Extremely sensitive electrons

European researchers say they have developed an electronic nose with impressive sensitivity that distinguishes the odor from pear and apple.

Experts from the Polytechnic University of Valencia in Spain and Gavle University in Sweden have created electronic nosepieces with 32 sensors that capture the fragrance emanating from the cut fruit.

Spanish researcher Jose Pelegri Sebastia says the study is part of an effort to develop multi-sensor systems that enhance the ability to distinguish complex mixtures of volatile substances. , according to SINC.

The applications of this invention are quite broad, such as in the wine industry, or in the biomedical field.

Several previous studies have shown that it is possible to train dogs to smell cancerous tumors, such as lung cancer, by sniffing a person's breath.

If the electronic nose can detect compounds that the animal smells, the survival rate of the patient will increase due to early detection.
