The patch that can stimulate sweat on demand

Sweat is an incredibly useful resource for medical research, but whilst it provides us with some invaluable information, it’s also pretty uncomfortable for most of us, especially during our regular working day.  Hence it’s something that we usually try and avoid as much as possible.

Researchers from the University of Cincinnati have come up with an ingenious solution however that stimulates sweat glands in a small patch of skin, thus generating the sweat required to gather the information, without causing us to overheat.

The project, which was documented in a recent paper, uses a device around the same size as a Band-Aid.  The device uses a chemical stimulant to produce sweat, even if we’re relaxing on the sofa.  In addition to analyzing the sweat produced, the device also analyzes the amount of sweat, thus providing crucial insights into the hormones or chemicals the biosensors measure.
