Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

An Ultra-High-Quality Factor Silicon Disk Resonator

, 2019
A disk resonator demonstrates an ultra-high-quality factor (Q ∼ 107) at room temperature. When embedded in a board-level feedback oscillator an excellent short-term stability (340 ppt @ 1s integration time) is measured. The use of a new higher-order bulk

Design and Modeling of a High‐Displacement, Skin‐Integrated Flexible Electromagnetic Actuator for Haptic Interfaces in Virtual Reality

Advanced Robotics Research, EarlyView.
A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...

Designing MEMS Disk Resonator Based Biological Mass Sensors Under Fabrication Uncertainty

, 2009
A radial-contour mode disk resonator has its own advantages, less energy loss and less airflow damping, over existing counterparts such as surface acoustic wave (SAW) resonators and quartz crystal microbalance (QCM) sensors.

Piezo2 Mediates a Vicious Cycle of “Mechanical Homeostasis Imbalance—Inflammation” in Sensory Nerves and the Cartilage Endplate

Advanced Science, EarlyView.
In a lumbar spine instability model, dorsal root ganglion cells mediate the perception of relevant mechanical stresses through Piezo2 and subsequently release CGRP. CGRP activates the NF‐κB signaling pathway in cartilage endplate cells through the receptor RAMP1.

Decoupling of a Disk Resonator From Linear Acceleration Via Mass Matrix Perturbation [PDF]

, 2012
Axisymmetric microelectromechanical (MEM) vibratory rate gyroscopes are designed so the central post which attaches the resonator to the sensor case is a nodal point of the two Coriolis-coupled modes that are exploited for angular rate sensing.
