Abstract

Through a transcutaneoues inductive link has been give power for implanted biomedical device such as a cochlear implant, retinal prostheses and pacemaker. Cardiac pacing involved the electrical stimulation of the heart in order to control timing of the contraction of the heart. In form pulses, the electrical stimulation is generated by a battery powered pacemaker and applied to the tissue of the heart by one or more electrode that one connection to the pacemaker via flexible insulated conductor. In general, the insulated conductors and associated electrodes form is refer to as the “lead”. Nowadays, battery lithium is used because it is the latest development. This battery has been installed in pacemaker but unfortunately, the battery’s power of pacemaker becomes less with time and cannot regenerate the power again to the pacemaker. Hence, the pacemaker cannot generate electrical stimulation. To overcome this problem, a charger was needed. The special charger that has the ability to charge the battery of implant device from outside the body was designed. The external part was designed for the transferring of power to the implanted part and can charge the battery implanted device without using wire. The voltage input and output has been taken. The result shows that the output voltage of primary transformer is highest value than the output voltage of the secondary transformer which is from 12 V to 5 V. Result shows the changing of output waveform from primary transformer to secondary transformer get a movement and has the changing voltage from primary side circuit to secondary side circuit because voltage decreased less than 5 V at secondary transformer to transfer power to implant device. This design was achieved when transformer can transfer more power and has the ability to charge the implanted device.
