Silicone elastomers are promising materials for dielectric elastomer transducers (DETs) due to their superior properties such as high efﬁciency, reliability and fast response times. DETs consist of thin elastomer ﬁlms sandwiched between compliant electrodes, and they consti- tute an interesting class of transducer due to their inherent lightweight and potentially large strains. For the ﬁeld to progress towards industrial implementation, a leap in material devel- opment is required, speciﬁcally targeting longer lifetime and higher energy densities to provide more efﬁcient transduction at lower driving voltages. In this review, the current state of sili- cone elastomers for DETs is summarised and critically discussed, including commercial elastomers, composites, polymer blends, grafted elastomers and complex network structures. For future developments in the ﬁeld it is essential that all aspects of the elastomer are taken into account, namely dielectric losses, life- time and the very often ignored polymer network integrity and stability.
