For high concentration, we are developing QCM type transducers; and for lower concentration, MEMS semiconductor type and FBAR type transducers.

Advantages & Features

Compact and Multifunctional for a Wide Range of Applications

Various smells can be identified by mounting a sensor that can respond to a variety of different smell molecules.
The miniaturized sensor module can be used for a variety of applications, from fixed sensors to mobile applications.

Anomaly detection: Reports abnormalities even in unmanned environments, Inspection robots: Finds problem areas by smell Quality control: Visualizes freshness and spoilage, Exhaled air (pre-disease detection): Manages physical condition by smell, Visualization of smells: How people perceive smells visualize

Smell Identification by Machine Learning

Similarly for human smell identification, the system learns in advance what a certain smell is.
The system remembers the learned results to identify and recognize the smell from memory when it senses the smell.
In machine learning, we have developed an algorithm with good identification accuracy to visualize smells.

Measurement system (reproducibility of measurements): Development of measurement methods with good reproducibility / Machine learning (odor identification): Development of algorithms with good identification accuracy / Transducer (sensor sensitivity): High sensitivity sensor module development / Sensitive membrane (odor selection system): Development of a sensitive membrane that can detect various odors

Smell Sensor System Structure

This system is composed of a sensing unit and an edge terminal-based sensor control unit.
The sensor control unit controls the sensing unit, collects measurements, and performs machine learning.
It supports optional functions to operate in synchronization with environmental sensors, and so is capable of sensing simultaneously with temperature / humidity sensors, CO₂ sensors, and dust sensors.
