Zinc oxide nanowires‐based flexible pressure sensor

Embedding piezoelectric nanowires within a soft elastomer material should provide superior pressure sensing transducer, exploiting the properties of nanowire while maintaining flexibility. Here, flexible sensor has been fabricated on Kapton substrate and incorporated layer polydimethylsiloxane with embedded zinc oxide as mechanism. In response to applied compressive up 127 kPa, device generated voltage, between electrodes either side nanowire/polydimethylsiloxane layer, sensitivity 23.6 mV/kPa, which is 100 times greater than previously reported nanostructure-based sensors.
