About

Yuji Arinaga is a researcher in precision engineering and robotics, specializing in torque sensing and microdisplacement measurement technologies. His key contributions center on developing compact, high-sensitivity torque measurement devices for robotic systems, particularly for integration into robot arms. His most cited work, "Torque Measurement Device Using an Integrated Microdisplacement Sensor" (2013), introduces a novel design that combines a trapezoidal frame with an optical microdisplacement sensor. The device measures torque by detecting minute mirror tilt angles on the frame’s underside—achieving a sensor tip area of just 3 mm² and thickness of 0.7 mm. This innovation enables precise, non-contact torque sensing in constrained spaces, addressing critical needs in robotic force control and safety. While his citation count (3) reflects a focused, early-stage impact, Arinaga’s work demonstrates a strong foundation in micro-electromechanical systems (MEMS) and embedded sensing. His research bridges mechanical design and optical measurement, offering practical solutions for next-generation robotic joints and haptic interfaces. Arinaga’s contributions are particularly valuable for students and engineers exploring miniaturized, high-resolution torque sensors in automation and human-robot interaction.
