Stretchable antenna keeps wearable health sensors in tune with human health

Wearable health monitors are designed to move with the body.

But for many devices, movement creates a problem: The more a person bends, stretches, reaches or runs, the harder it can be for the device to keep a stable wireless connection.

Penn State researchers and international collaborators set out to solve that problem by developing a soft, stretchable antenna that can keep working even when pulled in different directions.

The work, published in Nature Communications, could help make wearable health monitors more reliable during everyday activity. ...
