AbstractBruise Age Measurement Sensor Senior Design project was to build a portable device from scratch to be able to measure the age of a bruise for non-verbal child abuse victim, specifical under the age of three. Due to limited research on bruise metabolism, the aspect of aging a bruise is ongoing and the device will help aid in future bruise research. Ideally the device, with more human subject research though Institutional Review Board (IRB) approval, will help to measure how a bruise will change over time to be able to approximate the bruise. The device was designed via solidwork and 3D printed to be handheld, portable, and battery powered. As well the device uses Arduino and Teensy Microcontrollers, a micro-spectrometer, eight LEDs, and a micro-SD card. The device takes measurements within seconds, turns on all LED’s, the spectrometer gets the spectroscopic readings, and transfer the recorded intensities to be stored on a removable SD card. Once bruise metabolism research is completed, and the approximation of a bruise is able to be defined this device can eventually be used the field by physicians, social workers, and law enforcement officers.
