“…Textiles that are smart enough to interpret user requirements based on the designed system and type of output can be categorized as smart textiles [1,2]. In recent years, the usage of electronic components in specifically designed smart textiles, also known as etextiles, has increased tremendously in various fields [3][4][5].…”

The development of specific user-based wearable smart textiles is gaining interest. The reliability and washability of e-textiles, especially electronic-based components of e-textiles, are under particular investigation nowadays. This is because e-textiles cannot be washed like normal textile products and washing electronic products is not common practice in our daily life. To adopt the e-textile products in our daily life, new standards, based on product usage, should be developed especially for flexibility and washability. The wearable motherboards are the main component for e-textile systems. They should be washing reliable and flexible for better adoption in the system. In this manuscript, flexible wearable PCBs were prepared with different conductive track widths and protected with silicone coatings. The samples were washed for 50 washing cycles in the household washing machine, and provoked damages were investigated. The PCBs were also investigated for bending tests (simulating mechanical stresses in the washing machine), and resultant damages were discussed and co-related with washing damages. The bending test was performed by bending the FPCBs at 90° over the circular rod and under the known hanging load.

An integrated electrochromic–hybrid supercapacitor (EHSC) is demonstrated; the device’s operation (charging–discharging) is indicated by optical changes (from colored to transparent). The heart of the device is an electrochromic metallo–organic layer that functions as both the battery‐type electrode and the charge indicator. The capacitive electrode is a layered composite of multiwalled carbon nanotubes (MWCNTs) and a conductive polymer (poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate, PEDOT:PSS). The device operates under low potentials (−0.6 to 2 V), displays high energy and power densities (≈2.2 Wh kg−1 and ≈2529 W kg−1), a high coulomb efficiency (99%), a short charging time (≈2 s), and a charge retention (V½) of ≈60 min. Stability, both in color and energy, for more than 1000 consecutive charging–discharging cycles is demonstrated. No significant changes in device temperature are indicated under the operating conditions. The EHSC is wired with a conventional circuit board to be charged and subsequently to operate a diode. The results demonstrate the potential of metallo–organic assemblies for usage in these types of supercapacitors.
