CMOS Indoor Light Energy Harvesting System for Wireless Sensing Applications

Download or read book CMOS Indoor Light Energy Harvesting System for Wireless Sensing Applications written by Carlos Manuel Ferreira Carvalho and published by Springer. This book was released on 2015-07-30 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system.
