“…[313] The most ideal location to place an energy harvester is near the diaphragm, which is the muscle that induces the contraction and relaxation of the lungs. The power output of the diaphragm is estimated to be 0.41 W. [104] The normal respiratory rate is 12-20 bpm for an adult at rest. [314,315] The energy harvested from the diaphragm could be used to power nearby devices such as a pacemaker or a subcutaneous drug delivery system.…”

Implantable and ingestible biomedical electronic devices can be useful tools for detecting physiological and pathophysiological signals, and providing treatments that cannot be done externally. However, one major challenge in the development of these devices is the limited lifetime of their power sources. The state-of-the-art of powering technologies for implantable and ingestible electronics is reviewed here. The structure and power requirements of implantable and ingestible biomedical electronics are described to guide the development of powering technologies. These powering technologies include novel batteries that can be used as both power sources and for energy storage, devices that can harvest energy from the human body, and devices that can receive and operate with energy transferred from exogenous sources. Furthermore, potential sources of mechanical, chemical, and electromagnetic energy present around common target locations of implantable and ingestible electronics are thoroughly analyzed; energy harvesting and transfer methods befitting each energy source are also discussed. Developing power sources that are safe, compact, and have high volumetric energy densities is essential for realizing long-term in-body biomedical electronics and for enabling a new era of personalized healthcare.

“…Piezoelectric energy harvesters are driven by mechanical energy that comes from ambient environments such as water kinetic, wind flow, and mechanical vibration is abundant. [26,94] Triggered by the external applied mechanical stress, polarization forms inside the piezoelectric materials. Such generated internal potential results in a potential difference across the material, which can either generate ROS for in situ water disinfection or lead to electric charges flowing through external circuits for ex situ treatment.…”

“…[19][20][21][22] Recently, several energy harvesting systems that can harness green energy sources such as wind, wave, vibrations, heat, and solar have been developed based on the mechanisms of triboelectric, piezoelectric, pyroelectric, and photovoltaic. [23][24][25][26][27] These devices are lightweight, low cost, easily applicable, and have high voltage outputs and high harnessing efficiency with lowfrequency stimuli. [28][29][30] Thus, they can drive microbial inactivation process without an external power supply; [21,31,32] during water disinfection, the harvester generates electrical energy, which is subsequently rectified and conditioned to drive the microbial inactivation process in water.…”

Contaminated drinking water is one of the main pathogen transmission pathways making waterborne illnesses such as diarrheal diseases and gastroenteritis a huge threat to public health, especially in the areas where sanitation facilities and gird power are inadequate such as rural and disaster hit areas. Self‐powered water disinfection systems are a promising solution in these cases. In this review paper, the authors provide an overview of the new and emerging methods of applying energy harvesting materials and devices as a source of power for water disinfection systems microbial disinfection in water by harnessing ambient forms of energy such as mechanical motion, light, and heat into electricity. The authors begin with a brief introduction of the different energy harvesting technologies commonly applied in water disinfection; triboelectric, piezoelectric, pyroelectric, and photovoltaic effects. Various microbial disinfection mechanisms and types of device construction are summarized. Then, a detailed discussion of the energy harvester‐driven water disinfection process is provided. Finally, challenges and perspectives regarding the future development of self‐powered water disinfection are described.

Triboelectric nanogenerators (TENGs), which operate in contactless mode and avoid physical contact, are highly attractive for self-powered sensor systems aiming to achieve long-term reliable operation and reduce rubbing friction. Herein, an ultra-flexible and high-performance contactless doublelayer TENG (CDL-TENG) is first designed and fabricated using a metalorganic framework-based cobalt nanoporous carbon (Co-NPC)/Ecoflex with MXene/Ecoflex nanocomposite layer for self-powered sensor applications. The porous structure of the Co-NPC provides a high-surface-area of the nanocomposite and the charge storage layer of the MXene/Ecoflex nanocomposite accumulates more negative charge to improve the functionality of the CDL-TENG two and three times, respectively. Compared with Ecoflex film-based TENGs, the fabricated CDL-TENG exhibits an eight-fold slower decay rate owing to charge trapping characteristics, which were confirmed by surface potential measurements. The CDL-TENG shows excellent humidity and acceleration sensitivity of about 0.3 V/% and 2.06 Vs 2 m −1 . The CDL-TENG also offers non-contact position detection performance in the 20 cm range. Furthermore, the CDL-TENG is successfully integrated with mobile-vehicles and an intelligent robot to perform obstacle and humanmotion detection. Finally, a contactless door-lock password authentication system was demonstrated. These multifunctional benefits make it useful for numerous applications, including artificial intelligence, human-machine interfaces, and self-powered sensors.
