Abstract
Integration of sensor modules in contemporary smart devices is imperative for initiating automation in the devices. Among such sensors temperature sensors based on conventional inorganic semiconductors are most common. Temperature sensors are generally used in various electronic devices like smart watches, digital thermometers, digital weather stations etc. Integration of inorganic temperature sensor modules in such organic smart devices adds to circuit complexity, inconsistency, increment in fabrication cost and size of the device. In this research article a new flexible organic thin film temperature sensor is proposed that is inspired from the operational functionality of organic thin film transistors. The proposed organic thin film temperature sensor (OTS) is structurally and behaviourally similar to an organic thin film transistor (OTFT). A comparative analysis of OTS with single gate and dual gate OTFT structures using modelling and simulation is performed to validate its functionality and determine its operational efficiency across different performance parameters. The OTS is found to generate 167% and 17% more drain current then single gate and double gate (DG) OTFTs respectively with same material composition, and voltage regime. Also, OTS has 31% higher temperature sensitivity compared to double gate OTFTs. It will eliminate the need of additional circuit components required to make contemporary inorganic temperature sensors functional with smart organic electronic devices. Hence the proposed OTS being dimensionally and functionally equivalent to a single OTFT could replace the conventional inorganic semiconductor-based temperature sensors to achieve fabrication compatibility and size optimization in modern organic electronic devices.
