Biomechanical Energy Harvesters In article number 2204304, William W. Yu, Wen Jung Li, Walid A. Daoud, and co‐workers demonstrate a high‐performance flexible biomechanical energy harvester by switching its interfacial adhesion via hydrogen bonding interactions and solvent evaporation induced phase separation. This wearable power source can generate a record high peak power density of 20.5 W m −2 Hz −1 under a low biomechanical input of 5 N, and can sufficiently power small electronics through harvesting regular or intermittent human motions.
