“…Small molecular plasticizers, such as surfactants (Zonyl, 73 xylitol 74 Triton X-100 75 and so on ref. 76 and 77) and co-solvents could improve the processability or the work function in specific applications of PEDOT:PSS, and they may also significantly alter the mechanical properties.…”

“…The electrical conductivity is caused by the delocalized π-electrons within its chemical structure and the presence of sulfonated polystyrene (PSS). It was adopted due to its known electronic conduction, biocompatibility, high transparency (≥90%) and particularly for its mechanical flexibility (E ≃ 1.2 GPa) [16,17,18], making it suitable for either sensing or stimulating microstructures [31]. Moreover, previous studies suggest that this polymer can provide a gauge factor in the range of 0.48–17.8 [19,20,21].…”

“…The strain gauges were modelled assuming a linear isotropic and elastic material. Values reported in the literature were used for the Youngs Modulus (90 GPa, 2 GPa) and Poisson ratio (0.31, 0.35) of titanium (Ti) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), respectively [16,17,18,25].…”

“…Specifically, the optimization of the fabrication process of metal titanium (Ti) strain gauges and the investigation on an alternative material to improve the robustness and performance of the devices, are presented. Polymeric strain gauges using poly(3,4-ethylenedioxythiophene)(PEDOT:PSS) are investigated to exploit the well-known electronic conduction, high gauge factor, biocompatibility, high transparency and particularly mechanical flexibility of the material [16,17,18,19,20,21].…”

Organ-on-chip (OOC) is becoming the alternative tool to conventional in vitro screening. Heart-on-chip devices including microstructures for mechanical and electrical stimulation have been demonstrated to be advantageous to study structural organization and maturation of heart cells. This paper presents the development of metal and polymeric strain gauges for in situ monitoring of mechanical strain in the Cytostretch platform for heart-on-chip application. Specifically, the optimization of the fabrication process of metal titanium (Ti) strain gauges and the investigation on an alternative material to improve the robustness and performance of the devices are presented. The transduction behavior and functionality of the devices are successfully proven using a custom-made set-up. The devices showed resistance changes for the pressure range (0–3 kPa) used to stretch the membranes on which heart cells can be cultured. Relative resistance changes of approximately 0.008% and 1.2% for titanium and polymeric strain gauges are respectively reported for membrane deformations up to 5%. The results demonstrate that both conventional IC metals and polymeric materials can be implemented for sensing mechanical strain using robust microfabricated organ-on-chip devices.

“…However, reliably enhancing its conductivity remains challenging despite the decade-long research effort. [16,22,31,37,[39][40][41][42][43][44][45][46][47] Most of the studies focused on the improvement of the conductivity while the stretchability was less investigated. [48][49][50][51] Our group has recently shown the benefits of a polyethylene oxide (PEO) network within PEDOT:PSS for microactuators with an excellent electromechanical response.…”

The development of transparent, conducting, and stretchable poly(3,4-ethy lenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)-based electrodes using a combination of a polyethylene oxide (PEO) polymer network and the surfactant Zonyl is reported. The latter improves the ductility of PEDOT:PSS and enables its deposition on hydrophobic surfaces such as polydimethylsiloxane (PDMS) elastomers, while the presence of a 3D matrix offers high electrical conductivity, elasticity, and mechanical recoverability. The resulting electrode exhibits attractive properties such as high electrical conductivity of up to 1230 S cm −1 while maintaining high transparency of 95% at 550 nm. The potential of the electrode technology is demonstrated in indium-tin-oxide (ITO)-free solar cells using the PBDB-T-2F:IT-4F blend with a power conversion efficiency of 12.5%. The impact of repeated stretchand-release cycles on the electrical resistance is also examined in the effort to evaluate the properties of the electrodes. The interpenetrated morphology of the PEDOT:PSS and polyethylene oxide network is found to exhibit beneficial synergetic effects resulting in excellent mechanical stretchability and high electrical conductivity. By carefully tuning the amount of additives, the ability to detect small changes in electrical resistance as a function of mechanical deformation is demonstrated, which enables the demonstration of stretchable and resilient on-skin strain sensors capable of detecting small motions of the finger.
