Biomimetic Pressure Sensors Guide Underwater Vehicles

'Lateral lines' in fish contain hundreds of tiny pressure and velocity sensors that enable them to navigate through currents and eddies as efficiently as possible. To mimic that ability, MIT researchers have developed sensitive, MEMS-based pressure sensors and mounted them on a small...

Stay Tuned: Antennas May Increase Solar Panel Efficiency

Solar-powered energy collected by panels made of silicone is limited — contemporary panel technology can only convert approximately seven percent of optical solar waves into electric current. Researchers at Tel Aviv University are now working to develop a more efficient solar panel...

Helping Underwater Robots Gain a Better Grip

Underwater vehicles have become good at using propellers and thrusters to stay in one place, even in strong currents. But holding on to a surface while exerting force to do a job has been a challenge. Now, MIT researchers are tackling this issue by designing a “controllable adhesion system” that...
