Gecko‐Inspired Adhesive Grasping from Convex to Flat Surfaces with Contact Sensing by Liuwei Wang, JiaPeng Xie, Shuangjie Wang, Zhiyuan Weng, Yi Song, Zhendong Dai, Zhouyi Wang

“…The rolling module developed using four‐bar linkage mechanism allows the opposing bio‐toes to roll inward to enhance adhesion (adhesion forces up to 6.3 N on a flat surface and 23 N on an 18 m−1 curved surface) and roll outward to decrease the force in releasing (less than 3 N and especially less than 0.8 N on the flat surface). Embedded resistive strain gauges provide real time signals for the controller to determine the status of the bio‐toe, such as bending, adhesion/release, and even adhesive contact rates, thereby allowing the gripper to autonomously approach, envelop, adhere to, and release objects of various shapes, with the potential for dynamic adhesion control in the future. …”

An analysis of contact time of children’s walking gait with progressive backpack weight and selected duration conditions by Rawat Sukanya, Husain Rabiya, Shaw Dhananjoy

“…Study aim: Backpack carriage is a daily necessity for school-going children, but excessive loads and prolonged carrying durations may disrupt gait mechanics, potentially leading to musculoskeletal strain. The present study aimed to analyse the effect of progressive backpack weights and carrying durations on the contact time during the walking gait of school-aged boys. …”

DIAGNOSTICS OF META-INSTABLE STATE OF SEISMICALLY ACTIVE FAULT by S. A. Bornyakov, Jin Ма, A. I. Miroshnichenko, Yanshuang Guo, D. V. Salko, F. L. Zuev

“…In the first stage the offset begins in slow stationary mode with slow stresses relaxation on contact between blocks. In the second stage of the “accelerated synergies” strain rate increases and, subsequently, the deformation process through a process of self-organization came to dynamic impulse offset. …”

Microfiber epidermal thermometer (MET) with extraordinary high precision designed for long-term use on hairy skin by Adeela Hanif, Junho Park, Dohui Kim, Jangwon Yoon, Unyong Jeong, Dong Sung Kim

“…MET utilizes a stretchable fiber (~340 µm diameter), smaller than average hair follicle spacing, enabling conformal contact without interference from growing hair. Localized nanofiber reinforcement on a microfiber and temperature-sensing layer on localized region create a strain-engineered architecture, allowing MET to achieve strain-insensitive temperature detection. …”
