Wearable electronics are becoming more and more commonplace, driving the need for more durable and more energy-efficient technologies. One persisting limitation for these gadgets, however, is the need to charge them - and new technology could soon overcome this restriction.

According to the Korea Institute of Science and Technology (KIST), a research team led by Director Jin-Sang Kim from the Jeonbuk Institute of Advanced Composite Materials was able to develop a "high-efficiency flexible thermoelectric device" capable of autonomously capable of generating a part of the electricity it needs to run from the wearer's body heat.

The Korean research team published their findings in the report titled "Porous organic filler for high efficiency of flexible thermoelectric generator" appearing in the latest Nano Energy journal.
