The paper presents the fabrication and implementation of non-contact laser-induced graphene (LIG)-based level sensing systems. The LIG has been formed from cork substrates to induce sustainability and biocompatibility of the sensing systems. LIG-based sensors have been highly effective for multimodal applications due to their ease of customisation, rapid fabrication, quick response, and high sensitivity. These LIG-based sensors have been used as non-contact sensors to detect the changes in fluid level. The sensors were embedded in signal-conditioning circuitry for real-time applications. The results presented in this paper provide proof of concept for utilising these prototypes for precise liquid level measurements in industrial applications.
