“…In addition to serving as a thermoelectric, Ag NWs/PEDOT:PSS composites as functional layers, coatings or components are widely applied in flexible organic solar cells, 150 supercapacitors, 151 electrodes, [152][153][154] and flexible sensors. 152,155 For instance, Yue et al 147 prepared transparent and conductive PEDOT:PSS/Ag NW/PEDOT:PSS three layer hybrid films by spin-coating. They exhibit a low sheet resistance of 21.9 O sq À1 and a high transmittance of 83.95% at 550 nm wavelength.…”

“…Functionalisation of PANI was applied to flexible sensors with the introduction of CeO 2 doped PANI [515], which improved the sensitivity 180% and the time response by 600 s to detect 30 ppm of NH 3 . The improved resistive performance of doped conductive polymers has been reported with the introduction of AgNW doped PEDOT:PSS [516]. The resulting sensor showed a 40% improvement of the maximum sensitivity with respect to pristine PEDOT:PSS in detecting NH 3 .…”

Flexible sensors have the potential to be seamlessly applied to soft and irregularly shaped surfaces such as the human skin or textile fabrics. This benefits conformability dependant applications including smart tattoos, artificial skins and soft robotics. Consequently, materials and structures for innovative flexible sensors, as well as their integration into systems, continue to be in the spotlight of research. This review outlines the current state of flexible sensor technologies and the impact of material developments on this field. Special attention is given to strain, temperature, chemical, light and electropotential sensors, as well as their respective applications.

The technological development of piezoelectric materials is crucial for developing wearable and flexible electromechanical devices. There are many inorganic materials with piezoelectric effects, such as piezoelectric ceramics, aluminum nitride, and zinc oxide. They all have very high piezoelectric coefficients and large piezoelectric response ranges. The characteristics of high hardness and low tenacity make inorganic piezoelectric materials unsuitable for flexible devices that require frequent bending. Polyvinylidene fluoride (PVDF) and its derivatives are the most popular materials used in flexible electromechanical devices in recent years and have high flexibility, high sensitivity, high ductility, and a certain piezoelectric coefficient. Owing to increasing the piezoelectric coefficient of PVDF, researchers are committed to optimizing PVDF materials and enhancing their polarity by a series of means to further improve their mechanical–electrical conversion efficiency. This paper reviews the latest PVDF-related optimization materials, related processing and polarization methods, and the applications of these materials such as those in wearable functional devices, chemical sensors, biosensors, and flexible actuator devices for flexible micro-electromechanical devices. We also discuss the challenges of wearable devices based on flexible piezoelectric polymer, consider where further practical applications could be.
