| − | The increasing number of deaths caused by cardiovascular disease (CVD) is a global issue. There are several techniques and exams that are used to detect CVDs. One tool that is widely used to monitor heart activity inside and outside hospitals is the pulse oximeter, which is also called photoplethysmograph (PPG). The PPG is an optical technique that collects the heart activity, such as heartbeats and arterial oxygen saturation level in the blood. However, the sensor used in the PPG has some issues regarding the patient's skin tone and movements during the examination. In order to reduce that, we developed a device capable of increasing the local skin surface temperature, provoking vasodilation at the sensor location and consequently, increasing the peak-to-peak (P2P) value of the signal from the PPG.

The PPG is an optical technique that collects the heart activity, such as heartbeats and arterial oxygen saturation level in the blood. However, the sensor used in the PPG has some issues regarding the patient's skin tone and movements during the examination. In order to reduce that, we developed a device capable of increasing the local skin surface temperature, provoking vasodilation at the sensor location and consequently, increasing the peak-to-peak (P2P) value of the signal from the PPG. From a study ran in 13 participants, we obtained an average of 346% of P2P improvement, considering all skin tones and different body composition.
