Right now, we have seen many skin sensors that monitor human vital signs. If it’s a human, this won’t cause any problems, but what if you need to use it on a hairy animal? Now scientists have developed a sensor that can be used on hairy animals. Developed by a team at Imperial College London, this stethoscope-like device is made of a viscous mixture of silicone and water with a microphone inside.
When applied to the fur of a creature such as a dog through a leash, it will ooze to fill any gaps between itself and the body, eliminating air bubbles. As a result, its microphone makes it easy to get the sound of animal heartbeat and breathing. The audio is converted into a digital signal, which is then transmitted to a nearby portable computer where it is analyzed and displayed in real time.
In addition, the technology can also be used to monitor people’s vital signs through their clothes. In fact, it was successfully tested on five human subjects and could work on up to four layers of fabric. Although it can work with a variety of hairy animals, the device has also been tested on a dog.
Among other things, the device can be used to monitor pets while they are undergoing surgery, without the need to shave hair to place traditional sensors. It can also be used to sniff dogs and track their physiological response to determine when explosives are found.
