3D printing simulation nose sensitive sniffing detectable dangerous goods [Full text]

Scientific and technological developments dog has amazing sense of smell, in addition to being used in rescue and search and rescue or criminal check, you can even tell the dog to sniff out whether humans suffering from cancer and other diseases. According to foreign media, the staff of the US National Institute of Standards and Technology recently used 3D printing technology to create a simulation nose, which is even more odor-recognizing than a real dog, except that it is very similar to a dog's nose in appearance. Even stronger.


It is understood that the sensitivity of this simulated nose is 16 times that of a normal dog and can detect gas outside 4cm. Its breathing rate reaches 5 times per second, which makes it possible to more accurately detect gas molecules in the air. In addition to accurately identifying everyday odors, it can also identify dangerous goods. This helps the police to quickly locate dangerous goods and eliminate potential accidents.

In addition, the 3D dog nose can also detect drugs, pathogens, also has a broad application prospects in medical clinics.

Ultrasonic Level Sensor

The ultrasonic level sensor integrates non-contact switch, controller and transmitter into one, suitable for small storage tanks. Ultrasonic liquid level sensor flexible design can be used in the integrated system or a substitute float switch, electrical conductivity and static pressure type sensor, and also suitable for the fluid flow control and chemical feed system of integrated application of ultrasonic liquid level sensor is widely used in all kinds of atmospheric storage tank, tank, small cans and small container, the pump lift stations, waste water storage tank, etc.
