Sensor Instrumentation to Improve Safety in U.S. Underground Coal Mines

Coal mine safety sensor system to prevent dust explosions

Coal mining is recognized as a dangerous undertaking. Explosions of gases that may exist underground (e.g. methane) and of fine coal dust mixed with air are well-known hazards, in addition to which are unexpected structural collapses. This project is aimed

Self-Adaptive Energy Harvesting

Self-tuning resonant energy harvesting experimental set-up

Vibrational energy harvesting seeks to transform the energy in mechanical vibrations to useful electrical power to operate small electrical devices. Most vibrational harvesters rely upon the resonance of a structure excited by input vibrations to develop the large deformations necessary
