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 ZnSnO3 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.
