Soft Electromagnetic Actuator and Oscillator
This work presents a groundbreaking soft electromagnetic system capable of bistable actuation and self‐regulated oscillation. Using liquid metal and silicone as a compliant conductor, the actuator enables force generation, sensing, and feedback with minimal power.

The Heart of a Horse: 3‐D Echocardiographic Analysis of the Equine Aortic Valve [PDF]
Aortic regurgitation (AR) can be a normal function of aging or a disease in younger horses. Symptoms range from no outward signs to decreased performance to sudden cardiac arrest.

This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Apical access and closure devices for transapical transcatheter heart valve procedures. [PDF]
The majority of transcatheter aortic valve implantations, structural heart procedures and the newly developed transcatheter mitral valve repair and replacement are traditionally performed either through a transfemoral or a transapical access site ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

3D Wiring Microelectrodes in a PMMA Microfluidic Device by Vacuum Filling Method
This paper proposes a method for fabricating 3D wiring microelectrodes in arbitrary designs within 3D‐printed microfluidics. By attaching a PDMS lid and using vacuum filling, low‐melting‐point alloy (LMA) is introduced into microchannels. This enables the creation of 50 µm microelectrodes, including complex shapes.

Fluid dynamic characterization of a polymeric heart valve prototype (Poli-Valve) tested under continuous and pulsatile flow conditions. [PDF]
PURPOSE: Only mechanical and biological heart valve prostheses are currently commercially available. The former show longer durability but require anticoagulant therapy; the latter display better fluid dynamic behavior but do not have adequate durability.
