In the past ten years, much technology development has been made in the area of the internet of things (IoT), wearable electronics, and various sensors systems, large number of miniaturized electronic devices have been developed and used in many aspects of our daily life. Most of these devices, however, will require a battery to operate. It is both inconvenient, and wasteful. On the other hand, Si-based electronic devices have become more and more power efficient, many miniaturized electronics devices consumes only 10s µW power and 10s mW power now depending on the user case. The extremely low energy requirement of these devices and the success in the supercapacitor field has opened a door to us to use some low efficiency electricity generation processes to power these devices.

 

Thin film electric generators based on photovoltaic, electromagnetic, piezoelectric, thermoelectric, and triboelectric effects have received increasing attention because they are simple and low-cost approaches to convert various energy forms into electricity for driving small electronic devices. These thin film electric generators combing with supercapacitors are adequate for applications in military, self-powered sensor systems, and wearable electronics. 

 

In this talk, I will introduce our recent work on the development of low power electricity generators based on photovoltaic, piezoelectric, and triboelectric effects and their applications in wearable electronics and autonomous sensor systems.

Biography:

Ye Tao obtained his PhD in solid state physics from the Engineering Physics department at Ecole Polytechnique, l’universite de Montreal in 1993. He is a Principal Research Officer at the National Research Council Canada, leading the Organic Materials and Devices group at the Advanced Electronics and Photonics Research Centre. He is also the leader of the Functional Devices Thrust for NRC’s Printable Electronics Flagship Program. His research interest has been in the areas of organic semiconductor materials and devices, materials structure-property relationship, charge transport and recombination behaviour, surface and interface physics and chemistry. In the past two decades, he led and successfully completed multiple research projects/programs with industry, other government departments, and universities in the field of organic electronics and printable electrics, with over $10 M research funding. Current research focus is on printable/flexible/wearable electronic devices and circuits, smart surfaces, detectors, sensors, and printed autonomous power supplies for mini sensor systems. Dr. Tao has published over 150 scientific papers in peer refereed journals with an h-index of 52, and holds over 25+ US and international patents.
