It uses a Nottingham Trent University with the Prowhite Twist Tester 1009 machine they edited to make a 180º rotary twist. The PDMS-encapsulated copper-polyimide PCF8883US bare die circuit was embedded into the core of a yarn for this experiment. Each e-yarn had a 5g counter-weight attached to one end to keep the e-yarn straight and taut during each twist whilst the other end was attached to the rotary twist arm. The experiment methodology was organised into a factor 10 set intervals of twists of increasing difficulty. This would measure the circuits’ robustness against twisting with time. Hence, the twisting test was divided into 25-twist interval stages of 10, 50, 100, 500 and 1000, and 5000 until the maximum total number of twists was recorded. After each 25-twist interval set, the resistance of the circuit would be measured. The data in this set were collected at Nottingham Trent University at the Advanced Textile Research Group research area.
