We have seen many smart wearable devices in the past few months. They are only going to get more sophisticated and compact. New Zealand firm StretchSense is behind a tough fabric sensor that can be worn in a discreet fashion. It is ruggedized, yet lightweight and comfortable for the wearer. It has sewable zones, allowing you to integrate it with your existing clothing items easily.
The sensors stretch easily as you move your body and rely on Bluetooth to communicate with your smart devices. Each kit comes with a flexible fabric stretch sensor, Bluetooth LE circuit, and a coin cell battery. The data capture app is already available on Google Play. The kit sets you back $300 as long as you order early.
