So you want to build your own wearable devices? A wearable sensor platform such as the MetaWear can help. It is a tiny board with sensors (temperature, accelerometer, and gyroscope) that you can program using your smartphone. The MetaWear can measure acceleration, rotation, pressure, altitude, and more. It connects to your smartphone or tablet via Bluetooth to allow you to log or stream 6-axis of motion data.
With a solution like this, you can build your own products and test them faster. It can be used to track steps, health, environment, and sports. The sky’s the limit. You can program the board using an iOS or Android app. You can find out more about it on Kickstarter.
