“…It cannot be assumed that positive charge only in the oil contamination but small amount of negative charge also exists in it. Based on the triboelectric series (Molnar, Gersimov and Kurytnik, 2018), if a material is more likely to be positive side, it can be expected to push electrons from the negative side. By applying this concept, comparison is made between EPDM and oil contamination where movement of electron charge maybe lead to the occurrence of collision and the charge increase at the critical point.…”

A good polymer insulator can maintain the hydrophobic surface properties. However, polymer insulator is exposed to the environment which may lead to the deposition of rain water or factory oil. Oil is categorized as hydrophobic while water has a hydrophilic feature which when deposit on the insulator surface, it may affect the performance of insulator. Therefore, this paper studies the effect of water and oil contamination on current density and space charge distribution along 15 kV polymeric insulators particularly ethylene propylene-diene monomer (EPDM) and silicone rubber (SiR). A three-dimensional model of polymeric insulator was designed using a finite element software to evaluate the current density and space charge distribution while the experimental works was conducted in the laboratory to measure the charge distribution only. The results reveal that both current density and charge distribution is affected depend on the conductivity of contamination conditions. Both results extracted from simulation and experimental is in agreement where the EPDM insulator have higher amplitude of charge compared to SiR insulator.

“…This motion may be considered as the combination of two broadly known TEG modes, the vertical contact mode and the sliding mode. [2] It was executed thanks to a specially designed and 3D-printed moving pair of arms and holders which allowed the contact and sliding of one textile sample over the other.…”

“…Once the two triboelectric materials are forced into contact, charge flow appears between them, which leads to the development of an electric potential difference. [2] Meanwhile, of big interest is the use of textile materials in building TEGs, thanks to the unique textile properties they can offer like flexibility, [3,4] elasticity, [5] washability, [6][7][8] breathability, [8,9] bacterial resistance, [10] and comfort. [11] Additionally, a textile-based TEG may be an actual part of the body of a clothing item and not an additional piece of equipment.…”

Research on the triboelectric phenomenon and its use in so‐called triboelectric generators (TEG) has often led scientists to study the various parameters involved in the production of electricity induced by the contact and friction of textile structures. Although the use of textile materials and structures to build textile‐based TEGs is of particular interest, thanks to the advantages they can offer, however, the parameter of ambient humidity acts intensively on triboelectricity, affecting their electric power outcomes. This study investigates the performance of purely textile‐based materials used in a TEG measuring device which combines vertical and sliding modes as if they are part of a wearable garment. Six single jersey‐knitted textile samples, of identical yarn linear densities, are prepared. One material (para‐aramid) is used as the reference sample and it is paired with the rest (cotton, modal, polyester, wool, and acrylic). Consequently, five material combinations are available for measuring under various relative humidity conditions. Through these test series which reflect how a textile‐based TEG would operate under real conditions when embedded in a garment, the results reveal the big impact of ambient humidity on the triboelectric voltage outcome.

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.
