New Device Uses Your Body For Its Battery
March 17, 2021 | 1 Comment
A University of Colorado at Boulder team of engineers has developed a new device that you can wear like a ring or bracelet and that harvests power from your own body heat energy. The device, described in a paper published in the journal Science Advances, is stretchy enough that you can wear it like a […]

Defective Crystals Help Convert Waste Heat To Electricity
March 10, 2021 | Leave a Comment
Nagoya Institute of Technology researchers have attempted to uncover the role that nickel (Ni) defects have in the crystal structure of these alloys and how their desirable thermoelectric properties are a consequence of small changes in strain around defective sites. Half-Heusler Ni-based alloys are thermoelectric materials with the potential for converting waste heat into electricity. […]

A new University at Buffalo study describes a new technology that provides both radiative cooling and solar heating, all in one system and without using electricity or fuel. It could help impoverished communities, reduce cooling and heating costs, lower CO2 emissions. It’s passive cooling like a shade tree provides. The researchers have been exploring how […]

Now 3D Printed and Folded Thermoelectric Generators
February 9, 2021 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Karlsruher Institut für Technologie (KIT) scientists have now developed three-dimensional component architectures based on novel, printable thermoelectric materials. Thermoelectric generators, TEGs for short, convert ambient heat into electrical power. They enable maintenance-free, environmentally friendly, and autonomous power supply of the continuously growing number of sensors and devices for the Internet of Things (IoT) and […]

New Way Found To Make Electricity From Wasted Heat
February 4, 2021 | Leave a Comment
Karlsruher Institut für Technologie (KIT) scientists have now come much closer to their goal of converting waste heat into electrical power at small temperature differences. Electrical power per footprint of thermomagnetic generators based on Heusler alloy films has been increased by a factor of 3.4. The use of waste heat would contribute in a large […]
