Gas sensors are increasingly being utilized in food spoilage detection due to their high sensitivity, miniaturization, and low power consumption. These sensors play a crucial role in monitoring food quality by detecting spoilage-related gases such as ammonia (NH3), hydrogen sulfide (H2S), and volatile organic compounds (VOCs). Various studies have explored the application of microsensors in this domain, and ongoing research continues to improve their efficiency. This paper presents a comprehensive review of the state-of-the-art MEMS gas sensors specifically designed for food spoilage detection. A comparative analysis is conducted based on sensor design, working principles, sensitivity, operating temperature, and sensing materials. Additionally, the advantages and limitations of different gas sensors are discussed to provide insights into their suitability for food freshness monitoring. Recent advancements in MEMS-based food spoilage detection sensors are highlighted, with a detailed tabulation of their key characteristics and performance metrics.
