I was super curious about the Core Body Temperature Sensor. Running in the desert in the summer can be challenging, and it’s easy to overheat to a dangerous level. As an athlete, we are are constantly seeking the newest and greatest technologies. The more data, the better! A new gadget that has captured the attention of the sports community is the Core Sensor. But what does it do? It monitors your body temperature, which can be ideal when working out in warmer temperatures. Before trying the CORE sensor, I had a few questions:
- How accurate is the Core Body Temperature Sensor? It’s actually fairly accurate.
- Is the Core Body Temperature sensor invasive? No!
About the brand CORE:
The CORE sensor was created by greenTEG AG, a company that emerged from the Swiss Federal Institute of Technology in 2009, which has since been involved in developing various sensors. It was first used at the Tour de France and has since grown in popularity.
I do wish there was more information about the brand.
How Does the Core Body Temperature Sensor Work?
First, you are going to put the Core Sensor onto your body. There are a few ways to do this, including sticky pads or attaching it to a heart rate monitor strap. You would think the Core Sensor just measures the skin temperature, but that isn’t the case. The CORE sensor measures and transmits both skin and core temperatures via ANT+ and Bluetooth Smart technologies. This allows someone to measure their core temperature to a fraction of a degree Fahrenheit.
What makes the Core Body Temperature Sensor different?
- Provides insights into your body temperature. This is essential for athletes and can prevent overheating in races.
- Continuous monitoring
- Size: 50 mm x 40 mm x 8.35 mm, only weighs 12 grams
- Non-invasive (clipped onto the chest)
- Battery Life: 6 days continuous transmission (6 weeks in sleep mode)
- Charge time: 2 hours via USB
- Weight: 12 grams
- Data storage capacity: 84 hours
- Water-resistant (IP67) up to 1.5 meters
- Bluetooth BLE & ANT+ Connectivity
My Experience with the Core Body Temperature Sensor:
Inside the box, there was the actual device, of course, with several sticky pads to attach to the pod. These pads are meant for single-day use. I’ve heard rumors you can use them for more than one workout, but I haven’t. Plus, the USB cable to charge. I still wish all brands went to a USB-C standard charge port. The amount of different cables I have is… a lot.
There are a few different ways to mount the CORE sensor, including the sticky pads and attaching to a heart rate monitor. It seems like most athletes attach to a heart rate monitor strap. You can even purchase a chest or arm strap on the website if that interests you. After deciding how you want to attach your Core Body Temperature Sensor, you pair it with your smartphone.
While it’s currently winter in the Mojave Desert (and yeesh, it’s been colder than usual), I know the Core Body Temperature Sensor will be best used during the summer months. I appreciate that you can see the data right there with no issues. The thing that interests me is it’s fairly hard to validate the accuracy of the Core Sensor. Sure, you could check your temperature with a thermometer, I suppose. But watching the data change, it does match what I theoretically thought my body would do.
What I also found interesting is there are so many different uses for the Core Body Temperature Sensor outside of sports. For those living in extreme temperatures, you might want something to monitor your body temperature, especially if you are working outdoors in extreme elements. Or even in the hospital setting, it seems like there are dozens of practical uses for the Core Body Temperature Sensor.
Cost: $285
At $285, the Core Sensor is not cheap. But there isn’t really anything that does anything similar, so I do think it’s a good investment if you find yourself overheating often or somewhere that it is super hot.
Core Body Temperature Sensor Conclusion:
The Core Body Temperature Sensor stands out as a remarkable innovation in fitness technology. With its roots in scientific research and proven utility in professional sports, the CORE sensor can offer a glimpse into anyone’s body temperature. While the price point of $285 may give pause, the sensor’s unique capabilities, non-invasive design, and comprehensive data tracking present a compelling case for its value. Finally, and lastly, it seems like there is just so much technology for running and sports in general now. Gone are the days when you put on a $100 pair of running shoes and just “go running.”
Who should buy the Core Body Temperature Sensor? If you are an athlete looking for more data on your workouts, or you are working out in extreme conditions.
Who should not buy the Core Body Temperature Sensor? There isn’t a reason you shouldn’t, but a lot of people living in more temperate areas might find it’s not worth it for them. I’ve found it’s awesome for super high or inclement weather. So if you live somewhere hot, you’ll likely appreciate it.
