About
Eiji Higurashi is a pioneering researcher at the intersection of micro-optics, robotics, and advanced semiconductor integration. His work is defined by two major thrusts: developing miniaturized optical sensors for robotic tactile feedback and pioneering multi-layer stacked CMOS image sensor architectures. Higurashi’s most impactful contribution is the creation of a micro-laser Doppler velocimeter (μ-LDV) that is 1/10,000th the volume of commercial devices, enabling it to be mounted on a robot hand. As detailed in his highly cited 2018 paper (28 citations), this sensor detects minute surface slip velocities, allowing for real-time grasping force control—a critical advance for dexterous robotic manipulation. He has also developed innovative two-axial shearing force sensors using optical chips and elastic frames. In the domain of imaging, Higurashi achieved a world-first by developing pixel-parallel three-layer stacked CMOS image sensors using double-sided hybrid bonding of SOI wafers (2023, 9 citations). This breakthrough, which enables both face-to-face and face-to-back bonding, paves the way for ultra-compact, high-performance computational cameras. With a career spanning from precision tactile sensors to next-generation 3D-stacked imagers, Higurashi’s work is foundational for the future of intelligent robotics and advanced vision systems.
