Industry s Most Efficient Nano Power Harvesting …

1 Extract and manage W to mW OverviewEnergy Harvesting with breakthrough TI technology allows the development of systems that extract and manage nano Power from a variety of sources such as solar, thermal electric, electromagnetic, and vibration energy . With the reality of years-long battery life, TI technology enables new applications that are simply not possible with traditional battery-powered systems. From solar-powered sensors for wireless monitoring of factories or farms to using body heat to Power sensors on medical and fitness equipment, TI and leading energy Harvesting partners are creating a complete ecosystem for designers to envision and create a battery-less s most Efficient nano Power Harvesting low Power to no Power , TI delivers the most Efficient energy Harvesting technology Low quiescent currents (350 na typical)
