BeFC make electricity with papers and enzymes. Our paper biofuel cells use enzymes to convert sugars and oxygen into electricity for the next generation of ultra-low-power electronics. BeFC technology is metal-free, meaning our biofuel cells are completely organic, simplifying disposal and recycling at end-of-life. Combined with our low-cost, low-environmental-impact digital tags, BeFC enable data opportunities without the downsides typically associated with a battery. With BeFC, unlock a portfolio of sensing opportunities with the ability to transmit data wirelessly over protocols such as BLE, Sigfox, and LoRaWAN. Together, power the future with nature. ©
