Abstract:Abstract-In this paper, we propose a CMOS image sensor with reconfigurable resolution for energy harvesting applications such as video sensor networks. Depending on the available energy, the spatial resolution of the imager can be adaptively reconfigured to save energy for other units on the sensor node. In contrast to early attempts of energy harvesting image sensor, we propose an asynchronous sensor in which the photodetector itself within the pixel can be used as an energy harvesting device, so that the tot… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
