The Underlying Chemistry of Piezo Materials

On February 6, 2019 in All, Energy Harvesting, Power, Sensors by Liam Critchley

The electrical properties of both piezoelectric and piezoresistive materials change when subjected to mechanical deformation. Here, we show how and why these electrical changes are due to changes within the crystal structure at the atomic level and the chemistry involved with these changes.

Understanding the Chemistry of Semiconductor Junctions

On September 21, 2018 in All, Energy Harvesting, Industrial, Power by Liam Critchley

Chemistry plays a major part in why semiconductor materials behave the way they do, and why current can flow through a p-n semiconducting junction. Here, we discuss what effect chemistry has on these junctions, including some of the mechanistic variations that exist in electronics today.
