
bodily temperature,
-
electrical rhythms of the body
-
and so forth.
-
We can also engineer these systems,
-
so they can integrate energy sources,
-
and can have wireless
transmission capabilities.
-
So as we began to build
these types of systems,
-
we began to test them on ourselves
in our research group.
-
But in addition, we began to reach out
to some of our clinical partners
-
in San Diego,
-
and test these on different patients
in different clinical conditions,
-
including moms-to-be like Jane.
-
Here is a picture of a pregnant woman
in labor at our university hospital
-
being monitored for her uterine
contractions with the conventional belt.
-
In addition,
-
our flexible electronic patches are there.
-
This picture demonstrates waveforms
pertaining to the fetal heart rate,
-
where the red corresponds
to what was acquired
-
with the conventional belts,
-
and the blue corresponds to our estimates
-
using our flexible electronic systems
and our algorithms.
-
At this moment,
-
we gave ourselves a big mental high five.
-
Some of the things we had imagined
were beginning to come to fruition,
-
and we were actually seeing this
in a clinical context.
-
But there was still a problem.
-
The problem was, the way
we manufactured these systems
-
was very inefficient,
-
had low yield
-
and was very error-prone.
-
In addition,
-
as we talked to some
of the nurses in the hospital,
-
they encouraged us to make sure
-
that our electronics worked
with typical medical adhesives
-
that are used in a hospital.
-
We had an epiphany and said,
"Wait a minute.
-
Rather than just making
them work with adhesives,
-
let's integrate them into adhesives,
-
and that could solve
our manufacturing problem."
-
This picture that you see here
-
is our ability to embed these censors
inside of a piece of Scotch tape
-
by simply peeling it off of a wafer.
-
Ongoing work in our research group
allows us to, in addition,
-
embed integrated circuits
into the flexible adhesives
-
to do things like amplifying signals
and digitizing them,
-
processing them
-
and encoding for wireless transmission.
-
All of this integrated
into the same medical adhesives
-
that are used in the hospital.
-
So when we reached this point,
-
we had some other challenges,
-
from both an engineering
as well as a usability perspective,
-
to make sure that we could
make it used practically.
-
In many digital health discussions,
-
people believe in and embrace the idea
that we can simply digitize the data,
-
wirelessly transmit it,
-
send it to the cloud,
-
and in the cloud,
-
we can extract meaningful
information for interpretation.
-
And indeed, you can do all of that,
-
if you're not worried
about some of the energy challenges.
-
Think about Jane for a moment.
-
She doesn't live in Palo Alto,
-
nor does she live in Beverly Hills.
-
What that means is,
-
we have to be mindful about her data plan
and how much it would cost
-
for her to be sending out
a continuous stream of data.
-
There's another challenge
-
that not everyone in the medical
profession is comfortable talking about.
-
And that is, that Jane
does not have the most trust
-
in the medical establishment.
-
She, people like her, her ancestors,
have not had the best experiences
-
at the hands of doctors and the hospital
-
or insurance companies.
-
That means that we have to be mindful
of questions of privacy.
-
Jane might not feel that happy
-
about all that data
being processed into the cloud.
-
And Jane cannot be fooled;
-
she reads the news.
-
She knows that if the federal
government can be hacked,
-
if the Fortune 500 can be hacked,
-
so can her doctor.
-
And so with that in mind,
-
we had an epiphany.
-
We cannot outsmart
all the hackers in the world,
-
but perhaps we can present
them a smaller target.
-
What if we could actually,
-
rather than have those algorithms
that do data interpretation
-
run in the cloud,
-
what if we have those algorithms run
on those small integrated circuits
-
embedded into those adhesives?
-
And so when we integrate
these things together,
-
what this means is that now
we can think about the future
-
where someone like Jane can still
go about living her normal daily life,
-
she can be monitored,
-
it can be done in a way where
she doesn't have to get another job
-
to pay her data plan,
-
and we can also address
some of her concerns about privacy.
-
So at this point,
-
we're feeling very good about ourselves.
-
We've accomplished this,
-
we've begun to address some
of these questions about privacy
-
and we feel like, pretty much
the chapter is closed now.
-
Everyone lived happily ever after, right?
-
Well, not so fast.
-
(Laughter)
-
One of the things we have to remember,
as I mentioned earlier,
-
is that Jane does not have the most trust
in the medical establishment.
-
We have to remember
-
that there are increasing
and widening health disparities,
-
and there's inequity in terms
of proper care management.
-
And so what that means
is that this simple picture
-
of Jane and her data --
-
even with her being comfortable
being wirelessly transmitted to the cloud,
-
letting a doctor intervene if necessary --
-
is not the whole story.
-
So what we're beginning to do
-
is to think about ways to have
trusted parties serve as intermediaries
-
between people like Jane
and her health care providers.
-
For example, we've begun
to partner with churches
-
and to think about nurses
that are church members,
-
that come from that trusted community,
-
as patient advocates and health coaches
to people like Jane.
-
Another thing we have going for us
-
is that insurance companies, increasingly,
-
are attracted to some of these ideas.
-
They're increasingly realizing
-
that perhaps it's better
to pay one dollar now
-
for a wearable device and a health coach,
-
rather than paying 10 dollars later,
-
when that baby is born prematurely
-
and ends up in the neonatal
intensive care unit --
-
one of the most expensive
parts of a hospital.
-
This has been a long
learning process for us.
-
This iterative process of breaking
through and attacking one problem
-
and not feeling totally comfortable,
-
and identifying the next problem,
-
has helped us go along this path
-
of actually trying to not only
innovate with this technology,
-
but make sure it can be used for people
who perhaps need it the most.
-
Another learning lesson
we've taken from this process
-
that is very humbling,
-
is that as technology progresses
and advances at an accelerating rate,
-
we have to remember that human beings
are using this technology,
-
and we have to be mindful
-
that these human beings --
they have a face,
-
they have a name
-
and a life.
-
And in the case of Jane,
-
hopefully, two.
-
Thank you.
