“…Ionic Polymer Metal Composites (IPMC), a type of Electro Active Polymer can be a choice for an integrated actuator-sensor system (Yamakita et al, 2006) and energy harvesting (Aureli et al, 2009), vibration control (Tiwari, 2012) for tactile and impact sensing (Bonomo et al, 2008; Chen et al, 2010) due to their fast response, large displacement, low maintenance, operation in both air and water, compliance, durability, (Cho and Lee, 2009; Tiwari et al, 2012) and lightness and softness (Biswal et al, 2014; Graziani et al, 2010). Ganley et al (2011) discussed that the ease of microfabrication, no separate packaging for air or water operation, and the minimal structural complexity make IPMC very suitable as actuators and sensors.…”

In this paper, an in-depth analysis of IPMC (ionic polymer metal composite) as sensors is performed, motivated by application to flapping wing micro air vehicles. The effect of water uptake for different IPMC samples reveals a correlation between IPMC metal content and water uptake. The effect of introducing a mass to the end of High-frequency IPMC (HFI ∼ 20.9 Hz) sensor shows an improvement in the IPMC sensing behavior, whereas, for the Low-frequency IPMC (LFI ∼ 8.9 Hz) sensor, there is a reverse trend. Gold (Au) coating on an HFI sensor results in a decrease in resonant frequency. Different mass loaded on the Au coated HFI beams reveals that the pre-bending by adding end mass to HFI sensor is beneficial up to a specific mass level, after which the sensing voltage decreases. The optimized mass loading for the Au coated HFI is determined.

The importance of electrode/polymer interface in the electro-mechanical properties of Ionic Polymer Metal Composite has been more and more emphasized in recent years. Among the various interface characterizations, this paper primarily focuses on the rough landscape between the bulk electrode and the ionic polymer. A series of geometrical models were established for the interface in the mass transport model of IPMC, based on actual profiles, flat line, Koch curves and Weirstrass–Mandelbrot (W–M) function curves, among which the results based on W–M function curves show best consistency with those based on actual profiles. Besides, methods to obtain the core parameters used in W–M function were investigated and an empirical formula was acquired. Finally the dependence of the interface roughness on the fabrication procedures as well as its influence on the capacitance and the electro-active displacement were also explored based on W–M parameters.

“…The sensing nature of IPMCs is of particular interest for the design and development of smart sensors [12,13,19] in applications such as energy harvesting [14][15][16][17]21], structural health monitoring [18], integrated sensor and actuator system [20], vibration control, tactile sensor [22,23] and impact sensors [24]. IPMCs as sensors have the advantages of compliance, long operating life, underwater applications, fast response and low maintenance.…”

To cite this article: Rashi Tiwari (2012) Ionic polymer-metal composite mechanoelectric transduction: effect of impedance, International Journal of Smart and Nano Materials, 3:4, 275-295, DOI: 10.1080/19475411.2012 Ionic polymer-metal composites (IPMCs) are commonly used as soft actuators due to their electromechanical response. However, the reverse phenomenon, i.e. IPMC's ability to generate charge on application of mechanical strain (mechanoelectric response), is not very well understood. The concept of mechanoelectric transduction and its dependence on complex IPMC architecture comprising of electrode, polymer and composite layer is illustrated with a phenomenological model. The impedance model takes into account the charge transport inside the polymer and layer properties in terms of their impedances. The model lucidly indicates the significance of capacitance in IPMC transduction. The impedance model is used for studying IPMC step and frequency response and the effect of IPMC capacitance on its application as energy harvester.
