# Self-Charging Activity Trackers MEDIROM is Opting-in for the MOTHER Self-Charging Tech By Kalin Ned | Published 2020-07-09 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/selfcharging-tech References: [businesswire](https://www.businesswire.com/news/home/20200618005445/en/MEDIROM-Announces-Order-MOTHER-World%E2%80%99s-Charging-Activity) & [mobileidworld](https://mobileidworld.com/japanese-hospital-places-order-mediroms-self-charging-mother-wearable-061902/) MOTHER is a self-charging tech device that utilizes thermoelectric technology to convert body heat into the electricity needed to power it. Unveiled at CES 2020, the product has captured the attention of the medical community and recently, MEDIROM—"which operates over 300 salons [in Japan] under Re.Ra.Ku brands and others"—placed an order for MOTHER. The self-charging tech has immense implications for the lifestyle and healthcare sector. Since placing the order with Kansai Medical University Hospital for MOTHER, MEDIROM has reported having "numerous inquiries from the medical sector, including rehabilitation centers, medical institutions, pharmaceutical companies, and nursing homes." The MOTHER wearable is capable of tracking user health and activity over time, including data for sleep length and quality, calorie consumption, and other biometrics. The fact that it doesn't require to be charged adds another piece of convenience. ## Trend Insights (Trend Hunter) - Score: 4.9/10 - Popularity: 69% | Activity: 68% | Freshness: 9% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What Makes This Trend Stand Out - **Self-charging Tech:** The self-charging tech has the potential to disrupt the wearable technology market by providing a convenient and sustainable power source. - **Thermoelectric Technology:** Advancements in thermoelectric technology can revolutionize the energy industry by converting waste heat into usable electricity. - **Healthcare Wearables:** The development of self-charging activity trackers opens up opportunities for more accurate and continuous monitoring of health and fitness data. ### Sectors Adopting This - **Wearable Technology:** The self-charging tech introduced by MOTHER presents a disruptive innovation for the wearable technology industry. - **Energy:** Thermoelectric technology can disrupt traditional energy sources by harnessing waste heat for power generation. - **Healthcare:** The healthcare industry can benefit from self-charging activity trackers by enabling better patient monitoring and data collection. ## Related on Trend Hunter - [Kinetic Power Health Wearables](https://www.trendhunter.com/trends/mother-bracelet.md) - [Battery-Free Health Wearables](https://www.trendhunter.com/trends/uci.md) - [User-Powered Health Trackers](https://www.trendhunter.com/trends/bheart.md) - [Kinetically Powered Smart Thermometers](https://www.trendhunter.com/trends/bcool-smart-thermometer.md) - [Temperature-Monitoring Earrings](https://www.trendhunter.com/trends/thermal-earring.md) - [Stretchable Sweat-Activated Yarn Batteries](https://www.trendhunter.com/trends/yarn-battery.md) - [Metabolism-Tracking Fitness Rings](https://www.trendhunter.com/trends/ultrahuman.md) - [Menopause-Focused Temperature Bands](https://www.trendhunter.com/trends/thermaband.md) - [Personal Energy Tracking](https://www.trendhunter.com/trends/bodystate.md)
