摘要

Medication nonadherence, especially unintentional lapses caused by forgetfulness, chaotic lifestyle, cognitive or functional limitations, remains an important driver of disease progression, disability or in severe cases, death. While this problem has been tackled recently with various degrees of success, there is a clear need for solutions that simplify patient interaction with medication and reduce its inherent barriers. This paper presents a proof-of-concept system that dispenses medications at prescribed intervals, senses presence, physically prevents early or excess dosing, verifies dose release with a dual sensing mechanism, and escalates reminders to both the patient and a caregiver. The prototype also integrates a lockout and dual-sensor verification to prevent early or excess dosing, an alert system and secure lock module. The mechanical design, sensing and electronics, and the logic flow are also described, followed by engineering-focused bench protocols and test outcomes. This type of device is designed to be easily replicable using off-the-shelf components while aligning with human-factors and safety constraints for home use.
