TITLE: Integrated Structures for Multisource Ambient Energy Harvesting
ADVISOR: Dr. Matthew Bryant
DATE: November 5, 2018
LOCATION: EB3, Rm. #3235
ABSTRACT: Energy harvesting from multiple sources ensures a continuous generation of electrical power, especially when one of the ambient sources is intermittently available. A multifunctional, tension modulated, doubly clamped wind-solar energy harvesting concept is proposed and analytically modeled to investigate the effects of tension modulation. A proof of concept energy harvester is fabricated and experimentally investigated to showcase its energy extraction capabilities. The device produces several milliwatts of power under combined wind-solar operation and milliwatts of power under aerodynamic excitation, which is suitable for low powered electronic devices.
BIOGRAPHY: Punnag Chatterjee was born in Kolkata, West Bengal, India. He attended National Institute of Technology – Durgapur, where he earned his Bachelor of Technology in Mechanical Engineering in 2010. He then joined the R&D division of an automobile industry in India, Bajaj Auto Limited as a vehicle suspension design engineer where he worked for three years. He started his MS degree at ISSRL at NC State University in August 2013 and defended his thesis in August 2015. He had been pursuing his PhD right after finishing his MS. His research focus is primarily on hybrid energy harvesting from flow induced vibrations and solar irradiation along with related experimental investigation and analytical modeling.
