“…Reference [45] involved a study of the optimum number, dimensions, and configuration of energy harvesters attached to the pacemaker leads inside superior vena cava (SVC) to harvest energy from blood flow. The authors carried out simulation and found that a matching resistance of 35 MΩ produced a maximum power of »9 μW with eight harvester beams.…”

The human body contains a near-infinite supply of energy in chemical, thermal, and mechanical forms. However, the majority of implantable and wearable devices are still operated by batteries, whose insufficient capacity and large size limit their lifespan and increase the risk of hazardous material leakage. Such energy can be used to exceed the battery power limits of implantable and wearable devices. Moreover, novel materials and fabrication methods can be used to create various medical therapies and life-enhancing technologies. This review paper focuses on energy-harvesting technologies used in medical and health applications, primarily power collectors from the human body. Current approaches to energy harvesting from the bodies of living subjects for self-powered electronics are summarized. Using the human body as an energy source encompasses numerous topics: thermoelectric generators, power harvesting by kinetic energy, cardiovascular energy harvesting, and blood pressure. The review considers various perspectives on future research, which can provide a new forum for advancing new technologies for the diagnosis, treatment, and prevention of diseases by integrating different energy harvesters with advanced electronics.

“…[13] At present, a large of cases of reliance on TENG to harvest biomechanical energy have been reported, such as joint activity, [14] muscle movement, [15] kinetic energy during body movement, [3c,16] heartbeat, [5c,17] breathing, [18] and blood flow. [19] In this work, we introduce an insole hybrid nanogenerator (IHN) based on TENG and PENG. The parts of the forefoot and hindfoot are respectively composed of a sandwich structure TENG and an arched PENG.…”

Harvesting biomechanical energy to power wearable electronic devices shows great potential in the field of the Internet of Things. An insole hybrid nanogenerator (IHN) has been designed based on a combination of multilayered triboelectric nanogenerator and arched piezoelectric nanogenerator. The IHN not only can convert the mechanical energy of the footsteps into electricity, but also distinguishes three kinds of motion states: walking, stepping, and jumping. A maximum open‐circuit voltage of 150 V and a short‐circuit current of 4.5 µA are achieved from human body motions. After walking for 8 min, the IHN can charge a 100 μF capacitor to 2.5 V. Then, a self‐powered dorsalis pedis artery monitoring system is designed, which can detect the pulse signals of the dorsalis pedis artery in real‐time. The integrated design of energy collection, storage, and utilization has important application potential in future self‐powered monitoring of patients and intelligent analysis of blood supply to the lower limbs in a professional athlete.

“…Other studies have looked into attaching various piezoelectric energy harvesting structures onto the pacemaker lead wire to reduce the need for extra procedures [15][16][17], but the bulky size of these designs increases the difficulty of lead wire implantation and may increase the chance of post-operative complications. 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.…”

Patients who have an implantable cardiac pacemaker that survive beyond the operational life of the device require replacement surgeries that increase healthcare costs and may possibly introduce post-operative complications such as infection. In this paper, we propose a piezoelectric energy harvester design for powering pacemakers to extend their operational life. The design uses a thin strip of piezoelectric PVDF that captures energy from bending of the lead wire. We assemble a prototype to validate a finite element model, and then use the finite element model to characterize the power output of the design based on a cantilever beam loading condition, where displacement at the cantilever tip simulated heart motion. The voltage output from the prototype was compared to the output from the finite element simulation and the finite element simulation provided a good estimate of the voltage output. Further finite element analysis showed that for a 10 cm long section of the proposed design, a 9.1 mm tip displacement provided a power output of 1 μW and a voltage output of ±1.4 V during each cycle.
