20.500.12556/RUL-167554 OptoSkin novel LIDAR touch sensors for detection of touch and pressure within wave guides Light Detection and Ranging (LIDAR) sensors, employing direct Time-of-Flight (dTOF) measurements, are crucial for precise surface localization and are increasingly integrated into compact chip designs. These sensors have extensive use in proximity sensing in various applications. This paper presents the innovative use of LIDAR sensors for ranging within wave guides to accurately detect touch and pressure. In our OptoSkin sensors, light propagates via total internal reflection (TIR) within the wave guide. Then it is reflected back to the sensor as a result of wave guide deformation and/or scattering in the contact area, a phenomenon attributed to frustrated total internal reflection (FTIR). We have designed, simulated, and implemented different OptoSkin sensors using wave guides constructed from a flexible rod, rigid curved 3D printed resin, and planar soft silicone rubber, respectively. Each configuration is equipped with multiple LIDAR sensors, demonstrating effective localization of touch points. In addition, pressure sensing was performed on the elastic wave guides. These novel touch sensors show great potential for applications such as robotic sensor skins, which enhance tactile responsiveness and interaction. sensors optical sensors tactile sensors optical scattering optical reflection optical refraction optical fiber sensors light detection and ranging LIDAR Time-of-Flight TOF touch detection tactile sensing frustrated total internal reflection FTIR wave guide light guide optical sensing robotic sensor skin proximity sensing senzorji optični senzorji taktilni senzorji optično sipanje optični odboj optični lom senzorji z optičnim vlaknom detekcija svetlobe in razdalje Lidar čas potovanja TOF zaznavanje dotika taktilno zaznavanje popolni notranji odboj optično vodilo svetlobno vodilo optično zaznavanje robotska senzorna koža zaznavanje bližine true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-27 13:51:28 2025-02-27 13:51:33 2025-02-28 04:00:11 0000-00-00 00:00:00 2024 0 0 Str. 33268-33280 iss. 20 Vol. 24 Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 681.586.5:007.52 1530-437X 10.1109/JSEN.2024.3443615 207028227 OptoSkin_Novel_LIDAR_Touch_Sensors_for_Detection_of_Touch_and_Pressure_Within_Wave_Guides.pdf OptoSkin_Novel_LIDAR_Touch_Sensors_for_Detection_of_Touch_and_Pressure_Within_Wave_Guides.pdf 1 CDFB5245A2A9A1D7E6FDDF964B55D9F8 d68db7f1f29ec385df87bf36304f62e6aeb39d7da78bde99dd0c281f405e0ece f58fee89-f508-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200191 https://ieeexplore.ieee.org/document/10643001 1 a792df5f-f508-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200190 Fakulteta za elektrotehniko 0 0 0
