The proliferation of diabetes mellitus globally necessitates advanced solutions for insulin storage and transportation to ensure efficacy and user convenience. This paper presents the design and development of a portable insulin case featuring an integrated electric circuit and temperature monitoring system. The innovative device aims to maintain optimal insulin storage conditions, particularly within the temperature range of 2°C to 8°C, essential for preserving the bioactivity of insulin. The core component of the case is an embedded electric circuit responsible for both temperature regulation and real-time monitoring. The circuit includes a microcontroller unit (MCU) interfaced with temperature sensors (thermistors or digital temperature sensors like the DS18B20) that provide continuous feedback on the internal temperature. A pulse-width modulation (PWM) controlled thermoelectric cooler (TEC) is employed to modulate the temperature, leveraging the Peltier effect for efficient thermal management. The integration of a lithium-polymer battery ensures portability, while a power management system optimizes energy consumption, thereby extending battery life. To enhance usability, the case features a digital display panel for real-time temperature readouts, and an alert system that signals deviations from the predefined temperature range via auditory and visual indicators. Data logging capabilities are incorporated, allowing users to track temperature history and verify storage conditions over time. This is facilitated by non-volatile memory modules interfaced with the MCU, ensuring data retention even when the device is powered off. The physical design of the case emphasizes durability and portability. The exterior is constructed from impact-resistant, lightweight materials, ensuring the device can withstand daily use and transport. Additionally, the interior is lined with thermally insulative materials to minimize external temperature influences and enhance the efficiency of the TEC. User safety and ease of use are prioritized through the inclusion of a user-friendly interface, designed with intuitive controls and feedback mechanisms. The device is programmed to provide diagnostic alerts, prompting maintenance actions such as battery charging or sensor recalibration.
