Improving the lifetime of an energy harvester

We can make products work for years on high-endurance batteries, though they require maintenance and are clunky, heavy and not-so-durable. So engineers, product designers and tech evangelists have for the last decades been trying to find ways to never use batteries again. As a result, energy harvesting and low power engineering have come a long way. TWTG created Light Energy, an energy source that can use down to 200 lux of light, with supercapacitors that can be used for 75,000 to 100,000 cycles. Although this is a best-case, theoretical scenario, it’s already sufficient for a lot of different IoT applications, including their communications. But we asked ourselves the question if we can make the technology adapt to its own deterioration. This talk will address a new adaptive scheduler for Light Energy to increase durability, reliability and eventually create a world of Internet of Things that isn’t fully relying on batteries.
