SEOUL, South Korea: Scientists uncover advanced manufacturing strategies for piezoelectric and triboelectric tactile sensors SEOUL, South Korea, Jan. 3, 2025 /PRNewswire/ — Piezoelectric and triboelectric tactile sensors are designed to convert mechanical stimuli into electrical signals, making them critical components in intelligent systems. Piezoelectric sensors leverage voltage generation through mechanical stress in non-centrosymmetric materials, such as quartz and polyvinylidene fluoride (PVDF), while triboelectric sensors operate on contact-induced charge transfer. Both sensor types offer unique advantages, including self-powered functionality and high sensitivity but also face challenges, such as material brittleness and environmental limitations.
