Özet

sensitivity and durability of sensors for optical-photonic applications. Advances inscience and technology have led to the development of low-cost, next-generationsensors on flexible substrates for electronic applications in various fields. Thus, withthe advancement of flexible electronics, flexible sensors for wearable technologicalapplications aimed at real-time monitoring of physiological parameters haveincreasingly become the focus of research. Recently, wearable temperature sensorswith favorable detection performance such as high sensitivity and fast response havebeen widely reported [1-2]. To achieve better temperature measurement performance,new materials such as graphene, carbon nanotubes, and metal nanowires are beingused as temperature sensing materials [3]. Among these materials, carbon nanotubesare commonly preferred in temperature sensors due to their superior electrical,mechanical and thermal properties. In this study, carbon flexible temperature sensorswere developed in wearable technology. As a first step, Ag interdigital electrodes wereprinted on Kapton substrate using silver ink by the aerosol jet printing technique.Subsequently, a carbon nanotube sensing element was developed between the Aginterdigitated electrodes using carbon ink, again employing the aerosol jet printingtechnique. The thickness of the carbon nanotube sensing element was measured as3.16 μm, the average line width was 56.5 μm and the resistance was 1W. Changes inthe resistance values of the developed sensor have been periodically observed.
