The main aim of the project is to generate electrical energy. The power generation which is designed to fit onto the outside of the knee, dynamo rotates as the knee joint goes through a walking motion. From mobile phones to laptop computers, society has become increasingly dependent on portable electronic devices. Because batteries almost exclusively power these devices, and the energy per unit mass in batteries is limited, there is a trade-off between device power consumption, battery weight and duration of operation. This trade-off is particularly severe in the design of powered prosthetic joints that need to be lightweight while performing their sophisticated task over a full day of typical use. The knee itself is an ideal starting point for energy generation as it has a large change in angle during walking and does so at significant speeds. A dynamo attached to the joint could therefore generate large amounts of power.

 

Salient Features:

1. Power generation using knee motion
2. It does not cause any environmental pollution like the fossil fuels and nuclear power.
3. Knee set up also generates power from free source of energy.
4. Conservation of energy.
5. Storage of energy into rechargeable battery.
6. By using this project, we can save more power. That is, we can reduce the wastage of power.

Advantages:

1. This system helps in energy generation.
2. Efficient and low-cost design.
3. Easy to wear and operate.

Major components:

1. Battery
2. Charging circuit
3. Dynamo
4. DC Generator
