Look at the the benefits of open hardware for wearable devices. Compare popular hardware wearable platforms including Simband, Arduino-based solutions, and WaRP

1. Open Source Platforms for
Wearables
Gene Leybzon, June 2015

2. Open Source Hardware Movement
Machines, devices, or other
physical things -- whose
design has been released to
the public in such a way that
anyone can make, modify,
distribute, and use.

3. Examples of Open Hardware

4.  Prototype faster
 Affordable cost of hardware
 Leverage community
 Reduce risk
 Use existing code
