Abstract
A syringe system with NFC technology to detect and report state changes is described. The syringe system includes a plunger with sections of different materials, a barrel, and an inlay containing an NFC antenna and a microcontroller. The microcontroller measures capacitance changes between probes on the barrel, indicating plunger movement and position. The syringe system communicates real-time injection status to external devices, ensuring accurate medication administration. The flexible inlay can be over-molded or adhered to the syringe, adapting to various devices, including auto-injectors and manual self-injection systems. The technology supports real-time monitoring and accurate drug dosing.
