A "living" smartwatch powered by a slime mold needs food and care to function. Can it make us less fickle consumers of technology?

New wearable sensors for dolphins could reveal the cost of human disturbances in marine habitats, say researchers.

Tiny fluctuations in the time between each beat of your heart can provide clues about how much stress your body is experiencing.

A nearly invisible e-tattoo that attaches to the palm and connects to a smart watch can tell when you're stressed out.

Embroidering power-generating yarns onto fabric could offer a low-cost, scalable way to make wearable devices.
