Imagine a future where you can go for a run or teach a group exercise class and convert your body heat to power your smartwatch.
This type of technology is what Jianliang Xiao, PhD, associate professor of mechanical engineering at Colorado University Boulder, is developing. “In the future, we want to be able to power your wearable electronics without having to include a battery. . . . The nice thing about our thermoelectric device is that you can wear it, and it provides you with constant power.” Researchers expect the device to be on the market within 5–10 years.
The study is available in Science Advances (2021; 7 , eabe0586). Watch this video at https://bit.ly/3pR5QDF to learn more.
