On-Skin Wearable Bioelectronic Device Uses Breathable, Stretchable Material

Researchers at the University of Missouri have made a significant breakthrough in their ongoing development of an on-skin wearable bioelectronic device. Zheng Yan’s lab recently added an important component to the team’s existing ultrasoft, breathable and stretchable material. The key feature: wireless charging — without batteries — through a magnetic connection.
