# Thermal-Powered Wearable Generator This Thermo Generator Works as a Wearable Device Battery By Michael Baxter | Published 2014-04-14 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/wearable-device-battery References: [psfk](http://www.psfk.com/2014/04/wearable-device-is-powered-by-its-owners-body-heat.html) & [kaist.ac.kr](http://www.kaist.ac.kr/html/en/) [Wearable](https://www.trendhunter.com/trends/breathing-wearable) devices are amazing pieces of tech but they have their own issue; this [wearable device battery](https://www.trendhunter.com/trends/energy-storage-technology) is looking to solve that issue. The battery will allow wearable devices to essentially last forever by using the user's body heat to power the battery, which in turn powers the device itself. It's only a matter of time before smart watches become the norm. With that on the horizon, users will be looking for a sustainable source of energy to power the devices, and this is where the [KAIST](https://www.trendhunter.com/trends/ultrathin-camera-tech) “wearable thermo-element" comes into play. The strip battery is made of fiberglass, which can be easily embedded into clothing and other devices. The strip is only 10cm, so it can be concealed and it powers the devices perpetually. This strip will make buying wearable devices much more accessible. ## Trend Insights (Trend Hunter) - Score: 2.3/10 - Popularity: 23% | Activity: 37% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Key Themes Behind This Trend - **Sustainable Energy Generation:** Developing technologies that harness body heat to power wearable devices, providing a sustainable and perpetual energy source. - **Embedded Power Sources:** Creating flexible, lightweight power sources that can be easily embedded into clothing and other wearable devices. - **Extended Device Lifespan:** Designing battery solutions that significantly extend the lifespan of wearable devices, offering long-lasting functionality. ### Where This Applies - **Wearable Technology:** The wearable technology industry can leverage thermal-powered generators to enhance the performance and longevity of their devices. - **Textile and Fashion:** The textile and fashion industry can integrate thermal-powered generators into clothing, allowing for sustainable charging of wearable devices. - **Consumer Electronics:** The consumer electronics industry can adopt embedded power sources to improve the energy efficiency and convenience of their products. ## Related on Trend Hunter - [Stretchable Sweat-Activated Yarn Batteries](https://www.trendhunter.com/trends/yarn-battery.md) - [Battery-Free Health Wearables](https://www.trendhunter.com/trends/uci.md) - [Self-Charging Fitness Trackers](https://www.trendhunter.com/trends/the-mother-bracelet.md) - [Kinetic Power Health Wearables](https://www.trendhunter.com/trends/mother-bracelet.md) - [Thermal Layering Systems](https://www.trendhunter.com/trends/uniqlos-heattech.md) - [User-Powered Health Trackers](https://www.trendhunter.com/trends/bheart.md) - [Heat-Navigating Wearables](https://www.trendhunter.com/trends/wati.md) - [Menopause-Focused Temperature Bands](https://www.trendhunter.com/trends/thermaband.md) - [Temperature-Monitoring Earrings](https://www.trendhunter.com/trends/thermal-earring.md)
