Stretchable, Stick-on Electronic Patches for Wireless Health Monitoring
| video (1:06) | 590 views
University of Illinois and Northwestern University engineers have developed thin stick-on patches that stretch and move with the skin and incorporate commercial chip-based electronics for wireless health monitoring. The patch is constructed of a thin elastic envelope filled with fluid. The chip components are suspended on tiny raised support points, bonding them to the underlying patch but allowing the patch to bend. Tiny wires that connect the electronics components – radios, power...
X-Ray Vision Robots Can See Through Walls Using Only WiFi
| video | 1,501 views
University of California Santa Barbara researchers have demonstrated a system for two unmanned vehicles to see through thick concrete walls using only WiFi signals - fully discovering what is on the other side with high accuracy. The objects on the other side don’t have to move to be detected. Potential applications include search and rescue operations and surveillance. One robot measures the wireless transmissions of the other robot that is in the broadcast mode. Each wireless transmission...
NaNose: Handheld ‘Nano-Artificial Nose’ Detects Cancer Non-Invasively
| video (1:58) | 654 views
Chemical engineer Hossam Haick of the Technion-Israel Institute of Technology is the inventor of a ‘nano-artificial nose’ that can detect cancer and kidney disease. The 'NaNose' electronic device detects disease biomarkers passing from the bloodstream to the lungs and out through the breath. It has proven effective in distinguishing between lung, prostate, breast, and colorectal cancer.
Computer Simulations Show Offshore Wind Turbine Farms Could Curb Hurricanes
| video (2:05) | 1,080 views
Computer simulations by Stanford University professor Mark Z. Jacobson have shown that offshore wind farms with thousands of wind turbines could have sapped the power of three real-life hurricanes, significantly decreasing their winds and accompanying storm surge, and possibly preventing billions of dollars in damages. Jacobson found that the wind turbines could disrupt a hurricane enough to reduce peak wind speeds by up to 92 mph and decrease storm surge by up to 79 percent. In the case of...
Advanced, Electroactive Materials-Based Transducer & Actuator
| video | 909 views
Researchers at the NASA Langley Research Center produced an advanced, electroactive materials-based transducer that can harvest orders of magnitude more energy in a given application than traditional solutions. Langley researchers also developed a hybrid actuator with both an electroactive polymer and an electroactive ceramic that achieves enhanced displacement performance from a single power supply. The actuator reduces electrical consumption while improving mechanical displacement compared...
