The purpose of this project was to evaluate a novel piezo-floating-gate (PFG) sensor’s ability in measuring the various G-forces experienced by pilots during flight. To evaluate the sensing abilities of the PFG, an impact testing experiment was conducted to determine the relation between the outputs of the PFG relative to the experimental input. The experimental setup was designed to replicate the clamping force that the jaw produces on a mouth guard. For simplicity, this project modeled the jaw clamping as an instantaneously applied constant compressive force. Through experimentation it was apparent that a linear trend existed between the force applied to the PFG sensor and the maximum percentage change in the output frequency. A wider range of applied force is still needed in order to determine an accurate mathematical model between the outputs of the PFG relative to the input force applied.
