Standalone sweat sensor provides immediate readout

Engineers at the University of California San Diego have developed a thin, flexible and stretchy sweat sensor that can show the level of glucose, lactate, sodium, or pH of your sweat, at the press of a finger. It is the first ...

A new wearable technology—for plants

Plants can't speak up when they are thirsty. And visual signs, such as shriveling or browning leaves, don't start until most of their water is gone. To detect water loss earlier, researchers reporting in ACS Applied Materials ...

Folding design leads to heart sensor with smaller profile

As advances in wearable devices push the amount of information they can provide consumers, sensors increasingly have to conform to the contours of the body. One approach applies the principles of kirigami to give sensors ...
