Wearable Energy Harvester
We waste energy all the time, even sitting and breathing. Now, Dr. Hyekyoung Choi and Min Ju Yun's research team from the Energy Conversion Materials Research Center, Korea Electrotechnology Research Institute (KERI), has developed a technology that can increase the flexibility and efficiency of a thermoelectric generator to the world's highest level by using "mechanical metamaterials" that do not exist in nature.
(Stretchable/flexible thermoelectric generators using metamaterials)
The deformable gasket used by Dr. Hyekyoung Choi's team has a metastructure, which greatly increases the structural stability of the thermoelectric generator. It can be transformed into various shapes, stretches well like human skin, and is easy to attach anywhere. In addition, the partial air gap inside the gasket has excellent insulating properties, preventing heat loss and securing the efficiency of the thermoelectric generator by increasing the temperature difference by up to 30% compared to existing flexible thermoelectric generators.This achievement is expected to receive great attention in the field of IoT and AI-based wearable devices. Existing wearable devices had the disadvantage that they had to have a separate power supply such as a battery, but with KERI thermal energy harvesting technology, they can simply be attached to the body to produce electricity using body heat, and even supply power directly through the module.
( Via Techxplore.)
Everyone's favorite example of energy harvesting wearables is the stillsuit from Frank Herbert's epochal 1965 novel Dune.
It's basically a micro-sandwich; a high-efficiency filter and heat-exchange system. The skin-contact layer is porous. Perspiration passes through it, having cooled the body. Motions of the body, especially breathing, and some osmotic action provide the pumping force.
