Abstract: The invention provides a shape change device (20) utilising a plurality of particles (28) of electroactive polymer material embedded within a compliant material matrix (24) and adapted to deform in response to application of an electrical stimulus. A resultant shape-change of the compliant matrix enables realisation of a particular deformation profile across a surface of the compliant material. Particles are stimulated in plural groups by one or more arrangements of electrodes (34). Shapes, sizes, dimensionalities and locations of stimulated EAP particle regions may be selectively chosen to initiate a particular response in the material, and produce a particular desired deformation profile across the material surface.

Abstract: A nozzle (12) for an oral irrigator device (10) having a guidance tip (34) with at least one orifice (36) at one end, and a nozzle spacer assembly (58) positioned around the at least one orifice (36). The at least one orifice is configured to expel a fluid as one of a jet, a spray, or any combination thereof. The nozzle spacer assembly (58) comprises at least two pairs of pliable spacers (60) that extend from the surface (35) for ensuring that the area at an entrance of an interproximal space between two teeth are treated, and (ii) establishing an improved angle of impact of the fluid expelled from the orifice.
