"Flexible Organic Transistors and Memory Devices for Eco-Sustainable Electronics".


Flexible electronics has become an enormously explored contender for next-generation low cost electronics due to its applicability in a broad range of applications towards smart textiles and wearable electronics. Moreover, in recent times, devices are being explored for eco-friendly and green electronics, to eventually reduce the impact of increasing E-waste on environment, which has become a severe issue for earth, ecology, and health. Organic transistors receive significant attention as a key device for flexible electronics due to their potential use for multifunctional, circuit, and sensing applications. Along with a suitable substrate, one or many biocompatible or nature inspired material components can be incorporated during the fabrication process to enhance the eco-friendliness of a device. Moreover, various natural proteins such as cellulose, gelatine, chitosan, and albumen can be suitable gate dielectric candidates as a single layer or in combination with organic/inorganic layers. However, multiple processing challenges have to be addressed for demonstrating high performance flexible devices. In this talk, firstly, approaches for designing high performance flexible organic transistors will be discussed. The multifunctional properties of these devices will also be discussed. Many of these devices have shown potential to be used for applications such as real time health monitoring and other circuit, sensing, and memory capabilities. Moreover, many of the engineered dielectrics will also be explored in resistive switching devices for seamless integration of processes for future flexible systems.
