Abstract
This paper investigates the performance of a novel heart piezoelectric energy harvester. Heart-simulating experiments were based on the electrocardiogram (ECG) signals from different patients. The shape of the ECG signal as the heart motion simulation was investigated for the energy harvester performance. Amplitude-normalized ECG signals of five patients were used as input for a vibration shaker while the electrical performance was recorded. The output results, voltage, the number of energy pulses generated, and the width of the generated energy pulses were calculated. Results showed that this novel energy harvester developed 11.40 ± 0.85 V voltage, 26.4 pulses of energy in each heartbeat, and an average pulse width of 0.11 ±0.03 ms. The results showed that the output performance of different patients is still influential. The study contributes to broadly testing piezoelectric energy harvesters for leadless pacemakers.
