A lead-free flexible energy harvesting device

A metal-piezo-metal (M π M) based single-pixel (sensing element or energy harvester) 1 × 1 cm energy harvester was fabricated using solution-processed potassium sodium niobate films on aluminum-coated polyethylene terephthalate (PET) substrates. Initial measurements using a full-wave diode bridge re...

Description
Summary:A metal-piezo-metal (M π M) based single-pixel (sensing element or energy harvester) 1 × 1 cm energy harvester was fabricated using solution-processed potassium sodium niobate films on aluminum-coated polyethylene terephthalate (PET) substrates. Initial measurements using a full-wave diode bridge rectifier circuit show a real-time response time of ( ∼ 0.13 s) on the application of variable pressure. The magnitude of the voltage signal generated is ∼ 40 mV greater than the expected rectification drop of ∼ 1.4 V, suggesting significant charge transduction in the harvester.
