Anyone with children knows that while controlling one child can be hard, controlling many at once can be nearly impossible. Getting swarms of robots to work collectively can be equally challenging, unless…
Ultrathin self-powered e-health patches to monitor pulse and blood pressure
Scientists at Osaka University, Japan, in cooperation with JOANNEUM RESEARCH, Austria, introduced wireless health monitoring patches that use embedded piezoelectric nanogenerators to power themselves with harvested biomechanical energy. This work may lead…
Wearable sensors detect gas leaks and show Holographic visual alarms immediately
Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that…
New hydrogel can repair tears in human tissue
EPFL scientists have developed an injectable gel that can attach to various kinds of soft internal tissues and repair tears resulting from an accident or trauma. Our soft tissues can be torn…
Leveraging the 5G network to wirelessly power IoT devices
Researchers at the Georgia Institute of Technology have uncovered an innovative way to tap into the over-capacity of 5G networks, turning them into “a wireless power grid” for powering Internet of Things…
