In this paper we discuss a prototype ultra-lightweight membrane mirror based upon a previously developed linear peristaltic actuator (LPA). The LPA, consisting of an open-cell polymer foam substrate infused with magneto-rheological fluid (MRF), was inspired by the paradigm of peristalsis in nature. The prototype ultra-lightweight mirror consists of an opencell polymer foam substrate infused with MRF. To one side of the foam substrate resides several magnets, such that the surface figure of thedoi:10.2514/6.2010-2910 fatcat:kgazm3l37rcvdg4pywsr7vruhi
