The pictures on this slide are related to wireless sensor networks. These are distributed networks that monitor physical parameters such as stress and fatigue for buildings and bridges, temperature, moisture and humidity for offices as well as for wineries and farms for precision agriculture. Wireless sensor networks also find application in factories, to remotely monitor motors and other equipment or processes. A remotely distributed, self-powered, wireless network would seem to have a wide variety of applications from consumer to industrial, governmental and military.
