# Bending actuator apparatus and fabrication method

## Abstract

An apparatus includes an actuator body having an elongated shape with two end-caps on opposite ends, the actuator body defining a cavity within the actuator body, a first material extending between the two end-caps forming a first portion of a wall of the cavity; and a second material extending between the two end-caps, forming a second portion of the wall of the cavity, wherein the two materials have different mechanical responses to longitudinal and radial loading.
