Dynamic Daylight Control System
In the U.S. alone, commercial and residential buildings account for more than 40 percent of the total energy consumption – mostly for lighting. What’s more, the deep building layouts that are typical in the U.S. have led to a complete reliance on artificial lighting systems that are less desirable than natural daylight. Many of the...
Putting Biofilms to Work
A team at the Wyss Institute sees biofilms as a robust new platform for designer nanomaterials that could treat inflammatory bowel diseases, clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more. A novel protein engineering system called BIND, which stands for Biofilm-Integrated Nanofiber Display, could be the essential ingredient in tomorrow’s probiotic...
Shrilk Biodegradable Plastic
Wyss Institute researchers have developed a fully degradable bioplastic by isolating a material called chitosan found in shrimp shells and forming a laminate with silk fibroin protein that mimics the microarchitecture of natural insect cuticle. The new material, called “Shrilk”, can be used to manufacture objects without the environmental threat posed by conventional synthetic plastics,...
Phase-Separating Liquid Gated Membranes
Just like pores in living organisms that control the absorption and excretion of fluids, gases and solids in response to their environments, flow-gating membranes have proved very useful for many mechanical systems, such as gas and liquid separators, dialysis machines, or open heart bypass pumps. But conventional approaches to create synthetic “gated pores” within those...
SLIPS (Slippery Liquid-Infused Porous Surfaces)
The need for an inexpensive, super-repellent surface cuts across a vast swath of societal sectors—from refrigeration and architecture, to medical devices and consumer products. Most state-of-the-art liquid repellent surfaces designed in the last decade are modeled after lotus leaves, which are extremely hydrophobic due to their rough, waxy surface and the physics of their natural...
Programmable Robot Swarms
Collective behaviors enable animals like ants to build huge complex structures through the distributed actions of millions of independent agents. These collective behaviors are inspiring engineers at the Wyss Institute to build simple mobile robots that harness the demonstrated power of the swarm, performing collective tasks like transporting large objects or autonomously building human-scale structures....
