Reversible conductivity recovery of highly sensitive flexible devices by water vapor

Wearable electronics: electrodes healable by water Wearable electronic devices are susceptible to degradation or fatigue fracture, but now the aged electrodes of the devices can be healed by simple water vapor treatment. A group of international researchers led by Prof Lifeng Cui from Dongguan Unive...
