Our artificial olfactory system combines sensing and processing efficiently, mirroring the biological olfactory system's function for energy and space savings.

Revolutionary Artificial Nose Offers Precision Food Spoilage Detection
Scientists have created a chip for energy-efficient computing that incorporates odor-sensing components. This chip has the capability to continuously monitor and report real-time conditions during the entire food spoilage progression, allowing it to detect spoilage. The system is described in a study published in Advanced Science. (1 Trusted Source

Other electronic noses, or artificial olfactory systems (AOSs), have been developed in the past, but they have numerous limitations, including high energy consumption, time delays, and data loss.

Efficient Food Spoilage Detection with Integrated AOS Technology

The AOS developed in this study requires little energy and integrates sensing and computing units on the same chip. It detects food spoilage by employing thin zinc oxide films that sense even very low levels of hydrogen sulfide and ammonia gases, which are high-protein food spoilage markers.

When investigators tested it during the spoilage process of chicken tenderloin, the system continuously tracked freshness scores and food conditions over time. The platform could be used for various applications by adjusting the gas-sensing materials and other parameters.
