Panasonic Showcases Flexible Batteries with Wireless Charging System

Flexible batteries such as PowerStream lithium polymer batteries can be integrated into new application such as smartcards, and could help wearables have longer battery life by adding batteries into clothes, wristbands or chestbands for example.

The solutions showcased at Ceatec Japan 2017 on October 3-6, 2017 were flexible lithium-ion rechargeable batteries with 0.45mm thickness, and 18, 42 and 65mAh capacity.

Such batteries are meant to be attached to human body and clothes for medical and health management applications, or […]

Hexoskin Smart T-Shirt Keep Tracks of Your Activity with 42,000 Data Points per Minute (Crowdfunding)

There are now many smartwatches with electro-optic hear rate monitors, but based on my short experience so far, if you want something accurate and reliable, you’d still better use a chest trap. Another potentially more comfortable option would be to use Hexoskin Smart T-shirt, and on top of the usual fitness data (step count, calorie burn, distance and heart rate), also measure your breathing rate and volume. The T-shirt also supports Bluetooth Smart to send back all the data to your smartphone or other devices such as bike computers or smart watches. The company already has Bluetooth Classic T-Shirt, but there latest versions will offer longer battery life and Bluetooth 4.2 LE connectivity.

Breathing rate and breathing volume. Activity intensity, peak acceleration, steps and cadence. Analog 256Hz […]
