“…[28] The LV was selected as a target area for TECH to harvest cardiac energy on its surface due to its dynamic and powerful movement with one of the thickest muscle walls in the heart. [29] As the TECH devices are soft and easily stretch no alterations to the myocardium or changes in strain pattern of the heart are expected. Li et al investigated the best possible implantation site, in terms of maximum energy output for piezoelectrical devices on the heart.…”

Reliability of power supply for current implantable electronic devices is a critical issue for longevity and for reducing the risk of device failure. Energy harvesting is an emerging technology, representing a strategy for establishing autonomous power supply by utilizing biomechanical movements in our body. Here we present a novel “Twistron energy cell harvester” (TECH), consisting of coiled carbon nanotube yarn that converts mechanical energy of the beating heart into electrical energy. The performance of TECH was evaluated in an in vitro artificial heartbeat system which simulates the deformation pattern of the cardiac surface, reaching a maximum peak power of 1.42 W/kg and average power of 0.39 W/kg at 60 beats per minute. In vivo implantation of TECH onto the left ventricular surface in a porcine model continuously generated electrical energy from cardiac contraction. The generated electrical energy was used for direct pacing of the heart as documented by extensive electrophysiology mapping. Implanted modified carbon nanotubes are applicable as a source for harvesting biomechanical energy from cardiac motion for power supply or cardiac pacing.This article is protected by copyright.

“…Anisotropic cardiac function is derived from the different amounts of myocardial tissue between the left and right ventricular walls. 2 More myocardial fibers in the left ventricular walls can cause the left ventricle to generate distinct mechanical work, 3 resulting in region-dependent anisotropic deformation of the heart during blood ejection. 4 Self-oscillating gels, developed by our group, have gained the attention of many scientists and engineers to mimic various dynamic biological oscillatory phenomena, such as a heartbeat.…”
