| description | A pump for a microfluidic device is disclosed. The pump comprises an actuator and a resilient isolator which is a planar, layered structure. The resilient isolator may comprise a support layer and optionally other layers for strengthening against tensile stress imposed by bending. Alternatively or in addition, the resilient isolator may comprise a plurality of annular regions, layers of the resilient isolator being configured such that at least one of the plurality of annular regions is less resistant than another one of the plurality of annular regions to bending. The actuator may comprise a piezoelectric disc including a surface which comprises electrode regions for electrical connection with respective conductive regions of a conductive layer of the resilient isolator, and an alignment feature for rotational alignment of the piezoelectric disc to ensure the electrical connection between the electrode regions and the respective conductive regions. |
