This sweat-powered biofuel cell could create better wearable devices

Engineers at the University of California at San Diego have created a stretchable sweat-powered biofuel cell, and it could enable better wearables. The biofuel cells use energy from sweat to generate 10 times more power per surface area than other biofuel cells that are used in wearables. The researchers claim it could be used to

This artificial skin can sense temperature changes

Engineers and scientists from the California Institute of Technology (Caltech) and ETH Zurich have developed a temperature detecting artificial skin that could be used for prosthetic limbs in amputees. A team led by Chiara Daraio at Caltech created a material from fabricating synthetic woods in a petri dish; the material has an electrical response to temperature
