An hydraulically actuated isolated ventricle

Cardiovascular Research, 1974
An apparatus is described that hydraulically actuates an excised dog ventricle. Cam-operated pumps programme flow through the heart valves to approximate in-vivo blood flow. The intact valves and the tortuous ventricular surface provide the authentic mixing influences that are important for indicator dilution studies.

Novel Linear Hydraulic Actuator

ASME/BATH 2015 Symposium on Fluid Power and Motion Control, 2015
In the area of linear motion, infinite stroke only is provided by electric actuators today, until now there has been no hydraulic alternative. The novel linear hydraulic actuator consists of two double acting cylinders with a common piston rod. The working principle of this actuator for short movements is that at least one piston is connected to the ...

Hydraulically actuated artificial muscles

SPIE Proceedings, 2012
Hydraulic Artificial Muscles (HAMs) consisting of a polymer tube constrained by a nylon mesh are presented in this paper. Despite the actuation mechanism being similar to its popular counterpart, which are pneumatically actuated (PAM), HAMs have not been studied in depth.

Electrically Actuated Hydraulic Solids

Advanced Engineering Materials, 2016
The authors introduce a new class of electrically‐actuated soft materials. Electro‐active hydraulic solids (EAHSs) are comprised of numerous microscale phase change capsules embedded inside a conductive elastomer matrix which replicate traditional wax actuators in a massively parallel fashion.
