Linear Technology: How the Internet of Things Can Take Advantage of Wireless Charging & Energy Harvesting

August 31, 2016 // By Tony Armstrong
State-of-the-art and off-the-shelf energy harvesting (EH) technologies, for example in vibration energy harvesting and indoor photovoltaic cells, yield power levels on the order of milliwatts under typical operating conditions. While such power levels may appear restrictive, the operation of harvesting elements over a number of years can mean that the technologies are broadly comparable to long-life primary batteries, both in terms of energy provision and the cost per energy unit provided. Moreover, systems incorporating energy harvesting will typically be capable of recharging after depletion, something that systems powered by primary batteries cannot do.
