Fully 3D-Printed Soft Capacitive Sensor of High Toughness and Large Measurement Range.
Adv Sci (Weinh)

Soft capacitive sensors are widely utilized in wearable devices, flexible electronics, and soft robotics due to their high sensitivity. However, they may suffer delamination and/or debonding due to their low interfacial toughness. In addition, they usually exhibit a small measurement range resulting from their limited stiffness variation range.

Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri-implant health, and ensure long-term success. Traditionally, titanium stock healing abutments or chairside-customized abutments were used to shape peri-implant tissues and develop the emergence profile for implant-supported prostheses. However, advancements in digital dentistry now allow for more precise customization and increased treatment efficiency.

Key Laboratory of Underwater Acoustic Communication and Marine Information Technology of the Ministry of Education, College of Ocean and Earth Sciences, Xiamen University, Xiamen, China.
Aberration layers (AL) often present significant energy transmission barriers in microwave engineering, electromagnetic waves, and medical ultrasound. However, achieving broadband ultrasonic focusing through aberration layers like the human skull using conventional materials such as metals and elastomers has proven challenging. In this study, we introduce an inverse phase encoding method employing tunable soft metalens to penetrate heterogeneous aberration layers.

Article Synopsis
- The study showcases improvements in electrohydrodynamic (EHD) pumps alongside a new 3D-printable organohydrogel designed for soft robotics.
- Using advanced digital light processing (DLP) technology, the researchers created a manifold pump array that can generate 90.2 kPa of pressure and deliver a flow rate of 800 mL per minute, far exceeding the capabilities of traditional EHD systems.
- The novel organohydrogel developed has a low swelling ratio, high stretchability, and durability under stress, making it ideal for dynamic applications in soft robotics, bioengineering, and vertical farming.
