Abstract

Organic electronic devices are fundamental electronic components (diodes, transistors, etc) based on organic semiconductors. They are widely investigated for potential low costs technologies since they can be processed using low temperature and scalable processing techniques such as printing. While some organic electronic devices, such as organic light emitting diodes have reached the commercial market as technologies for screens and lighting, organic electronic devices for biosensors and bioelectronics are rapidly developing. This includes the development of organic neural interfacing devices for recording brain activity, the delivery of neurotransmitters for therapeutic purposes, real-time stimulation of neural cells, neural synaptic devices, artificial retinas, neuromorphic devices, DNA sensors, glucose sensors, cortisol sensors, and lactate sensors. The applicability of organic devices to such a vast and diverse array of applications owes partly to their ability to be flexible and conformable, due to the inherent flexibility of organic semiconductors. Additionally, organic semiconductors can be directly deposited into complex patterns using techniques such as inkjet printing.
