The National Science Foundation (NSF) Directorate for Engineering (CFDA 47.041) awarded a $275,000 Project Grant to The Pennsylvania State University, doing business as Penn State, to develop an environmentally benign replacement for lead-containing piezoelectric transducers. The project aims to fabricate nano-structured silicon devices that can leverage a newly observed phenomenon, space charge induced flexoelectricity, to create high-performance transducers for sensing, actuation, and energy harvesting applications. In addition to the fabrication work, the investigators will develop a computational framework to simulate the interaction between strain gradient, electric field, and charge carrier diffusion to optimize the transducer design. This research seeks to create a non-toxic, environmentally friendly alternative to traditional lead-based piezoelectric materials, which are estimated to have an annual worldwide production between 1,250 and 4,000 tons. The project will run from August 1, 2023 to July 31, 2026.
