WIRELESS CHARGER CIRCUIT DESIGN for PACEMAKER


Description

Pacemaker is a medical device that monitors the heartbeat and provides electrical stimulation when the heart beats too slowly or

stops. The implanted pacemakers

use non-rechargeable batteries with a limited lifespan. So, when the battery expires the patient need to replace the whole unit through surgery. The aim of this research is to design a working prototype that wirelessly

charges a pacemaker's battery

Objectives:

Devise a working prototype that wirelessly charges battery of the pacemaker.
The charging visits will be once a year, taking 3 hours at most to be fully
charged.
Charging the battery under the supervision of hospitals' technicians.
The separation between transmitter and receiver will be at least 10 cm.
The transmitted frequency does not harm the human body.
Results:
Using this project will eliminate the number of

replacement surgeries and the patient is expected to have just one charging visit per year

Replicability

Baseline Design Description:
The system consists of two main sections transmitter and receiver. Transmitter coil is placed outside the human body, whereas receiver coil is located inside the human body in the pacemaker. Power source provides a 220V, 50Hz to the voltage adapter. The adapter was used to step down the voltage and convert from alternating current (AC) to direct current (DC). Then the LC Colpitts oscillator generates 12V and 1MHz frequency. The generated alternating current will pass through the transmitter coil inducing voltage at the receiver both primary and secondary coils should be tuned to resonate at the same frequency to enhance charging efficiency using resonant inductive coupling principle. Full wave bridge rectifier takes the received AC and converted to DC since, it is needed to charge the lithium iodine battery. Lastly, Arduino is added to the system to indicate the battery voltage.


Sustainability

The project will use a rechargeable battery with number of 500 cycles to sustain and insure the long life of the battery which will reduce the number of surgeries done to replace the expired battery with a new one. Furthermore, it will save the patient’s money by reducing number of surgeries.


WSIS values promotion

The current situation of a pacemaker is that whenever the battery expires the whole pacemaker unit should be replaced through a surgery. This project aims to design a working prototype of a wireless pacemaker charger using healthy non-radiative method. So that it ensures healthy lives and promote well-being for all pacemaker patients at all ages. Also, it is an economical solution where it saves the patients money by eliminating any further replacement surgeries; providing an affordable lives to patients
