by using smart sensors (which following pricipal of Piezo electricity) we can make electricity here in this project we will place smart sensors in the high dense roads (such as traffic jam places in some cities) as this sensors convert static energy of vehicles into power and this can be used for lightning the streets and so on.and similarly by using smartsensors we can extend its application for vehicle tracking, navigation and so on.Using the same smart sensors we need to place those by making 8slots in the wheel of goods train (since indianr ....etc

An actuator is a component of machines that is responsible for moving or controlling a mechanism or system.

An actuator requires a control signal and source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic or hydraulic pressure, or even human power. The supplied main energy source may be electric current, hydraulic fluid pressure, or pneumatic pressure. When the control signal is received, the actuator responds by converting the energy into mechanical motion.

An actuator is the mecha ....etc

Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

A guidance system for helping the blind find the way is described. Means to generate modulated signals of different frequencies is there and also a means to amplify and transmit these signals through conductors along the path of the journey. A cane recieves the signals through oscillating means responsive to each signal. It also comprises an amplifier to amplify the signals so that it can be detacted by many persons carrying such recievers along the path.

An oscillator, amplifier and a pulse generator makes up the reciever stick. This syst ....etc

POTENTIAL OF PIEZO ELECTRIC ECOFLOOR FOR GENERATION OF ELECTRIC POWER

The need to generate electricity is the demand for today s life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage of clean electricity. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows that the health burdens are extreme in areas where power stations (based on coal, Ignite, and oi ....etc
