“…In addition to being able to undergo shape changing under an electric field, some IPMCs can generate voltage under deformation, which makes them a potential sensor (Figure 16d). An IPMCs based heart rate monitoring sensor was first explored by Chattaraj et al [115]. The mechanical impact induced by pulsating blood flow generates a potential difference on the metal plate electrode.…”

The booming wearable market and recent advances in material science has led to the rapid development of the various wearable sensors, actuators, and devices that can be worn, embedded in fabric, accessorized, or tattooed directly onto the skin. Wearable actuators, a subcategory of wearable technology, have attracted enormous interest from researchers in various disciplines and many wearable actuators and devices have been developed in the past few decades to assist and improve people’s everyday lives. In this paper, we review the actuation mechanisms, structures, applications, and limitations of recently developed wearable actuators including pneumatic and hydraulic actuators, shape memory alloys and polymers, thermal and hygroscopic materials, dielectric elastomers, ionic and conducting polymers, piezoelectric actuators, electromagnetic actuators, liquid crystal elastomers, etc. Examples of recent applications such as wearable soft robots, haptic devices, and personal thermal regulation textiles are highlighted. Finally, we point out the current bottleneck and suggest the prospective future research directions for wearable actuators.

IPMC is a new type of polymer material that will act violently to the stimulation of electrical signals. IPMC has changed the traditional mechanical driving mode. However, the development of IPMC is limited by factors like manufacture cost. In order to reduce the manufacture cost of IPMC, improve the output displacement and output force of IPMC, and make IPMC closer to real life, in this paper, we use carbon nanotubes to modify the ion exchange membrane of IPMC, and PDDA to modify carbon nanotubes and graphene. A graphite plated electrode and a carbon nanotube electrode were coated on a platinum plated IPMC. The common modified Pt-IPMC, carbon nanotubes modified Pt-IPMC, carbon nanotubes modified GS-IPMC, and carbon nanotubes modified CNT-IPMC were prepared. Through the experiment, it is found that the maximum output displacement of GS-IPMC modified by carbon nanotubes is 4.9 mm, and the maximum output force is 39 mN. The output displacement of ordinary Pt IPMC is 3.18 mm and the maximum output force is 31 mN. The maximum displacement and output force of GS-IPMC modified by CNTs are higher than those of Pt IPMC, which is more suitable for research and application.
