  • A Soft Pulsed Pump using A Snap Motor

抄録

<p>In this paper, a soft pump which carries fluid in a pulsated fashion is proposed. The proposed soft pump utilizes a snap motor which generates a snap-through buckling of an elastic strip for alternatively shrinking and expanding a soft bag with a pair of one-directional inflow and outflow ports. Due to impulsive motion of the snap motor, the pump can generate a pulsed flow of fluid. The experimental results using a prototype of the proposed soft pump shows that it can generate a very impulsive water flow repeatedly. While the efficiency of this first prototype is not so high thus far, this mechanically simple soft pump has a potential to be used as a propulsion mechanism for a compact underwater robot which swims like an octopus.</p>
