Pendulum base 3D printed electromagnetic energy harvester

Abstract

Abstract In this paper we present for the first time results of works on pendulum base energy harvester fabricated by inkjet 3D printing technology. 3D printing is recognising as a technology that can change the word. First results of harvester operation shows that it is possible to harvest energy in this device with maximal generated voltage near 1.8 V. Printing of this harvester take 12 h and material costs are near 15 USD. It seem that it is possible to utilise this device to power supply a wearable sensors network. Also proposed energy harvester can be used as a simple pedometer.
