When installing micro-electronic devices in locations that are expensive or hard to reach, or just downright dangerous, you don't want to have to keep returning to swap out a battery cell. City Labs has announced the commercial launch of its NanoTritium betavoltaic power source, a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years.
As the rate of miniaturization of portable technology increases, so too does the need for smaller and smaller batteries to power them. Current devices, such as hearing aids and wireless sensor networks, that draw small amounts of power over an extended period of time have generally relied on coin-cell batteries to keep them running. Now ultra-thin bendable battery technology from Front-Edge Technology (FET), delivering between 10 and 20 times more power, may provide the advances the electronics industry needs.
