  volume = {In press},
  abstract = {Piezoelectric fiber composites ({PFC}) represent an interesting subset of smart materials that can
function as sensor, actuator and energy converter. Despite their excellent potential for energy
harvesting, very few {PFC} mechanisms have been developed to capture the human body power
and convert it into an electric current to power wearable electronic devices. This paper provides a
proof of concept for a head-mounted device with a {PFC} chin strap capable of harvesting energy
from jaw movements. An electromechanical model based on the bond graph method is
developed to predict the power output of the energy harvesting system. The optimum resistance
value of the load and the best stretch ratio in the strap are also determined. A prototype was
developed and tested and its performances were compared to the analytical model predictions.
The proposed piezoelectric strap mechanism can be added to all types of head-mounted devices
to power small-scale electronic devices such as hearing aids, electronic hearing protectors and
communication earpieces.},
