Recent progress in flexible and stretchable piezoelectric
Dec 01, 2016#0183;#32;With device areas of #215; cm 2, the output voltages can reach 200 V under bending deformations (peak strain of % and strain rate of % s 1), as shown in Fig. 5(l). Slight human finger motions, in fact, can light as many as 100 blue LEDs simultaneously.
