A Fluidic Vibrational Energy Harvester for Implantable Medical Device Applications

A broadband vibrational energy harvester

We propose a design for an energy harvester which has the potential to harvest vibrational energy over a broad range of ambient frequencies. The device uses two flexible ceramic piezoelectric elements arranged in a buckled configuration in the absence of vibrations. Experimental data show that this design allows enhanced harvesting of energy relative to a comparable cantilever design, both for ...

A Stabilized Photovoltaic Energy Harvester for Discrete-Time-Regime Applications

In this paper we present a photovoltaic energy harvester, realized in 0.35-μm CMOS technology. The proposed system collects light energy from the environment, by means of 2-mm2 on-chip integrated micro-solar cells, and accumulates it in an external capacitor. While the capacitor is charging, the load is disconnected. When the energy in the external capacitor is enough to operate the load for a ...

Demo Abstract: A Platform for Implantable Medical Device Validation

Designing bug-free medical device software is difficult, especially in complex implantable devices that may be used in unanticipated contexts. In the 20-year period from 1985 to 2005, the US Food and Drug Administration’s (FDA) Maude database records almost 30,000 deaths and almost 600,000 injuries from device failures [8]. There is currently no formal methodology or open experimental platform ...

Models for 31-Mode PVDF Energy Harvester for Wearable Applications

Currently, wearable electronics are increasingly widely used, leading to an increasing need of portable power supply. As a clean and renewable power source, piezoelectric energy harvester can transfer mechanical energy into electric energy directly, and the energy harvester based on polyvinylidene difluoride (PVDF) operating in 31-mode is appropriate to harvest energy from human motion. This pa...
