Energy harvesting and new sensors – what the future holds
Prof. Chris Bowen, Associate Dean (Research), Faculty of Engineering and Design, University of Bath

About the lecture 

The Internet of Things has led to significant demand for new sensors and energy harvesters. It is expected that there will be over 75 billion connected devices, sensors, and actuators globally by 2025.

In this lecture, Prof. Bowen provides an overview of smart materials capable of harvesting mechanical, thermal, and chemical energy -  highlighting the important role of these new functional materials in creating next-generation sensors and self-powered systems. Prof. Bowen discusses piezoelectric, pyroelectric and ferroelectric materials which are able to interact with both heat and mechanical loads. In cases where these properties present in the same material, he highlights the intriguing prospect of a material that can harvest energy from multiple sources including vibration, light and heat.

Prof. Bowen also discusses new and emerging applications for these fascinating materials, such as water-splitting for hydrogen generation and water treatment for disinfection.
