No batteries? No sweat! Wearable biofuel cells now produce electricity from lactate

Wearable electronic devices and biosensors are great tools for health monitoring, but it has been difficult to find convenient power sources for them. Now, a group of scientists has successfully developed and tested a wearable biofuel cell array that generates electric power from the lactate in the wearer's sweat, opening doors to electronic health monitoring powered by nothing but bodily fluids.
