Publication number: 20240171093Abstract: A transducer is provided for converting mechanical energy to electrical energy. The transducer (100) comprises: a substrate (120); a ferroelectric element (110) adhered to the substrate (120); and a first and second electrode (114, 115) in electrical contact with the ferroelectric element (110). The first and second electrode (114, 115) are arranged to receive charge resulting from ferroelectric domain switching of the ferroelectric element (110) in response to mechanical loading of the transducer (100). The ferroelectric element (110) is partially polarised, so that a mechanical load cycle imposed on the transducer results in a reversible cycle of ferroelectric domain switching.Type: ApplicationFiled: February 18, 2022Publication date: May 23, 2024Inventors: Wenbin KANG, John HUBER
