Research and Events

Energy Harvesting with Texas Instruments

The second law of Thermodynamics states that energy will naturally flow from more organized states to lower level states that are more distributed and disorganized. Traditionally, the energy loss was something that was just accepted, but scientists have increasingly been paying attention to this ‘waste’ energy and have developed ways to harness and recover energy that would otherwise naturally dissipate.
