Heart a source of energy to life-saving devices


“The energy due to the position of the object is the potential energy and the energy due to the motion of an object is the kinetic energy of that object.” We all have heard this line in our science classroom back in school. Implementing this simple science that we learned way back in school the researchers have found a way to utilize the kinetic energy of the heart. Researchers have made a device that will charge batteries with hearts kinetic energy The heart would be the source of energy.

The need to have such a device

There are cases when people have to replace or depend on pacemakers, defibrillators or other life-saving implantable devices. These devices are battery powered which needs to be changed after every fixed time period. The process is costly and not every person affords to do it. And also the surgery can induce complications in the already complicated case.

How will it happen?

To overcome this problem of replacement and to find a fix and final solution to this, researchers have come up with a device. This dime-sized device can capture and convert the kinetic energy of the heart into electricity. This electricity can then charge a wide range of life-saving devices. The hearts motion is capable of producing energy that will satisfy the energy needs of these devices.

The actual working

Basically, researchers have come up with tiny solar cells that encourage the heart to beat. Silicon made flexible mesh will do the work. It will be activated with a flash of light. This will create an electrochemical effect which can simulate the heart muscles in a unique way.

The idea came from a previous device that simulated neurons. Then researchers made a mesh that was much thinner so that it could easily wrap itself around the heart. Because the device must not meddle with the normal functions of the heart.

The device consists of tiny nanowires that will attach itself to cardiac cells. a small optical beam will scan the area with a laser. This laser will, in turn, activate the cell and make the heart beat at the same frequency as that of the light. This will help produce kinetic energy than electricity and then charge the batteries of the life-saving devices.

Further advancements

The device is further set to harness the kinetic energy of the lead wire that is attached to the heart. Convert it to electricity and continuously charge the batteries. The newly inserted material is a type of a thin polymer piezoelectric film “PVDF”. If the researchers design the polymer with the porous structure it can convert even the smallest movement into electricity

Future uses

It takes time for the process to take action. But once set it will be a very useful thing that will solve not one but many problems of the medical field. The current device in the discussion is biocompatible, lightweight, flexible, and low profile. But the device is also scalable for multi-functionality.


Science has come a long way and has saved a lot of lives with its advancements. Now science is focusing on making these advancements easy for every person in need. The proposed device is a milestone that will change a lot of things in the future of science.
