Generallyadays, the sensor is too hard and is not suitable for long-term wear. This is also an important reason that restricts the development of smart sensors. When it comes to sensors, everyone can't relate to chewing gum. After all, the sticky gum sticks to the place where it is uncomfortable. Next, I want to tell you that chewing gum is used as a sensor. Is it incredible?

The ordinary chewing gum can be turned into a medical sensor that is sensitive to the shape of the object by simple processing. This is not the plot of a Hollywood blockbuster, but the result of a new medical device research. According to foreign media reports, researchers at the University of Manitoba in Canada are currently investigating the movement of carbon nanotubes into chewed chewing gum to create a movement that captures more subtle and flexible body movements. Sensing equipment.

What is the use of "chewing gum sensor"?

The ordinary chewing gum is first soaked in purified water and ethanol overnight and then dried. They then drip the aqueous solution of the multi-walled carbon nanotubes into the treated chewing gum, and then repeatedly stretched and folded the chewing gum in one direction. After such treatment, the carbon nanotubes are uniformly distributed in the chewing gum and aligned in the direction of stretching. When the shape is changed by an external force, the resistance of the chewing gum changes significantly. The sensor is connected to a conventional monitoring device to measure parameters of human motion such as heartbeat or breathing. They will be used to monitor the subtle movements of the body, including the ups and downs of the chest during breathing, or the fine flow of blood through the body as the heart pumps. The researchers frequently bent their fingers and turned their heads and necks during the test. The results showed that the "chewing gum sensor" maintained high sensitivity even when its length was extended more than five times.

What is the value of “chewing gum sensor”?

Compared to traditional metal sensors or later plastic sensors, the "chewing gum sensor" can be used with the monitored person without losing its effectiveness. Not only that, but the unique flexibility and durability of the chewing gum sensor make it unique in the field of wearable monitoring equipment.

The researchers also found that chewing gum sensors can record small changes in humidity, such as the humidity of a person breathing normally. In the future, the measurement of the humidity of the chewing gum sensor will enable the doctor to monitor the patient's breathing more effectively.

Conclusion: Chewing gum medical sensors may fail if they are subjected to incorrect stretching, bending or twisting. Therefore, the author believes that chewing gum is not necessarily the most suitable material for this new type of sensor.

Long Range LiDAR Radar

Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v.
