“…Energy harvesting may be done by various methods and all kinds of energy harvesting principles are studies by researchers. Some people are trying to obtain energy using a fuel cell by a chemical reaction between glucose and oxygen, and many people are trying to harvest substantial amount of energy from various mechanical body movements including a knee, body movement, and even a heart wall movement from the heartbeats [38,[42][43][44][45][46][47][48].

Cardiovascular disease is a very serious disease which results in about 30% of all global mortality. Atrial fibrillation (AF) causes rapid and irregular contractions resulting in stroke and cardiac arrest. AF is caused by abnormality of the heartbeat controlling electrical signal. Catheter ablation (CA) is often used to treat and remove the abnormal electrical source from the heart but it has limitations in sensing capability and spatial coverage. To overcome the limitations of the CA, new devices for improving the spatial capability have been reported. One of the most impressive methods is wrapping the heart surface with a flexible/stretchable film with an array of high-density multifunctional micro-sensors and actuators. With this technique, the overall heart surface may be diagnosed in real time and the AF may be treated much more effectively. The data acquisition from the array of multifunctional sensors is also very important for making the new devices useful. To operate the implanted device system, a battery is mostly used and it should be avoided to replace the battery by surgery. Therefore, various energy harvesting techniques or wireless energy transfer techniques to continuously feed the power to the system are under investigation. The development of these technologies was reviewed, and the current level of technology was reviewed and summarized.

“…The difficulties linked with the presently available excitation/energizing system necessitate the pursuit of resonant inductive link based wireless powering system for implantable devices which is cordless, reliable, safer, smarter, environmental friendly and suitable for animal body [11][12][13][14]. To expand the usability of the wirelessly energized implantable electronic devices for continuous patient monitoring in inaccessible and outdoor areas derelict of grid power supply, harvested thermal energy based energizing system can be a partial and accepted solution [15][16][17][18]. Thus, an alternate viable approach in the form of thermal energy based resonant wireless energizing system has been proposed for implantable biomedical electronic sensor.…”

Abstract-In order to energize the biomedical implantable electronic devices wirelessly for in vivo health monitoring of patients in remote and inaccessible areas, an alternate driving energy source is highly desirable and increasingly important. In pertinent to this, a thermal energy driven resonant inductively coupled wireless energizing scheme has been developed for powering biomedical implantable devices. The system is designed to convert the generated heat energy to a high frequency energy source so as to facilitate energy transfer through resonant inductive link to the automated biomedical sensing system allied with the receiver unit. The automated biomedical smart sensor is competent to acquire the body parameter and transmit the consequent telemetry data from the body to the data recording segment. The real-time body temperature parameter in different conditions has been experimented. To ensure its accuracy, the sensed data have been matched with the observations carried out by a calibrated device. The intended scheme can be utilized for wireless monitoring of other health parameters like physiological signals and bladder as well as blood pressure of the patients.

“…Researchers are exploring strategies to harvest energy from various potential sources in the human body [3], [4]. Investigations show the possibility to harvest energy from joint motions by piezoelectric ceramics [5]- [7], chemical reactions of glucose and oxygen in dedicated fuel cells [8], sunlight penetrating the human skin by solar cells [9]- [11], body movements by using nanowire technology [12] or waste heat from the body by using thermoelectric generators [13].…”

Abstract-Energy harvesting devices are widely discussed as an alternative power source for todays active implantable medical devices. Repeated battery replacement procedures can be avoided by extending the implants life span, which is the goal of energy harvesting concepts. This reduces the risk of complications for the patient and may even reduce device size. The continuous and powerful contractions of a human heart ideally qualify as a battery substitute. In particular, devices in close proximity to the heart such as pacemakers, defibrillators or bio signal (ECG) recorders would benefit from this alternative energy source. The clockwork of an automatic wristwatch was used to transform the hearts kinetic energy into electrical energy. In order to qualify as a continuous energy supply for the consuming device, the mechanism needs to demonstrate its harvesting capability under various conditions. Several in-vivo recorded heart motions were used as input of a mathematical model to optimize the clockworks original conversion efficiency with respect to myocardial contractions. The resulting design was implemented and tested during in-vitro and in-vivo experiments, which demonstrated the superior sensitivity of the new design for all tested heart motions.
