Flexible Single Crystalline PMN-PT Thin Film Nanogenerator and Its Application for Self-powered Cardiac Pacemaker |
| 초록 |
Artificial cardiac pacemaker is widely used to maintain an adequate heart rate. The repetitive surgery are required to replace the pacemakers due to limited lifespan of batteries. Recharging battery in a human body and adopting self-powered nerve stimulation are reasonable solution for solving the problem. This paper describes flexible single crystal PMN-PT thin film nanogenerator (NG) as a high-performance flexible energy harvester for application of self-powered cardiac pacemaker. The NG device generates open-circuit voltage of 8.2 V and short-circuit current of 0.22 mA which is the highest output current among previously reported piezoelectric ceramic-based flexible NGs. We successfully drive 50 LEDs and charge batteries by electric energy harvested from the thin film NG. Finally, the flexible PMN-PT NG is utilized to make direct stimulation of cardiac nerve for artificial heartbeat without external power source. |
