Planar Integrated Dual-Mode Sensor for Material Differentiation

Abstract: In this proposal seminar, a study on the development of a planar integrated dual‑mode sensor for material proximity detection will be presented. A review of existing literature highlights the limitations of conventional single‑mode sensors: those relying on magnetic field interaction are restricted to conductive targets, while those employing electric field interaction respond to both conductive and dielectric objects but cannot distinguish between them. This gap motivates the design of a shared‑geometry planar sensor structure with dedicated signal conditioning circuitry. By sequentially exciting magnetic and electric field responses, the sensor aims to decouple the two modes of operation, thereby enabling discrimination between conductive and non‑conductive materials. The approach is expected to minimize cross‑sensitivity and avoid strict frequency constraints that limit many current solutions. The seminar will present the literature survey, articulate the identified research gap, and outline the proposed methodology and preliminary design considerations for the sensor system.
