Low-Power Image Sensor System
The objective of this work is to design a self-powered, environment-adaptive sensor node that maintains a target Quality-of-Service (QoS) in a time-varying environment. A wireless image sensor node will be designed that incorporates a CMOS imager, digital signal processing unit, and RF transreceiver and is powered using energy harvested from the environment. The circuit innovations for the individual components will be coupled with system design and on-line real-time control principles to approach this highly challenging goal of developing a self-powered image sensor node. The self-powered sensor node and reliable energy-efficient image transmission principles created in this work will allow deployment of image sensors and communication networks to cyber-physical systems in various military as well as civilian applications.
