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

How squid ink could make going to the dentist painless

Squid ink could be used as a new imaging method at the dentist to check for gum disease, according to new research from the University of California at San Diego. Combining squid ink with light and ultrasound, engineers at UCSD have created a new dental imaging method that can painlessly and non-invasively examine a patient’s

Could this temperature sensor reduce power consumption in medical devices?

A new temperature sensor that runs at 113 pW could make wearables and even implantable medical devices less power dependent, according to research from the University of California at San Diego. The temperature sensor, developed by electrical engineers at UCSD, uses about 628 times lower power than state-of-the-art power sources and is 10 billion times

This retinal prosthetic could restore sight in blind people

University of California San Diego engineers have collaborated with the startup company Nanovision Biosciences to create nanotechnology and wireless electronics that can be used as a retinal prosthesis. The prosthesis is designed to help restore the ability of retinal neurons to respond to light. This is not the first example of prosthetic retinas. Current retinal
