Experimental validation of a microcontroller-based wireless device to quantify head impacts

A microcontroller-based wireless medical device was designed and developed to measure acceleration during head impacts in contact sports. This device is capable of measuring linear acceleration, time of occurrence, and duration of any form of impact or collision. In order to validate the acceleration values from the device, an experimental set-up was built to mimic head collisions. The focus of this paper is to elaborate the design and various techniques involved in experimental validation of the device.
