We’ve seen a lot of skin sensors used to monitor human vital signs. If it’s human, it won’t cause any problems, but what if it’s needed to be used on hairy animals? Now scientists have developed a sensor that can be used in hairy animals. Developed by a team at Imperial College London, the stethoscope-like device is made of a sticky mixture of silicone and water, with a microphone inside it.
When it is applied to the fur of a creature such as a dog through a belt, it oozes to fill any void between itself and the body, eliminating the bubbles. As a result, its microphone easily gets the animal’s heartbeat and breathing sounds. Audio is converted to a digital signal, then transmitted to a nearby laptop for real-time analysis and display.
In addition, the technology can also be used to monitor people’s vital signs through people’s 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 on a variety of furry animals, the device has also been tested on a dog.
Among other things, the device can be used to monitor pets during surgery without having to shave to place traditional sensors. It can also be used to sniffer dogs and track their physiological responses to determine when explosives are found.
The study was described in a recent paper published in the journal Advanced Functional Materials.
