Implantable drug delivery system: Frontiers of medicine‐engineering interdisciplinary

Interdisciplinary Medicine, EarlyView.
This review systematically summarizes the driving mechanisms of implantable on‐demand drug delivery systems (IDDS), including endogenous, exogenous, and closed‐loop strategies. It highlights the pivotal roles of flexible electronics and miniaturization in enhancing the tissue conformity and spatial adaptability.

A Novel Slit Lamp‐Based System for 3D Ultrasound of the Eye

Journal of Ultrasound in Medicine, EarlyView.
Objectives This study aims to develop and evaluate a novel slit‐lamp‐based system to acquire 3‐dimensional (3D) ultrasound volumes using conventional ultrasound probes. Methods A slit‐lamp adapter was 3D printed and connected with a linear actuator and graphical user interface (GUI) system to control movement and create volumes of 2‐dimensional scans ...

3D Surface Profiling via Direct End‐to‐End Regression With a Photonic Geometric Sensor

Laser &Photonics Reviews, EarlyView.
Measurements of microscale surface patterns are essential for quality control across semiconductor and biomedical industries, yet the development of miniaturized, intelligent systems remains constrained by the complexity and bulkiness of conventional benchtop metrology.

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Development and Experimental Validation of a Bistable SMA Active Grill Shutter Actuator

Macromolecular Symposia, EarlyView.
ABSTRACT This study explores the use of bistable shape memory alloy (SMA) actuators in active grille shutters (AGS) to improve vehicle aerodynamics. The actuator, designed for adaptive movement, was tested and refined to achieve a reliable 90° rotation.

Inertial‐Based LQG Control: A New Look at Inverted‐Pendulum Stabilization

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Linear‐quadratic Gaussian (LQG) control is a well‐established method for optimal control through state estimation, particularly in stabilizing an inverted pendulum on a cart. In standard laboratory setups, sensor redundancy enables direct measurement of configuration variables using displacement sensors and rotary encoders. However, in outdoor
