In a study published Aug. 31 in Nature Communications, they show that their tiny thermoelectric generators can provide a practical, cost-effective and mass-producible solution for producing power from only a relatively small difference in temperature. The team’s new silicon-germanium thermoelectric generators can produce this operating in an environment at ordinary room temperature (about 23 degrees Celsius or 73 degrees Fahrenheit) from a copper rod warmed to as low as 45 C (113 F). At the Speed of Bright UT Dallas has earned a reputation for incredibly bright students, innovative programs, renowned faculty, dedicated staff, engaged alumni and research that matters. The design and fabrication of IoT devices incorporating thermoelectric generators was handled by the Texas Instruments team, led by Hal Edwards, a TI Fellow at the company. He explained that hundreds of individual thermoelectric generators, each about the size of a grain of salt, are combined to form what he referred to as a macroscopic harvester.
