Several parts of ur body are under constant movements continuously or intermittently. The Thoracic (chest) regions of our body exhibit a continuous rhythmic movement from birth to death. The Contraction and Expansion of the lungs are responsible for this movement.
The intake of air during breathing causes the lungs to expand; subsequently the intercoastal mucles are relaxed and it causes the outward movement. When the air is given out, the reverse of this process occurs. This expansion and contraction can be made use of by a dynamo and is coverted to electricity. The contraction and expansion varies from person to person and the amount of electricity obtained also varies accordingly.
The belt has two portions connected with an elastic connection, which allows expansion and contraction. This transmits the movements to the gearbox. The leather belt is used to hold the board in front of the chest.
In one portion of the belt, the plastic board is fastened with the help of a clip.The size of the board will be about 15 cm x 9 cm. This board holds the following
The gearbox is made up of plastic. The expansion caused by the intake of air during breathing - rotates the armature of the Dynamo with the help of the Gearbox.
The connection given from the gearbox to the armature of the small Dynamo facilitates easy rotation of the armature. Electricity is produced by the Dynamo in accordance with the rate of rotation of the armature and is stored in the chargeable battery.
The Diode is fitted in the wire between the chargeable battery and the Dynamo. It is to prevent the electricity taking a reverse route from the battery to dynamo.
The electricity produced by the Dynamo is stored in the chargeable battery. This electricity can be taken our for utilization through an EP socket connected by a wire.
These are used for fastening Gearbox, Chargeable Battery, Dynamo, Belt and Cover with the board.
This Plastic Cover is fixed with the board and is used to cover the entire system. It conceals the system with in the shirt. In this cover the EP Socket (Output) is also fitted.
The electricity Produced and Stored by this method can be used for tiny electronic applications like Pocket Radio, Walkman and Small Fan. The maximum output will be in the range of 3 volts DC.
