Abstract

A microjet actuator assembly for use within a capsule adapted for self-propulsion through an animal body, or other fluidic environment. The microjet actuator assembly may be adapted for use to aid in self-propulsion of the capsule, eject a fluid therapeutic agent into a region of an animal body from a capsule, and collect a tissue sample from an animal body to store it within a capsule while in vivo. The microject actuator has: a cavity, at least one wall of which comprises a deformable member and a second wall of which has an aperture; and a driver for activating the deformable member to deform and change a volume size of the cavity, causing a fluid within the volume to eject out through the aperture and/or enter through the aperture; wherein the cavity aperture is in communication with a fluidic environment, such as an animal gastrointestinal system, outside of a housing for the capsule, permitting the fluid to also pass out of this housing.
