Dialogue: 0,0:00:45.95,0:00:48.46,Default,,0000,0000,0000,,There's even a software called cadnano Dialogue: 0,0:00:48.46,0:00:51.24,Default,,0000,0000,0000,,that allows us to design three-dimensional shapes Dialogue: 0,0:00:51.24,0:00:54.33,Default,,0000,0000,0000,,like nano robots or drug delivery systems Dialogue: 0,0:00:54.33,0:00:58.63,Default,,0000,0000,0000,,and use DNA to self-assemble those functional structures. Dialogue: 0,0:00:58.63,0:01:00.70,Default,,0000,0000,0000,,But if we look at the human scale, Dialogue: 0,0:01:00.70,0:01:03.76,Default,,0000,0000,0000,,there's massive problems that aren't being addressed Dialogue: 0,0:01:03.76,0:01:06.13,Default,,0000,0000,0000,,by those nanoscale technologies.

Dialogue: 0,0:01:14.74,0:01:17.25,Default,,0000,0000,0000,,In infrastructure, let's just take one example. Dialogue: 0,0:01:17.25,0:01:18.73,Default,,0000,0000,0000,,Take piping. Dialogue: 0,0:01:18.73,0:01:22.46,Default,,0000,0000,0000,,In water pipes, we have fixed-capacity water pipes Dialogue: 0,0:01:22.46,0:01:26.92,Default,,0000,0000,0000,,that have fixed flow rates, except for expensive pumps and valves.

Dialogue: 0,0:01:37.72,0:01:41.08,Default,,0000,0000,0000,,So I'd like to propose that we can combine those two worlds, Dialogue: 0,0:01:41.08,0:01:46.26,Default,,0000,0000,0000,,that we can combine the world of the nanoscale programmable adaptive materials Dialogue: 0,0:01:46.26,0:01:47.93,Default,,0000,0000,0000,,and the built environment. Dialogue: 0,0:01:47.93,0:01:50.12,Default,,0000,0000,0000,,And I don't mean automated machines.

Dialogue: 0,0:01:52.58,0:01:56.46,Default,,0000,0000,0000,,But I mean programmable materials that build themselves. Dialogue: 0,0:01:56.46,0:01:58.52,Default,,0000,0000,0000,,And that's called self-assembly, Dialogue: 0,0:01:58.52,0:02:03.03,Default,,0000,0000,0000,,which is a process by which disordered parts build an ordered structure Dialogue: 0,0:02:03.03,0:02:05.53,Default,,0000,0000,0000,,through only local interaction. Dialogue: 0,0:02:05.53,0:02:08.70,Default,,0000,0000,0000,,So what do we need if we want to do this at the human scale? Dialogue: 0,0:02:08.70,0:02:10.68,Default,,0000,0000,0000,,We need a few simple ingredients. Dialogue: 0,0:02:10.68,0:02:13.52,Default,,0000,0000,0000,,The first ingredient is materials and geometry, Dialogue: 0,0:02:13.52,0:02:16.98,Default,,0000,0000,0000,,and that needs to be tightly coupled with the energy source. Dialogue: 0,0:02:16.98,0:02:18.64,Default,,0000,0000,0000,,And you can use passive energy -- Dialogue: 0,0:02:18.64,0:02:23.33,Default,,0000,0000,0000,,so heat, shaking, pneumatics, gravity, magnetics. Dialogue: 0,0:02:23.33,0:02:26.40,Default,,0000,0000,0000,,And then you need smartly designed interactions. Dialogue: 0,0:02:26.40,0:02:28.54,Default,,0000,0000,0000,,And those interactions allow for error correction, Dialogue: 0,0:02:28.54,0:02:32.54,Default,,0000,0000,0000,,and they allow the shapes to go from one state to another state. Dialogue: 0,0:02:32.54,0:02:35.77,Default,,0000,0000,0000,,So now I'm going to show you a number of projects that we've built, Dialogue: 0,0:02:35.77,0:02:39.05,Default,,0000,0000,0000,,from one-dimensional, two-dimensional, three-dimensional Dialogue: 0,0:02:39.05,0:02:42.12,Default,,0000,0000,0000,,and even four-dimensional systems. Dialogue: 0,0:02:42.12,0:02:44.00,Default,,0000,0000,0000,,So in one-dimensional systems -- Dialogue: 0,0:02:44.00,0:02:46.91,Default,,0000,0000,0000,,this is a project called the self-folding proteins. Dialogue: 0,0:02:46.91,0:02:51.62,Default,,0000,0000,0000,,And the idea is that you take the three-dimensional structure of a protein -- Dialogue: 0,0:02:51.62,0:02:54.30,Default,,0000,0000,0000,,in this case it's the crambin protein -- Dialogue: 0,0:02:54.30,0:02:57.94,Default,,0000,0000,0000,,you take the backbone -- so no cross-linking, no environmental interactions -- Dialogue: 0,0:02:57.94,0:03:01.10,Default,,0000,0000,0000,,and you break that down into a series of components. Dialogue: 0,0:03:01.10,0:03:03.37,Default,,0000,0000,0000,,And then we embed elastic. Dialogue: 0,0:03:03.37,0:03:05.71,Default,,0000,0000,0000,,And when I throw this up into the air and catch it, Dialogue: 0,0:03:05.71,0:03:10.56,Default,,0000,0000,0000,,it has the full three-dimensional structure of the protein, all of the intricacies. Dialogue: 0,0:03:10.56,0:03:12.66,Default,,0000,0000,0000,,And this gives us a tangible model Dialogue: 0,0:03:12.66,0:03:16.40,Default,,0000,0000,0000,,of the three-dimensional protein and how it folds Dialogue: 0,0:03:16.40,0:03:18.68,Default,,0000,0000,0000,,and all of the intricacies of the geometry. Dialogue: 0,0:03:18.68,0:03:22.13,Default,,0000,0000,0000,,So we can study this as a physical, intuitive model. Dialogue: 0,0:03:22.13,0:03:24.93,Default,,0000,0000,0000,,And we're also translating that into two-dimensional systems -- Dialogue: 0,0:03:24.93,0:03:29.23,Default,,0000,0000,0000,,so flat sheets that can self-fold into three-dimensional structures. Dialogue: 0,0:03:29.23,0:03:33.68,Default,,0000,0000,0000,,In three dimensions, we did a project last year at TEDGlobal Dialogue: 0,0:03:33.68,0:03:35.65,Default,,0000,0000,0000,,with Autodesk and Arthur Olson Dialogue: 0,0:03:35.65,0:03:37.34,Default,,0000,0000,0000,,where we looked at autonomous parts -- Dialogue: 0,0:03:37.34,0:03:41.66,Default,,0000,0000,0000,,so individual parts not pre-connected that can come together on their own. Dialogue: 0,0:03:41.66,0:03:44.43,Default,,0000,0000,0000,,And we built 500 of these glass beakers. Dialogue: 0,0:03:44.43,0:03:46.90,Default,,0000,0000,0000,,They had different molecular structures inside Dialogue: 0,0:03:46.90,0:03:49.12,Default,,0000,0000,0000,,and different colors that could be mixed and matched. Dialogue: 0,0:03:49.12,0:03:51.37,Default,,0000,0000,0000,,And we gave them away to all the TEDsters. Dialogue: 0,0:03:51.37,0:03:53.87,Default,,0000,0000,0000,,And so these became intuitive models Dialogue: 0,0:03:53.87,0:03:57.36,Default,,0000,0000,0000,,to understand how molecular self-assembly works at the human scale. Dialogue: 0,0:03:57.36,0:03:59.18,Default,,0000,0000,0000,,This is the polio virus. Dialogue: 0,0:03:59.18,0:04:01.11,Default,,0000,0000,0000,,You shake it hard and it breaks apart. Dialogue: 0,0:04:01.11,0:04:02.56,Default,,0000,0000,0000,,And then you shake it randomly Dialogue: 0,0:04:02.56,0:04:06.06,Default,,0000,0000,0000,,and it starts to error correct and built the structure on its own. Dialogue: 0,0:04:06.06,0:04:09.03,Default,,0000,0000,0000,,And this is demonstrating that through random energy, Dialogue: 0,0:04:09.03,0:04:13.66,Default,,0000,0000,0000,,we can build non-random shapes. Dialogue: 0,0:04:13.66,0:04:17.18,Default,,0000,0000,0000,,We even demonstrated that we can do this at a much larger scale. Dialogue: 0,0:04:17.18,0:04:19.33,Default,,0000,0000,0000,,Last year at TED Long Beach, Dialogue: 0,0:04:19.33,0:04:22.54,Default,,0000,0000,0000,,we built an installation that builds installations. Dialogue: 0,0:04:22.54,0:04:26.08,Default,,0000,0000,0000,,The idea was, could we self-assemble furniture-scale objects? Dialogue: 0,0:04:26.08,0:04:28.58,Default,,0000,0000,0000,,So we built a large rotating chamber, Dialogue: 0,0:04:28.58,0:04:31.80,Default,,0000,0000,0000,,and people would come up and spin the chamber faster or slower, Dialogue: 0,0:04:31.80,0:04:33.38,Default,,0000,0000,0000,,adding energy to the system Dialogue: 0,0:04:33.38,0:04:36.83,Default,,0000,0000,0000,,and getting an intuitive understanding of how self-assembly works Dialogue: 0,0:04:36.83,0:04:38.21,Default,,0000,0000,0000,,and how we could use this Dialogue: 0,0:04:38.21,0:04:42.95,Default,,0000,0000,0000,,as a macroscale construction or manufacturing technique for products. Dialogue: 0,0:04:42.95,0:04:44.62,Default,,0000,0000,0000,,So remember, I said 4D. Dialogue: 0,0:04:44.62,0:04:48.31,Default,,0000,0000,0000,,So today for the first time, we're unveiling a new project, Dialogue: 0,0:04:48.31,0:04:50.20,Default,,0000,0000,0000,,which is a collaboration with Stratasys, Dialogue: 0,0:04:50.20,0:04:52.04,Default,,0000,0000,0000,,and it's called 4D printing. Dialogue: 0,0:04:52.04,0:04:53.100,Default,,0000,0000,0000,,The idea behind 4D printing Dialogue: 0,0:04:53.100,0:04:56.100,Default,,0000,0000,0000,,is that you take multi-material 3D printing -- Dialogue: 0,0:04:56.100,0:04:59.18,Default,,0000,0000,0000,,so you can deposit multiple materials -- Dialogue: 0,0:04:59.18,0:05:01.07,Default,,0000,0000,0000,,and you add a new capability, Dialogue: 0,0:05:01.07,0:05:02.93,Default,,0000,0000,0000,,which is transformation, Dialogue: 0,0:05:02.93,0:05:04.25,Default,,0000,0000,0000,,that right off the bed, Dialogue: 0,0:05:04.25,0:05:08.58,Default,,0000,0000,0000,,the parts can transform from one shape to another shape directly on their own. Dialogue: 0,0:05:08.58,0:05:12.08,Default,,0000,0000,0000,,And this is like robotics without wires or motors. Dialogue: 0,0:05:12.08,0:05:13.73,Default,,0000,0000,0000,,So you completely print this part, Dialogue: 0,0:05:13.73,0:05:16.53,Default,,0000,0000,0000,,and it can transform into something else. Dialogue: 0,0:05:16.53,0:05:21.49,Default,,0000,0000,0000,,We also worked with Autodesk on a software they're developing called Project Cyborg. Dialogue: 0,0:05:21.49,0:05:24.62,Default,,0000,0000,0000,,And this allows us to simulate this self-assembly behavior Dialogue: 0,0:05:24.62,0:05:27.82,Default,,0000,0000,0000,,and try to optimize which parts are folding when. Dialogue: 0,0:05:27.82,0:05:30.55,Default,,0000,0000,0000,,But most importantly, we can use this same software Dialogue: 0,0:05:30.55,0:05:33.46,Default,,0000,0000,0000,,for the design of nanoscale self-assembly systems Dialogue: 0,0:05:33.46,0:05:36.30,Default,,0000,0000,0000,,and human scale self-assembly systems. Dialogue: 0,0:05:36.30,0:05:39.81,Default,,0000,0000,0000,,These are parts being printed with multi-material properties. Dialogue: 0,0:05:39.81,0:05:41.53,Default,,0000,0000,0000,,Here's the first demonstration. Dialogue: 0,0:05:41.53,0:05:43.43,Default,,0000,0000,0000,,A single strand dipped in water Dialogue: 0,0:05:43.43,0:05:45.78,Default,,0000,0000,0000,,that completely self-folds on its own Dialogue: 0,0:05:45.78,0:05:49.70,Default,,0000,0000,0000,,into the letters M I T. Dialogue: 0,0:05:49.70,0:05:51.52,Default,,0000,0000,0000,,I'm biased. Dialogue: 0,0:05:51.52,0:05:54.97,Default,,0000,0000,0000,,This is another part, single strand, dipped in a bigger tank Dialogue: 0,0:05:54.97,0:05:59.60,Default,,0000,0000,0000,,that self-folds into a cube, a three-dimensional structure, on its own. Dialogue: 0,0:05:59.60,0:06:01.45,Default,,0000,0000,0000,,So no human interaction. Dialogue: 0,0:06:01.45,0:06:03.34,Default,,0000,0000,0000,,And we think this is the first time Dialogue: 0,0:06:03.34,0:06:05.58,Default,,0000,0000,0000,,that a program and transformation Dialogue: 0,0:06:05.58,0:06:08.83,Default,,0000,0000,0000,,has been embedded directly into the materials themselves. Dialogue: 0,0:06:08.83,0:06:11.56,Default,,0000,0000,0000,,And it also might just be the manufacturing technique Dialogue: 0,0:06:11.56,0:06:15.70,Default,,0000,0000,0000,,that allows us to produce more adaptive infrastructure in the future. Dialogue: 0,0:06:15.70,0:06:16.88,Default,,0000,0000,0000,,So I know you're probably thinking, Dialogue: 0,0:06:16.88,0:06:21.11,Default,,0000,0000,0000,,okay, that's cool, but how do we use any of this stuff for the built environment? Dialogue: 0,0:06:21.11,0:06:23.37,Default,,0000,0000,0000,,So I've started a lab at MIT, Dialogue: 0,0:06:23.37,0:06:25.25,Default,,0000,0000,0000,,and it's called the Self-Assembly Lab.
