Abstract
The invention discloses a fabric substrate piezoelectric sensor based on zinc oxide nanorod structures and a preparation method of the fabric substrate piezoelectric sensor. The piezoelectric sensor comprises a polyvinylidene fluoride film serving as a middle layer and polyester fabric electrodes which are arranged on the two sides of the polyvinylidene fluoride film and serve as an upper layer and a lower layer; and a layer of zinc oxide nanorod with a piezoelectric effect is grown on each polyester fabric electrode. The polyester fabric electrodes, on which the zinc oxide nanorods are grownthrough a two-step low-temperature hydrothermal method, serve as the upper layer and the lower layer of the sensor; and meanwhile, the polyvinylidene fluoride film with the piezoelectric effect is introduced into the middle layer of the sensor. The fabric-based piezoelectric sensor can generate the piezoelectric effect under the action of an external force to convert external mechanical energy into electric energy, can be used for monitoring gesture changes and sensing different position information of a human body, and has great significance to detection of human body information.
