“…Similar electrochemical responses and subsequent conclusion to those here exposed were obtained from films of conducting polymers (Conzuelo et al, 2010;Otero et al, 2012a;Martinez, 2013a,b, 2015) or graphene (Martínez et al, 2012). The presence of chemical reactions gives for the empirical reaction rates the expected semilogarithmic or double-logarithmic relationships for the studied experimental variables.…”

The nature of the electrochemical responses from carbon nanotubes (CNTs), capacitive (physical), or Faradaic (chemical, also named p-doping or n-doping) remain controversial. In this chapter, the literature is reviewed and discussed trying to elucidate if some of the two processes prevails, how the presence of chemical reactions can be elucidated and which properties, specific from the chemical processes, can be exploited. Different electrochemical responses and theories trying to explain those responses are discussed. The separation and quantification methodologies of the capacitive and Faradaic components involved in some electrochemical responses from CNTs are presented.

“…Since the working potential of PPy/DBS films can change as a function of electrolyte concentration, temperature or mechanical stress, it is hypothesized that the material can act not only as an actuator but also as an environmental sensor [56]. Artificial muscles, as electrochemical actuators made up of reactive materials, can therefore respond to the ambient conditions during actuation.…”

Abstract:Organic bioelectronics forms the basis of conductive polymer tools with great potential for application in biomedical science and medicine. It is a rapidly growing field of both academic and industrial interest since conductive polymers bridge the gap between electronics and biology by being electronically and ionically conductive. This feature can be employed in numerous ways by choosing the right polyelectrolyte system and tuning its properties towards the intended application. This review highlights how active organic bioelectronic surfaces can be used to control cell attachment and release as well as to trigger cell signaling by means of electrical, chemical or mechanical actuation. Furthermore, we report on the unique properties of conductive polymers that make them outstanding materials for labeled or label-free biosensors. Techniques for electronically controlled ion transport in organic bioelectronic devices are introduced, and examples are provided to illustrate their use in self-regulated medical devices. Organic bioelectronics have great potential to become a primary platform in future bioelectronics. We therefore introduce current applications that will aid in the development of advanced in vitro systems for biomedical science and of automated systems for applications in neuroscience, cell biology and infection biology. Considering this broad spectrum of applications, organic bioelectronics could lead to timely detection of disease, and facilitate the use of remote and personalized medicine. As such, organic bioelectronics might contribute to efficient healthcare and reduced hospitalization times for patients. OPEN ACCESSElectronics 2015, 4 880

“…The PPyDBS linear actuator was characterized following the linear length evolution with the consumed electrical charge during redox reaction(coulodynamic responses, l/Q) [15][16][17][18]. The PPyDBS film was submitted to consecutive square potential wave, getting the chronoamperometric responses) from -1V to +1V in PC-Tf and from -0.8V to +0.8V in Aq-TM.…”

Free standing conducting polymer films based on polypyrrole doped with dodecylbenzoesulfate (PPyDBS) are investigated in TBACF 3 SO 3 (tetrabutylammonium trifluoromethanesulfonate) propylene carbonate (PC-Tf) followed in aqueous TMACl tetramethylammonium chloride (Aq-TM) with the aim to investigate actuation properties (anion or cation-driven actuation). Under isometric (constant force) conditions ECMD (electro-chemo-mechanical deformation) measurements are performed during cyclic voltammetric and chronoamperometric experiments. Electrolyte and solvent effects revealing that the actuation direction in propylene carbonate electrolyte changed from expansion at anodic potential to expansion at cathodic potentials during square wave potential steps. Finally if the PPyDBS film immersed in aqueous electrolyte the anion-driven actuation properties are maintenance. SEM measurements are implemented to reefer changes in film morphology and ion content (EDX, energy dispersive X-Ray) before and after actuation.
