I think it short-circuited a bit… It’ll probably stop on its own.

Whoever thinks this is broken, raise your hand!

Of course it breaks just when it has a completely new strap, and I ordered three spares just in case… This is so me.

My fitness tracker decided to toss in the towel during vacation so I had to get something new. As I had been enjoying the smartwatch functions I decided to upgrade to a proper watch.

As its main use is to track activities I wanted to check in on its heart rate tracking. Strapped on my chest strap (data collected through Strava) and hit a cardio class.

Long story short I have nothing to complain about. Looks really good.

Commit 26: Noch einmal schlafen, dann ist #39c3! Und danach kommt wieder der Tag der guten Vorsätze. Mehr Sport, weniger Zucker, mehr #opensource. Wie gerne würden wir über Schrittzähler, Cycle-Counter etc. pp. unsere Bewegungs-Bilanz verbessern. Aber #Tracking in der #cloud? #NSA nah? Gruselig.

Aber schaut doch mal beim #OpenTracks Repo vorbei:

:ablobcatheart: Heart Rate Monitoring via WiFi.

Before you decide to click away, thinking we’re talking about some heart rate monitor that connects to a display using WiFi, wait! Pulse-Fi is a system that monitors heart rate using the WiFi signal itself as a measuring device. No sensor, no wires, and it works on people up to ten feet [30 meter] away.

[ImageSource: ucsc.edu] The primary device used was an ESP32, although the more expensive Raspberry Pi performed the same trick using data generated in Brazil. The Pi appeared to work better, but it is also more expensive. However, that implies that different WiFi chipsets probably need unique training, which, I suppose, makes sense. 👾Like you, I’ve got a lot of questions about this one — including how repeatable this is in a real-world environment. But it does make you wonder what we could use WiFi permutations to detect. Or other ubiquitous RF signals like Bluetooth.👾

"WiFi signals can measure heart rate—no wearables needed

Engineers prove their technique is effective even with the lowest-cost WiFi devices

Heart rate is one of the most basic and important indicators of health, providing a snapshot into a person’s physical activity, stress and anxiety, hydration level, and more.

Traditionally, measuring heart rate requires some sort of wearable device, whether that be a smart watch or hospital-grade machinery. But new research from engineers at the University of California, Santa Cruz, shows how the signal from a household WiFi device can be used for this crucial health monitoring with state-of-the-art accuracy—without the need for a wearable.

Their proof of concept work demonstrates that one day, anyone could take advantage of this non-intrusive WiFi-based health monitoring technology in their homes. The team proved their technique works with low-cost WiFi devices, demonstrating its usefulness for low resource settings.

A study demonstrating the technology, which the researchers have coined 'Pulse-Fi,' was published in the proceedings of the 2025 IEEE International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT).

A team of researchers at UC Santa Cruz’s Baskin School of Engineering that included Professor of Computer Science and Engineering Katia Obraczka, Ph.D. student Nayan Bhatia, and high school student and visiting researcher Pranay Kocheta designed a system for accurately measuring heart rate that combines low-cost WiFi devices with a machine learning algorithm.

WiFi devices push out radio frequency waves into physical space around them and toward a receiving device, typically a computer or phone. As the waves pass through objects in space, some of the wave is absorbed into those objects, causing mathematically detectable changes in the wave.

Pulse-Fi uses a WiFi transmitter and receiver, which runs Pulse-Fi’s signal processing and machine learning algorithm. They trained the algorithm to distinguish even the faintest variations in signal caused by a human heart beat by filtering out all other changes to the signal in the environment or caused by activity like movement.

'The signal is very sensitive to the environment, so we have to select the right filters to remove all the unnecessary noise,' Bhatia said.

The team ran experiments with 118 participants and found that after only five seconds of signal processing, they could measure heart rate with clinical-level accuracy. At five seconds of monitoring, they saw only half a beat-per-minute of error, with longer periods of monitoring time increasing the accuracy.

The team found that the Pulse-Fi system worked regardless of the position of the equipment in the room or the person whose heart rate was being measured—no matter if they were sitting, standing, lying down, or walking, the system still performed. For each of the 118 participants, they tested 17 different body positions with accurate results.

These results were found using ultra-low-cost ESP32 chips, which retail between $5 and $10 and Raspberry Pi chips, which cost closer to $30. Results from the Raspberry Pi experiments show even better performance. More expensive WiFi devices like those found in commercial routers would likely further improve the accuracy of their system.

They also found that their system had accurate performance with a person three meters, or nearly 10 feet, away from the hardware. Further testing beyond what is published in the current study shows promising results for longer distances.
