Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto …
The Interuniversity MicroElectronicss Centre (IMEC) is an independent research center which deals with nanoelectronics and digital technologies. Their headquarters are situated in Leuven, Belgium. Recently IMEC began to research and prototype Solid State Lithium-ion batteries. Solid State batteries are batteries which make use of solid electrodes and electrolytes. There have been a lot of research …
