Scientists have created tiny disk-shaped particles that can swim on their own when hit with light, akin to microscopic robots that move through a special liquid without any external motors or ...

A light-harvesting wireless sensing system is proposed for indoor lighting control. A low-power light sensor and motion sensor operates on a photovoltaic cell that charges based on ambient daylight ...

We consider the problem of illumination control in a networked lighting system wherein luminaires have local sensing and actuation capabilities. Each luminaire: 1) consists of a light-emitting diode ...
