“…Therefore, energy harvesting devices have been studied as an assistant energy source for batteries or independent energy sources for the permanent use of wearable devices without restrictions associated with power consumption. Human energy can originate from a chemical or a physical energy source [4]. Typical sources of physical energy include the thermal and kinetic energy of the human body.…”

Abstract:Energy harvesting has been attracting attention as a technology that is capable of replacing or supplementing a battery with the development of various mobile electronics. In environments where stable electrical supply is not possible, energy harvesting technology can guarantee an increased leisure and safety for human beings. Harvesting with several watts of power is essential for directly driving or efficiently charging mobile electronic devices such as laptops or cell phones. In this study, we reviewed energy harvesting technologies that harvest biomechanical energy from human motion such as foot strike, joint motion, and upper limb motion. They are classified based on the typical principle of kinetic energy harvesting: piezoelectric, triboelectric, and electromagnetic energy harvesting. We focused on the wearing position of high-power wearable biomechanical energy harvesters (WBEHs) generating watt-level power. In addition, the features and future trends of the watt-level WBEHs are discussed.

“…[114] In particular, energy generated from biomechanical motions of the human body holds great promise to power on-body devices, such as wearable pressure sensors or implantable pacemakers. However, current energy-generation devices are made of rigid or brittle ceramic materials, [115] which are neither stretchable to accommodate human motions, nor to enable conformal contact with human skin and/or tissues.…”

The development of ultra‐compliant power sources is crucial for their seamless integration with next‐generation skin‐like wearable and implantable biomedical systems for long‐term health monitoring. Toward this goal, stretchable energy storage and conversion devices (ESCDs), including supercapacitors, lithium‐ion batteries (LIBs), solar cells, and generators are now attracting intensive worldwide research efforts. The purpose of this review is to discuss the latest achievements in the development of such stretchable energy devices in the context of biomedical applications. We first review the viable strategies and methodologies of fabricating stretchable energy storage and conversion devices. Then, we focus on description of various types of soft energy devices from a materials point of view. Furthermore, we discuss the challenges and opportunities in the design of truly conformal soft energy systems, including various key parameters, such as energy density, stability, and scalability.

“…Therefore, dependable power harvesting technologies are required for sustaining implantable bioelectronics operation in vivo for the lifetime of the patient without the need of continuous battery replacements [4]. Advances in implantable bioelectronics such as cardio-stimulators, drug delivery, and glucose biosensors make feasible the concept of using glucose biofuel cells to power low-powered biomedical devices [2,13,64].…”
