Abstract
This article describes the possibility of using self-contained power sources based on piezo-electric technology which converts kinetic energy of the traffic flow into electric which is located in an inner cavity of a speed bump. The purpose is to provide self-contained power supply system for equipment mounted near pedestrian crossings of children's and youths’ educational institutions. The article shows theoretical results of calculations of electro mechanic parameters for piezo-ceramics when a vehicle runs over it. We have developed an experimental setup to study the influence of mechanical pulse stresses on piezo-ceramic plates. We presented a design of self-contained power supply source based on piezo-electric technology.
