Research Projects

Flexible electronics is a promising technology that offers a range of low-cost, environmentally friendly electronic devices that can be bent, rolled, or folded without losing functionality. Organic field-effect transistors (OFETs) are the basic building blocks for various electronic devices, and researchers worldwide are working to achieve superior performance in these devices. The PI's group has demonstrated high-performance flexible OFETs on plastic substrates with high stability under mechanical stress. However, achieving superior performance, performance reliability, and low power consumption is a major concern in standard applications of flexible electronics. The proposed project aims to fabricate operationally stable OFET devices on unconventional substrates like plastic, paper, and cloth, supporting low operating voltage and investigating cost-efficient methods for large-area fabrication. OFETs will be used as the basic building blocks for final circuits and sensors, with optimized graphene electrodes to improve strength and reduce production costs. Processes will be developed to functionalize the surface of biodegradable substrates like paper or cloth, making them suitable for device fabrication. Performance optimization will be done through various combinations of dielectrics, semiconductors, and graphene electrodes, which will be deposited by printing technology. The goal is to develop low-cost sensors and circuits for real-time applications like health monitoring, breath sensing, and temperature sensing. These devices will be incorporated directly on athletes' and patients' clothes, reducing electronic waste and promoting the use of biodegradable substrates.
