The field of stretchable electronics has recently gained significant interest from the academic community, with a focus on producing materials that demonstrate reliable electrical performance with improved response to mechanical deformation. This review highlights the recent progress in understanding the relationships between the mechanical behavior and electrical performance of such devices. Potential solutions can take the form of intrinsically elastic polymers, polymer semiconductor/ elastomer blends and alternative engineering-oriented approaches, which are discussed herein. Trends and design strategies are beginning to manifest in this early stage of the stretchable electronics field. The development of stretchable electrical systems can provide unique applications of organic electronics.

Thin film Carbon Nanotube (CNT) networks are used as a conductive, transparent and flexible electrode for electrochemically depositing a conducting polymer on it, polypyrrole or polyaniline in the present work. We analyse the properties of the device as an electrochemical sensor, measuring his pH dependence by recording the open circuit potential in various buffer solutions, ranging from pH 1 to 13. The results show a good sensitivity, linearity and stability in both cases. In the case of CNT/polyaniline, it can be used simply as an optical sensor, as the colour of polyaniline changes with pH. The CNT/polypyrrole and CNT/polyaniline devices could have applications as solid state gas sensor or biosensor deposited on any shape of surface that can be transparent and flexible.

“…Many of these materials, have already found applications as electronic devices [1][2][3] , sensors for electronic tongues 4,5 , selective membranes 6 , and rechargeable batteries 7 . Polypyrrole (PPy) is one of the most extensively studied conducting polymer due to its good electrical conductivity, environment stability, good solubility, redox properties and relative ease oxidation of the monomer (pyrrole).…”

Polypyrrole films have been electrochemically polymerized on platinum electrode under different conditions. The effect of the parameters used during the potentiostatic polymerization, such as monomer concentration, type of doping agent (i.e. counterion), deposition time (i.e. films thickness), concentration of doping agent and polymerization potential on the rate of growth and the electrochemical properties of the polymeric film has been studied. In addition, the effect of the sweep rate of polypyrrole films polymerized with several doping agents were investigated. The results show that the kinetic of formation, the shape, the peak intensity, the peak potential and the electrochemical stability of the electroactive polypyrrole film are reliant on the conditions used during the polymerization process. The empirical kinetics determined from the polymerization charge were found to depend on [Py] 0.85 and [SO 4 2-] 0.5 . The kinetic of the electrochemical response was also affected by the anion use as doping agent during the electrochemical synthesis.
