Paper-based organic electronics

With the current advances in semiconductor physics, material science, and material engineering, some developments have been reported in the performance and fabrication of cheap light weight electronic components. These electronic components include those made from organic material driven electronic devices such as organic thin film transistors, organic diodes, etc. all having a wide range of applications in various fields including science, technology, engineering, and entertainment. Large area organic thin film transistors can be fabricated on various substrates such as glasses, flexible and rigid plastics, thin-films, etc. to suit different design applications. This thesis work describes the fabrication of organic thin film transistors on biodegradable light-weight flexible paper substrates, and some basic electronic circuitries made from this environmental friendly paper based transistors. This work also highlights possible future work that can be carried out for achieving better performance in some of the circuit applications reported in this thesis. Current research in the performances and characteristics of the environmental friendly transistors has shown that it possesses strong potential for direct applications in biosensors, food technology, histology, biophysics, electrotherapy, computing and electronics. With the light weight paper technology, these devices can be engineered at a low cost into any form and shape to suit design and thus have strong commercial potential that can drive future electronics
