AC Analysis of PEO10LiCF3SO3 Polymeric Material for Memory Storage Application

Mahmoud Z. Iskandarani    

Abstract: Problem statement: Intelligent systems that need to accurately represent human brain requires analogue devices such as a neural switch that processes decision signals and can actually remember the made decision. Polymeric material such as PEO10LiCF3SO3, which previously used in high energy, long life storage batteries, is used here to implement the principle of storage with the required analogue memory. Approach: A number of PEO10LiCF3SO3 devices tested in a controlled environment and their impedance response to both frequency and temperature recorded, analyzed and plotted for interpretation. Results: The tested devices showed ability for charge storage due to its variable impedance response at a range of frequencies, while sustaining very high impedance at DC. The device response found to be affected by intermediate temperatures, with symmetrical response at both low, mid and high temperatures. Conclusion: The designed and tested device showed promising characteristics in terms of memory storage as a neural switch. Its high impedance at DC and low impedance at high frequencies with logarithmic response represented the desired features in a reprogrammable analogue device.
