Is the heart rate sensor on your smartwatch accurate? Research has shown skin tone may affect whether it is, and companies have responded to the challenge.

There are two common methods to monitor a heart rate in a wearable device, but it is important to understand the limitations of each, says Mark Patrick.

Users could simply press a finger against the sensor and get a heart reading in seconds. The Pixel phones don't have a PPG, but Google's solution is not all that different.

It seems like within the last ten years, every other gadget to be released has some sort of heart rate monitoring capability. Most modern smartwatches can report your BPMs, and we’ve even see… ...

By minimizing the mounting area of the PPG sensor head, it is possible to mount it in a narrow space, which was difficult to install in the past. Expansion of applications through multiple ...

The EmotiBit packs a PPG, or photoplethysmogram sensor, otherwise known as a pulse oximeter, which uses optical methods to detect changes in blood volume beneath the skin.

A tiny sensor that is not much bigger than a grain of rice can detect magnetic fields as weak as those produced by a mouse’s heart. The sensor, known as an atomic magnetometer, could be used for ...

Aria Gen 2 has a PPG sensor for measuring heart rate and a contact microphone to distinguish the wearer’s voice from that of bystanders.

By minimizing the mounting area of the PPG sensor head, it is possible to mount it in a narrow space, which was difficult to install in the past. Expansion of applications through multiple ...
