HIGHLIGHTS
- who: Christopher Cheng and colleagues from the Department of Materials Science and Engineering, Penn State University, University Park, PA, USA have published the article: Improving PMUT Receive Sensitivity via DC Bias and Piezoelectric Composition, in the Journal: Sensors 2022, 22, 5614. of /2022/
- what: The receive sensitivities increased by ~2 times when 15 V (75 kV/cm) was applied to the MPB PZT PMUT, due to the increase in the e31,f and a decrease in the relative permittivity.
- how: This paper discusses different PZT compositions and their suitability for ultrasound receive sensitivity . . .
