IPMC actuators composites

Experiments were conducted to measure the stiffness of an IPMC beam and two IPMC-PVDF composite beams with different insulating layer thickness (30 pm vs. 100 pm). The two composite beams were named IPMC/PVDFl and IPMC/PVDF2, respectively. As illustrated in Fig. 8.5(a), the cantilevered beam under measurement was pushed quasi-statically at the tip by a linear actuator. Between the linear actuator and the tip was a PVDF-based micro force sensor measuring the interaction force. The tip displacement was measured with a laser distance sensor. Fig. 8.5(b) shows the measured tip displacement together with the corresponding force for each beam, with the spring constants determined to...

In this chapter, the fundamental aspects of the ionic polymer-metal composite (IPMC) actuators have been described. The IPMC actuators have many unique characteristics such as softness, large bending response, low voltage drive, easy forming into any shape, and so on, which are suitable for biomedical applications. In the next chapter, the biomedical applications of IPMC actuators are described.

This chapter describes how to start experiments with ionic polymer-metal composite (IPMC) actuators. In the first part, a fabrication of IPMC actuator element is summarized. In the next part, how to setup a measurement system of IPMC actuator and test the actuator performance is described. In the last part, a control method of IPMC actuator is discussed. From the information in this chapter, experiments with IPMC actuators can be started.

Ionic Polymeric Metallic Composites (IPMCs) are a class of EAPs that exhibit characteristics of both actuators and sensors, Shahinpoor et al. [6—11]. The flexibility of an IPMC makes it possible to be applied both in small and large deflection applications. Successive photographs of an IPMC strip are shown in Fig. 2.1 that demonstrates very large deformation (up to 8 cm) in the presence of low voltage. The sample is 10 mm wide, 80 mm long, and 0.34 mm thick. The time interval is 1 s and the actuation voltage is 4 V DC. 

The purpose of this book is to provide a focused, in-depth, yet self-contained treatment of recent advances made in several most promising EAP materials. In particular, the book covers two classes of ionic EAPs, ionic polymer-metal composites (IPMCs) and conjugated polymers, and one class of electronic EAP materials, dielectric elastomers. Ionic EAPs realize actuation through ion transport, and thus require very low voltages (a few volts) to operate, but their bandwidths are typically lower than tens of Hz. On the other hand, dielectric elastomers rely on electrostatic forces to operate and thus require high actuation voltages (kilovolts), but...
