  2 Type of Foot - Step Generator Using Piezoelectric Foot Step to produce electricty  These devices may then generate a voltage on every footstep and when mounted in series they will produce a sizeable amount of electricity. For this purpose we here use piezoelectric sensors that use piezoelectric effect Using Mechanical Foot step (Gear & Dynamo) to produce electricity Transfer power from human footsteps to a gear attached to a shaft, the power is then transferred to another gear through a gear based arrangement. Now we attach a generator motor to another gear in order to run the dynamo and generate electricity.    In this Electrical Power Generation Using Foot Steps Project, we are generating electrical  power as non-conventional method by simply walking or running on the footstep. Non-conventional energy system is very essential at this time to our nation. Non-conventional energy using foot step needs no input power to generate the output of the electrical power. This project using a simple drive mechanism such as rock and pinion assembles and chain drive mechanism. For this project- Electrical Power Generation Using Foot Step the conversion of the force energy into electrical energy. The control mechanism carries the rack & pinion, D.C generator, battery and inverter control. We have discussed the various applications and further extension also.    WORKING PRINCIPLE   The complete diagram of the footstep power generation is given below. Only one step is inclined in certain small angle which is used to generate the power. The pushing power is converted into electrical energy by proper driving arrangement. The rack & pinion, spring arrangement is fixed at the inclined step. The spring is used to return the inclined step in the same position by releasing the load. The pinion shaft is connected to the supporter by end  bearings as shown in fig. The larger sprocket also coupled with the pinion shaft, so that it is running the same speed of the pinion. The larger sprocket is coupled to the small cycle sprocket with the help of chain (cycle). This larger sprocket is used to transfer the rotation force to the smaller sprocket. The smaller sprocket is running the same direction of the forward and reverse direction of rotational movement of the larger sprocket. This action looks like a cycle pedaling action. The flywheel and gear wheel is also coupled to the smaller sprocket shaft. The flywheel is used to increase the RPM of the smaller sprocket shaft. The gear wheel is coupled to the generator shaft with the help of another gear wheel. The generator is used here, is permanent magnet D.C generator. The generated voltage is 12Volt D.C. This D.C voltage is stored in the Lead-acid 12 Volt battery. The battery is connected to the inverter. This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This working principle is already explained in the above chapter. This 230 Volt A.C voltage is used to activate the light, fan and etc. By increasing the capacity of the  battery and inverter circuit, the power rating is increased. This arrangement is fitted in a shopping complex, college and wherever the large people walking on the footsteps simultaneously.    Mabuchi 12V DC Generator - 12 VDC - 40 Watts Peak Power - 25 Watts Rated     Brand new electric motor manufactured by Mabuchi    Works great as a generator too    Rated voltage: 12 VDC with 6,000 RPM input    Step up the speed from your wind or hydro turbine and put this compact generator to work    Intermitted duty (be aware of temperature to prevent overheating)    Great for school projects, science fairs, hobbies, etc.    Rated current: 2 Amperes    Rated power: 25 Watts    Peak power (short term maximum): 40 Watts    5 pole armature    Dimensions (not including shaft): 57 mm long x 38 mm diameter (2 1/4" L x 1 1/2" D)    Shaft dimensions: 3.17 mm diameter x 13 mm long (1/8" D x 1/2" L) D-type (flat on one side)    Solder terminals for easy connection (can also use 3/16" quick connect terminals)    Features 2 threaded (M3-0.5) mounting holes on 25 mm centers    Weight: 7.7 oz (218 g)
