摘要

This paper proposes a miniature electronic nose (e-nose) for breath analysis. The proposed e-nose is composed of a sensor array, signal processing, and artificial intelligence. The conductive gas sensor is a micro-heating sensing device deposited by nanomaterials. The sensor signal is processed by an AI edge accelerator based on computing-in-memory (CIM) architecture, achieving an advanced system energy efficiency of 18.42 TOPs/W.
