On page 37, S.‐W. Kim and co‐workers report unidirectional high‐power generation from piezoelectric nanogenerators via stress‐induced dipole alignment from single‐crystalline piezoelectric perovskite ZnSnO 3 nanocube/polydimethylsiloxane hybrids. This is achieved without applying electrical poling. A recordable large output voltage of about 20 V and an output current density of about 1 μA cm −2 from the device are successfully obtained while rolling under a vehicle tire.
