Area of Science:

  • Biomedical Engineering
  • Logistics and Supply Chain Management
  • Sensor Technology

Background:

  • The COVID-19 pandemic highlighted the critical need for vaccine temperature control during storage and transportation.
  • Maintaining vaccines within the recommended 2°C to 8°C range is essential to prevent loss of potency.
  • Existing solutions may lack comprehensive monitoring or be cost-prohibitive for widespread adoption.

Purpose of the Study:

  • To develop an integrated, compact, power-efficient, and low-cost data logging solution for vaccine transport.
  • To ensure vaccine potency through real-time monitoring of temperature and movement (jerks).
  • To provide a reliable system meeting health organization standards for end-to-end storage and monitoring.

Main Methods:

  • Development of a novel hardware platform integrating sensors, memory, and processing units for the THERMOD (TemperatuRE, Humidity, and MOvement Data-logger).
  • Implementation of interactive algorithms for real-time logging of temperature and 3-dimensional movement data.
  • Data retrieval via direct connection to a host computer/laptop for analysis.

Main Results:

  • The THERMOD device successfully logs real-time temperature and jerk data, enabling detailed monitoring of the cold chain.
  • Cost analysis demonstrates significant cost-efficiency compared to existing solutions.
  • Real-time power performance graphs show THERMOD outperforming current market offerings.

Conclusions:

  • The developed THERMOD data logger offers a robust, cost-effective, and power-efficient solution for monitoring vaccine transport conditions.
  • The system adheres to World Health Organization (WHO) standards, ensuring reliability and compliance.
  • THERMOD provides essential data for assuring vaccine potency and integrity throughout the supply chain.
