Powering Pacemakers with Heartbeat Vibrations

PVDF Energy Harvester for Prolonging the Battery Life of Cardiac Pacemakers

“…The helical design proposed by Dong et al, is small compared to the other pacemaker lead wire energy harvesters [15], but the helical structure is unable to effectively capture energy from bending due to the cancellation of some of the charges as the helical structure undergoes simultaneous tension and compression at different areas of the structure. Karami et al, and Ansari et al, looked into replacing the batteries of the pacemaker with a PEH to harvest energy from chest motion, but the removal of the battery altogether introduces a risk of device failure if problems arise in the PEH, whether that be from insufficient power generation or fatigue failure of the PEH structure [18,19].…”

“…As the heart contracts and expands as it beats, the lead wire bends, as shown in Figure 2b. By placing a piezoelectric energy harvester in the lead wire, the energy This paper discusses a preliminary study that investigates if power generation from the proposed design is enough to power a pacemaker based on a power consumption of 1 µW [18]. In the body, the pacemaker lead wire is anchored at the point where it enters the vein and fixated to the inner wall of a beating heart, as shown in Figure 2a.…”

Investigation of non-linear orthogonal spiral piezoelectric energy harvester for Heavy Haul through simulated data

“…pVEH are devices capable of converting the kinetic energy always present on machines with moving parts [4] into electrical energy through the piezoelectric phenomenon. Energy Harvesters based on piezoelectric materials have been widely used in many fields [5][6][7][8][9][10] and had a boost in the last decades [11]. These devices are characterized by their high-power density, compact size, and high energy conversion efficiency [12].…”
