The Battery-less Silicon on Thin Buried Oxide (SOTB) demonstrator, built using the c2 platform by AND Technology Research, uses the Renesas RE Family’s MCU powered from a Supercap that is charged using a photovoltaic (PV) panel, negating the need for a battery. The charged Supercap enables the demonstrator to measure temperature, humidity and light; and sending those readings via Bluetooth® Low Energy (LE) to a phone where sensor readings are displayed on a custom application.
