Now, charged garments to monitor health

ingestible or flexible technologies.

The devices tend to be some combination of too large, too heavy and not flexible,” said Trisha L Andrew, who led the study published in the journal ACS Applied Materials & Interfaces.

The method uses a micro- supercapacitor and combines vapour- coated conductive threads with a polymer film, plus a special sewing technique to create a flexible mesh of aligned electrodes on a textile backing.

The device has a high ability to store charge for its size, and other characteristics that allow it to power wearable biosensors. Researchers have miniaturised electronic circuit components, until now the same could not be said for charge- storing devices.
