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. You’d still need to charge them however, and in some cases adding a USB port (micro USB or type C) may negate the benefit of having a thin flexible battery, but Panasonic has a solution as the company added wireless charging capability to their flexible batteries.

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.
