“…When the fabric was stretched, the resistance first slightly increased and then decreased forming a peak. This phenomenon also occurred during the strain release process forming the second peak, and it has also been reported by P. Calvert et al [34]. The formation of this double peak might be attributed to the slow strain recovery of the fabric at large elongation [34], which is consistent with the hysteresis between the elongation and relaxation induced in the strain stress curves (Fig.…”

, GG (2012), Polypyrrole coated nylon lycra fabric as stretchable electrode for supercapacitor applications, Electrochimica Acta, 68, Polypyrrole coated nylon lycra fabric as stretchable electrode for supercapacitor applications AbstractWearable electronics offer the combined advantages of both electronics and fabrics. Being an indispensable part of these electronics, lightweight, stretchable and wearable power sources are strongly demanded. Here we describe a daily-used nylon lycra fabric coated with polypyrrole as electrode for stretchable supercapacitors. Polypyrrole was synthesized on the fabric via a simple chemical polymerization process with ammonium persulfate (APS) as an oxidant and naphthalene-2,6-disulfonic acid disodium salt (Na 2 NDS) as a dopant. This material was characterized with FESEM, FTIR, tensile stress, and studied as a supercapacitor electrode in 1.0 M NaCl. This conductive textile could endure 1000 stretching cycles with 100% strain applied, and still retained its electrical conductivity and electrochemical properties. Interestingly, we also found that this material showed improved electrochemical properties when it was being stretched. ABSTRACTWearable electronics offer the combined advantages of both electronics and fabrics.

“…The inkjet printing system includes a custom made inkjet driver and has been described previously. [25][26][27][28] In brief, a cartridge refi lled with the PEDOT:PSS ink was mounted on the arm of a robotic Automove system (Asymtek, Carlsbad, CA) that was connected with and controlled by a computer to move in desired patterns. Fabrics to be printed were placed on a z -direction adjustable table underneath the cartridge.…”

“…In Ref. [22], a sensor based on PEDOT:PSS is adopted to measure the bending angle of knee flexion and wrist rotation. The results suggest that bending sensors fabricated by inkjet printing adopting PEDOT:PSS or silver nanoparticles ink offer many advantages with respect to other systems for human movement monitoring (inside and outside the human body), such as, the small footprint, low cost and versatility.…”

a b s t r a c tRecently, inkjet printing technology has received growing attention as a method to produce low-cost large-area electronics, sensors, and antennas on polymer substrates. This technology relies on printing techniques to deposit electrically functional materials onto polymer substrates to fabricate electronic components or sensing elements. In this paper, we applied an inkjet printed technology for the development and characterization of films on a polymer substrate aiming at giving design considerations for the optimization of strain sensors or printed electronics obtained by inkjet printing. Two inks were tested over a polyimide substrate, a water-based conductive polymer, PEDOT:PSS, and a silver nanoparticles ink. Their sensing capabilities were investigated under tensile conditions and various strain histories (strain ramp; cyclic loading-unloading tests; application of constant strain over prolonged time) aiming at highlighting the correlation between electrical response, applied strain, time and mechanical histories. Furthermore, the mechanical viscoelastic response of the substrate was investigated under similar strain histories interpreting the results at the light of the substrate deformational characteristics and evaluating its influence.
