“…Q-DLTS is the charge relaxation technique based on the measurement of transients produced during discharge time interval followed by required charging potential [48][49][50]. In our case, we have intentionally subjected the PVA electrolyte at ground zero potential and applied 1 V charging bias to the xyplane for a limited duration of * 10 ms. After this duration, the applied bias was removed and the device reduced its potential from 1 V to the ground zero in a time duration known as ''Discharge time.''…”

Poly-vinyl alcohol (PVA)-based electrolytes can play a vital role in the development of supercapacitors by providing a desirable charge separator layer with an added advantage of stretchable nature. These properties enable them as a global contender in wearable electronics and charge storage applications. In this study, the PVA-based electrolyte has been synthesized with potassium hydrooxide (KOH) as ionic migration agent, which may enhance the electronic double-layers capacitance (EDLC) phenomena. In order to mechanically strengthen the graphene-based activated carbon, larger pore fabric is utilized for its encapsulation. Post-fabrication analysis of the supercapacitor using the standard imaging/microscopy techniques (scanning electron microscopy, electron-dispersive electroscope, and atomic force microscopy) are carried out as initial diagnostic test. For detailed electrical, optical, and charge-based evaluation, electrochemical impedance spectroscopy (EIS), Nyquist plot analysis, currentvoltage (I-V) measurements, charged deep-level transient spectroscopy (Q-DLTS), and photoluminescence spectroscopy (PLs) are performed. The fabricated supercapacitor took * 30 min to completely discharge itself at ''full load operation.'' The band diagram, at carrier transport levels, has also revealed the presence of two possible trap centers which may be responsible for the degradation and/or overall stability of the supercapacitor.

“…And the test vector of easy to test faults may detect difficult to test faults, so there is no need to test difficult faults separately. Therefore, the goal of the first stage test is to test the easy faults in the circuit, simulate all faults by using the initial group and the group deduced by each generation of the algorithm, delete the detected faults from the fault table until no faults are detected for several consecutive generations, and enter the second stage to carry out single fault test for the difficult faults [17]. According to the two objectives of test generation, the fitness function of generating test vector is set as follows…”
