Autonomous Miniature Solar Energy Power Supplies for IoT Sensors and Medical Implants
By Professor Alison Lennon
This webinar will explore the potential and technology required for solar powered IoT sensors and sub-dermal medical implants. Australia has many applications which can benefit from low cost automated sensing. These include wide area sensing for agriculture, early detection of natural disasters (e.g., bushfires) and biomedical monitoring. Technologies which can be autonomously powered using solar energy provide the key benefits of reduced cost and size. This webinar will focus on the use of silicon solar cell arrays coupled with a thin film lithium ion battery to provide an efficient and low-cost power supply for both outdoor and subdermal medical implants. Use of silicon enables high energy conversion efficiencies, low toxicity and paves the way for large scale integration on a low-power wireless chip, a critical step for massively reducing cost.
