# Oxitone

The main advantage of the Oxitone sensing platform is that it works without the need for an irritating fingertip sensor or chest strap: all sensors are embedded into a conventional watch-like enclosure. What makes Oxitone different?

It is relatively easy to calculate pulse oximetry parameters from the signals taken at the fingertip or one’s forehead where these signals are clean due to a high blood perfusion. However, it is a very complex task to perform when biosensors are placed at one’s wrist. Moreover, it becomes even more complicated when the person performs any physical activities since motion artifacts distort the weak pulse signal so that the blood pulsation can hardly be seen.
