摘要：
We report on fully flexible and transparent piezoelectric touch sensors based on Zno nanowires (NWS). Their piezoelectric properties are further enchanced by incorporating BaTiO3 into the capping layer on nanowires. Felexibilty is improved by a highly transparent carbon nanotubes silver nanowires demonstrates a large increase of the output voltage (similar to 3.3 V) from the touch sensor compared to the voltage (similar to 50 mV). Mechanical bending tests reveal that the BaTiO3-added capping layer did not show significant degradation in change of resistance. Our results suggest that the piezoelectr5ic touch sensors are promising for next-generation flexible touch sensors, wearable, and rollable touch panels. (C) 2015 WILEY-VCH Verlag GmbH & Co.
