Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

Advanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

TacScope: A Miniaturized Vision‐Based Tactile Sensor for Surgical Applications

Advanced Robotics Research, EarlyView.
TacScope is a compact, vision‐based tactile sensor designed for robot‐assisted surgery. By leveraging a curved elastomer surface with pressure‐sensitive particle redistribution, it captures high‐resolution 3D tactile feedback. TacScope enables accurate tumor detection and shape classification beneath soft tissue phantoms, offering a scalable, low‐cost ...

Stiffness after Rotator Cuff Repair

2021
Postoperative stiffness after rotator cuff repair can be functionally debilitating and lead to significant patient dissatisfaction. Both non-modifiable and modifiable patient risk factors can play a role in the development of significant postsurgical stiffness.

Knee muscle contributions to joint rotational stiffness

Human Movement Science, 2012
The purpose of this paper was to investigate total joint rotational stiffness (JRS) and relative muscle contributions to JRS with varying extensor moment demands. It was hypothesized that greater co-activation of the flexors at lower levels of moment would result in greater JRS, relative to moment demands.

Shoulder stiffness after rotator cuff repair: the fate of stiff shoulders up to 9 years after rotator cuff repair

Journal of Shoulder and Elbow Surgery, 2020
Stiffness and retear are 2 common complications of rotator cuff repair. McNamara et al found that postoperative stiffness was associated with lower retear rates at 6 months. This study aimed to determine if stiffness after rotator cuff repair protects the individual from retear up to 9 years after surgery.Two groups of patients, 69 with stiff and 63 ...

Rotational laxity and stiffness of the radiocarpal joint

Clinical Biomechanics, 1996
OBJECTIVE: To investigate the constraint and potential mechanism of torque transmission across the wrist joint. DESIGN: In vitro experiment using human cadaveric specimens. BACKGROUND: Transmission of torque from the forearm to the hand requires rotational stability at the wrist.

Prediction of Shoulder Stiffness After Arthroscopic Rotator Cuff Repair

The American Journal of Sports Medicine, 2021
Background: Postoperative shoulder stiffness (POSS) is a prevalent adverse event after arthroscopic rotator cuff repair (ARCR) that is associated with major limitations in everyday activities and prolonged rehabilitation. Purpose/Hypothesis: The purpose was to develop a predictive model for determining the risk of POSS within 6 months after primary ...
