Abstract
The paper extensively explores moisture-induced charge decay in tribo-materials, addressing charge generation fundamentals and overcoming strategies. Triboelectric effect and contact electrification models are discussed, with corona charging and hydro-charging as effective charge generation methods. Moisture-induced adverse effects, such as swelling and charge dissipation, are outlined. Electronegativity and dangling bonds' roles in charge traps are explored, along with the impact of functionalities on materials. Various strategies, including hydrophobic surfaces, crystalline phases, and water-reactive materials, are proposed to counter moisture effects. Tribo-materials are currently applied in energy, sensors, environment, and healthcare, with potential in smart skin sensors and implantable devices. Overcoming challenges, including high charge density and durability, can lead to breakthroughs, expanding applications to harsh environments like underwater and high temperatures. The paper explores moisture-induced charge decay in tribo-materials, discussing generation mechanisms, and mitigation strategies such as the triboelectric effect and contact electrification models. It examines moisture-induced adverse effects like swelling and charge dissipation, as well as the roles of electronegativity and dangling bonds. Proposed solutions encompass hydrophobic surfaces, crystalline phases, and water-reactive materials. Tribo-material applications in energy, sensors, and healthcare demonstrate promise, with potential advancements in smart skin sensors and implants. image
