  This paper investigates the usage of a hybridized Pyro-Piezo Ferrofluidic
harvester to capture useful energy from ambient vibration and temperature
fluctuation. Consisting of a ferrofluidic core, the proposed device utilizes
pyro and piezoelectric materials to charge an integrated ultracapacitor for
'trickle' energy harvesting and usage. In particular, a wearable or implantable
hybridized crystal quartz piezoelectric and PZT pyroelectric based ferrofluidic
harvester is characterized under human ambient energy boundaries. The frequency
associated with typical bodily movement such as walking and strenuous bodily
movement such as running was determined via accelerometer and analyzed via fast
fourier transform, with determined mean frequencies of 1.7 Hz for typical
bodily movement and 4.3 Hz for strenuous movement. Under an optimal continuous
harvestation period of ~24 hours, the CQF harvester was characterized with a
energy harvestation of 7.89 MJ
