6 April 2009Peristaltic pump made of dielectric elastomer actuators
The functional principle of peristaltic motion is inspired by the pattern in which hollow organs move. The technology of
dielectric elastomer actuators provides the possibility to design a very compact peristaltic pump. The geometries of the
whole pump and the actuator elements have been determined by numerical simulations of the mechanical behaviour and
the fluid dynamics. With eight independent actuators the pumping channel is self-sealing and there is no need for any
valves. The first generation of this pump is able to generate flow rates up to 0.36 μl/min.
