Abstract

Development of massage therapy as a non-invasive efficient technique, is hindered by the lack of standardized pressure metrics and accessibility challenges, demanding advanced sensors tailored for therapeutic applications. A hydrogel-based capacitive sensor is developed using poly(vinyl alcohol) (PVA) and cupric sulfate, which exhibits low energy dissipation (15.32 %) at 1 MPa and high sensitivity (49.12 MPa⁻¹ at 0–0.1 MPa, 17.96 MPa⁻¹ at 0.1–0.3 MPa, 10.03 MPa⁻¹ at 0.3–0.6 MPa, 4.11 MPa⁻¹ at 0.6–1 MPa) by leveraging the Hoffmeister effect and a dual-enhancement strategy combining surface micro roughening and graphene integration. The sensor demonstrates speed-independent and viscoelasticity-resistant performance, enabling reliable pressure sensing for massage therapy applications.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
