Abstract

A device may include a base plate and a deformable diaphragm having a first surface, where the first surface includes a textured surface. The device may also include a fluid chamber defined between the base plate and the deformable diaphragm, with the fluid chamber being in fluidic connection with the fluid reservoir and with the inflatable member. The device may also include a piezoelectric element having a second surface, the first surface of the deformable diaphragm and the second surface of the piezoelectric element being adhesively attached, the piezoelectric element being operable to repeatedly change a volume of the fluid chamber by deforming the deformable diaphragm to pump fluid from the reservoir to the inflatable member.
