Measuring the heart rate of great apes in captivity is essential for both health management and animal studies. However, existing most methods are either invasive or inaccurate. Now, researchers have investigated the potential of using millimeter-wave radar technology to estimate heart rate from subtle body movements in chimpanzees.
Their efforts will hopefully pave the way to better practices and techniques for monitoring heart rates in wild and captive primates.
Thus, it's no wonder a few techniques have been devised to measure heart rate in great apes. Besides standard contact measurements, the most prevailing one consists of attaching a wireless device to the animal to monitor and transmit its heart rate remotely. However, installing the device often requires anesthesia, which carries risks. Moreover, the device itself might cause stress to the animal or others in its group.
Millimeter-wave radar technology has been extensively developed for applications in automated driving and medicine, but after speaking with a radar researcher at a reception at an academic conference, we felt that it could open up a new field of study if applied to primates other than humans; thus, we began our joint researchTo test their approach, the researchers performed experiments during the annual health checks of two adult chimpanzees at Kumamoto Sanctuary, Wildlife Research Center,...
The researchers hope that the findings of this work pave the way to more innovation in the methods used to monitor vital signs in captive animals, including heart rate and respiration rate." With any luck, these techniques could help us not only keep our closest relatives healthy, but also lead to a better understanding of them. This advancement opens avenues for deeper research into primate behavior and physiology, benefiting captive and wild primates and enhancing our understanding of these creatures and their environment.
