Abstract

In today's modern age, there is a growing need for temperature sensors that can conform to the skin and monitor body temperature continuously. Achieving this requires the miniaturization of the sensor and careful selection of the active layer stacking. Further, it is important to check the effect of the active layer stacking on the sensor performance. In this context, we present the performance evaluation results for a polymer-based flexible temperature sensor designed to conform to the skin. This sensor utilizes PEDOT:PSS + GO composition as the temperature-sensitive material developed on top of a flexible PET substrate. The experimental results demonstrate that the performance of the sensor is dependent on the active layer stacking and electrode separation. An impressive sensor sensitivity of 1.205 %/° was achieved through sensor miniaturization and a single active layer stacking. This shows the performance tuning of a temperature sensor using active layer stacking.
