The problem with depending on one source of power in the drive toward the battery-free operation of small biomedical devices, remote sensors and out-of-the-way gauges is that if the source is intermittent, not strong enough or runs out altogether, the device can stop working. A small MIT research team has developed a low-power chip design capable of simultaneously drawing power from photovoltaic, thermoelectric, and piezoelectric energy sources. The design also features novel dual-path architecture that allows it to run from either onboard energy storage or direct from its multiple power sources.
