“…The authors also presented a comprehensive finite element analysis of the achievable stroke volumes in relation to electrode shape and pump chamber pressure. A multilayered process was used by the authors of [178] to fabricate a flap valve IPMC membrane micropump embedded in a PDMS structure. Their device achieved a maximum flow rate of *0.8 ml/min with an applied voltage of only 3 V at 3 Hz driving frequency (Fig.…”

Microfluidic devices have not yet evolved into commercial off-the-shelf products. Although highly integrated microfluidic structures, also known as lab-on-a-chip (LOC) and micrototal-analysis-system (lTAS) devices, have consistently been predicted to revolutionize biomedical assays and chemical synthesis, they have not entered the market as expected. Studies have identified a lack of standardization and integration as the main obstacles to commercial breakthrough. Soft microfluidics, the utilization of a broad spectrum of soft materials (i.e., polymers) for realization of microfluidic components, will make a significant contribution to the proclaimed growth of the LOC market. Recent advances in polymer science developing novel stimulus-active soft-matter materials may further increase the popularity and spreading of soft microfluidics. Stimulus-active polymers and composite materials change shape or exert mechanical force on surrounding fluids in response to electric, magnetic, light, thermal, or water/solvent stimuli. Specifically devised actuators based on these materials may have the potential to facilitate integration significantly and hence increase the operational advantage for the end-user while retaining costeffectiveness and ease of fabrication. This review gives an overview of available actuation concepts that are based on functional polymers and points out promising concepts and trends that may have the potential to promote the commercial success of microfluidics.

“…IPMCs can be used to couple high precision with high compliance to create a safe and accurate micromanipulation system. [47][48][49][50][51][52][53][54][55] IPMCs have built-in sensing and actuation capabilities. 46,56 In particular, they hold strong promise for versatile sensing applications because of their high sensitivity, inherent polarity and direct mechanosensory properties, which minimize the complexity in both the sensor construction and the signal processing.…”

In this paper, the authors present a comprehensive review of ionic polymer-metal composites (IPMCs) covering their fundamentals, fabrication processes, characterization and applications. IPMCs are becoming increasingly popular among scholars, engineers and scientists due to their inherent properties of low activation voltage, large bending strain -that is, the transformation of electrical energy to mechanical energy -and properties to be used as a bidirectional material -that is, they can be used as actuators and sensors. Among the diversity of electroactive

Smart systems adapt to the surrounding environments in a number of ways. They are capable to scavenge energy from available sources, sense and elaborate external stimuli and adequately react. Electro Active Polymers are playing a main role in the realization of smart systems for applications if fields such as bio inspired and autonomous robotics, medicine, and aerospace. This paper focus on the possibility to use Ionic Polymer Metal Composites as a class of materials relevant to the realization of post silicon smart systems. The three main aspects of this new technology, i.e., fabrication methods, modeling, and applications are described with emphasis to most recent results. Attention is given to main challenges and shortcomings to be solved for technology, modelling, and control of IPMC based devices that need to be solved before this new technology can be fully exploited in real world applications.
