Towards a battery-free, self-sustaining IoT
With billions of sensors being installed into IoT networks around the globe every year, many of them beyond the reach of power grids, batteries are being deployed at an alarming rate. It’s alarming because most of them contain poisonous chemicals, most commonly lithium, posing a contamination threat of enormous proportions.
What’s more, the cost of changing batteries in remote locations can be prohibitively expensive, so there’s a strong economic case for eliminating them too, making edge IoT sensor nodes self-sustaining.
