EXPERIMENTAL INVESTIGATION OF OPEN LOOP MULTI-STAGE IMPEDANCE PUMPING SYSTEM [PDF]
Journal of Engineering Science and Technology, 2011 Impedance pump is a simple valveless pumping mechanism, where an elastic tube is joined to a more rigid one; a periodic asymmetrical pinching on the elastic tube will produce a unidirectional flow.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, Volume 38, Issue 60, 27 October 2026.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

Functional Morphology of the Cardiac Jelly in the Tubular Heart of Vertebrate Embryos
Journal of Cardiovascular Development and Disease, 2019 The early embryonic heart is a multi-layered tube consisting of (1) an outer myocardial tube; (2) an inner endocardial tube; and (3) an extracellular matrix layer interposed between the myocardium and endocardium, called “cardiac jelly” (CJ).

Advanced Engineering Materials, Volume 27, Issue 20, October 2025.The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
