AI Article Synopsis
- The paper introduces a soft and inflatable tactile sensing balloon (SI-STSB) aimed at improving the diagnosis of colorectal polyps during colonoscopy by providing tactile feedback.
- It features a stretchable sensing layer that incorporates liquid metal in spiral microchannels, which enhances its sensitivity and functionality.
- Calibration experiments show that the SI-STSB displays excellent adjustable sensitivity and low hysteresis, indicating its potential to improve current diagnostic methods.
Article Abstract
In this paper, with the goal of addressing the lack of tactile feedback in colorectal cancer (CRC) polyps diagnosis using a colonoscopy procedure, we propose the design and fabrication of a novel soft and inflatable strain-based tactile sensing balloon (SI-STSB). The proposed soft sensor features a unique stretchable sensing layer - that utilizes a liquid metal injected within spiral-shape microchannels of a stretchable substrate - and is integrated with a unique inflatable balloon mechanism. The proposed SI-STSB has been thoroughly characterized through different calibration experiments. Results demonstrate a phenomenal adjustable sensitivity with low hysteresis behavior under different experimental conditions for this sensor making it a great candidate for enhancing the existing diagnosis procedures.

Modern techniques of rib fracture fixation surgery follow the AO principles of fracture reduction, fixation, and appropriate soft tissue handling. Fixation techniques can be performed using anatomic reduction and rigid fixation, or bridge plate fixation for comminuted fractures. Anatomic and nonanatomic plates can be used, although titanium precontoured locking plates are the most commonly used.

Thighplasty is a widely performed body contouring procedure, utilizing various surgical techniques for thigh lifting, including medial scar positioning, vertical and horizontal procedures, and liposuction. Despite its popularity, thighplasty is associated with high complication rates and suboptimal postoperative outcomes.This article presents a novel technique: the J medial thighplasty combined with helium plasma radiofrequency technology (HPRF) to address moderate skin and soft-tissue laxity and ptosis in the inner thighs.

Adhesion-switchable ultralow-hysteresis polymer ionogels are highly demanded in soft electronics to avoid debonding damage and signal distortion, yet the design and fabrication of such ionogels are challenging. Herein, we propose a novel method to design switchable adhesive ionogels by using binary ionic solvents with two opposite-affinity ionic components. The obtained ionogels exhibit moisture-induced phase separation, facilitating switchable adhesion with a high detaching efficiency (>99%).

Magnetic microrobots are significant platforms for targeted drug delivery, among which sperm-inspired types have attracted much attention due to their flexible undulation. However, mass production of sperm-like soft magnetic microrobots with high-speed propulsion is still challenging due to the need of more reasonable structure design and facile fabrication. Herein, a novel strategy is proposed for large-scale preparation of microalgae-based soft microrobots with a fully magnetic head-to-tail structure, called AlgaeSperm with robust propulsion and chemo-photothermal performance.

Hepatic steatosis/non-alcoholic fatty liver disease is a major public health delinquent caused by the excess deposition of lipid into lipid droplets (LDs) as well as metabolic dysregulation. Hepatic cells buildup with more fat molecules when a person takes high fat diet that is excessive than the body can handle. At present, millions of people in the world are affected by this problem.
