Researchers at the Indian Institute of Technology (IIT) Delhi have demonstrated a technique using the commercially available polymer 'Cyclic Transparent Optical Polymer (CYTOP),' which could pave the way for advanced electronic devices with built-in data storage and encryption capabilities. This technique can be applied to a variety of materials, offering the potential for a wide range of applications, including renewable energy generation from rainwater and chemical sensing for water quality monitoring.

The study showed that CYTOP can hold the inserted charges for a long duration, which is not generally possible with other materials. This property of CYTOP can be utilized to write the information at the nanoscale in the form of charges, which can further be read by Electrostatic Force Microscopy (EFM) only.

IIT Delhi's Study

A study titled “Determination of surface charge density and charge mapping of CYTOP thin film in air using Electrostatic Force Microscopy," by research scholar Shalini Singh from the School of Interdisciplinary Research (SIRe) under the guidance of Prof. Dhiman Mallick from the Department of Electrical Engineering and Prof. Ankur Goswami from the Department of Materials Science and Engineering at IIT Delhi and in collaboration with Prof. Stefan A. L. Weber from Max Plank Institute of Polymer Research and University of Stuttgart, Germany, was recently published in ACS Langmuir. Research Scholar Shalini Singh said, “This study may give a direction towards the application for ultra-high sensitive sensors and data storage for the memory devices.”

“The present investigation would allow us to write anything on an electret substrate (material that can store charge indefinitely) by using a suitable charge injection mechanism and can only be retrieved under a specialized instrument using a particular protocol. CYTOP has shown significant promises in that front, which can retain charges for more than 100 years.” said Prof. Dhiman Mallick, Department of Electrical Engineering, IIT Delhi.
