Whether autopowered pacemakers can be associated with linear Motors. In recent years, pacemakers have brought health benefits to countless patients, and they have been favored by more and more patients with heart disease because of their small trauma and good effect. But nothing is perfect. The pacemaker also has the disadvantage of using batteries. It is well known that even the best batteries have energy depletion days. For heart patients, surgery to replace batteries is risky and expensive. On this basis, the relevant departments and agencies have been working on research in this area.
Two scholars at Shanghai military medical University and Shanghai Jiaotong University have finally made a breakthrough by developing a way to charge a pacemaker by cleaning up and filtering its internal energy, according to a small editor of the linear motor. The main principle is to use the motor force of the myocardium itself to drive a miniature generator.
The linear motor editor learned that before that, professionals tried to rely on piezoelectric materials to use cardiac muscle strength to run pacemakers. When the heart is deformed, the electrons of the piezoelectric material are released and attached to the beating heart, so that each time the heart beats, they will bend slightly, producing electric currents. This method is effective, but the effect is not satisfactory. The output voltage is basically no more than 5 microwatts, and most pacemakers require at least 10 microwatts. Two scholars from the former Shanghai Military Medical University and Shanghai Jiaotong University tried to increase the voltage by increasing the deformation of piezoelectric composites. They first made a small capsule out of a tenth of a millimetre thick flexible polymer. After compression, the capsule will return to its original shape. They then attached the piezoelectric composite strips to the sides of the capsule and connected them to the electrodes, and covered the piezoelectric composite strips with a layer of silicone as a protective layer. This layout means that the piezoelectric composite strips are slightly curved from the beginning, and only a small, short pressure is required to generate 15 microwatts of electricity.
When it comes to pacemakers, where linear motors have been used in practice, the small editor wonders whether an autopowered pacemaker can be associated with a linear motor, creating a powerful combination of pacemakers.
