“…These notions have expanded the horizons of research and commercial endeavours [ 7 , 8 , 24 , 33 , 34 , 35 ] to produce devices that enable measurement of BP outside the constraints and limitations of the conventional brachial cuff sphygmomanometers to encompass not only wrist-worn devices but other devices with other form factors [ 33 , 36 , 37 ] or those that make use of smartphone technology [ 38 , 39 ]. Applications are also extended to contactless techniques, making use of optical imaging to detect cardiac related pulsations through skin colour change of the face and other locations [ 40 , 41 ]. In most cases, the underlying technology is the use of the peripheral PPG, mainly associated with PTT or PAT measurement.…”

The global health burden presented by hypertension is providing increased motivation for improved means of collection of blood pressure (BP) data. A growing area of research and commercial activity is the use of wearable devices to provide BP data using non-invasive cuffless techniques. The accelerated progress in recent years, particularly relating to connectivity of smartphone technology, has promoted the availability of consumer devices that provide values of BP. The main types of devices are wrist-worn, watch-type devices with sensors that typically record a photoplethysmography (PPG) signal, sometimes also with an electrocardiography (ECG) signal. The general underlying concept of the cuffless BP measurement in most device types is the association of BP and the travel time of the arterial pulse between two locations, determined from the time delay between the ECG and PPG signals. Other methods may involve additional analysis of the PPG waveform features. Experimental data are presented to illustrate the challenges presented by cuffless BP techniques in obtaining reliable BP measurements when the change in BP is caused by different stimuli affecting cardiac and vascular mechanisms. These effects influence the association of the measured and physiological BP change, thus presenting significant challenges and potential limitations in the use of cuffless BP devices for the diagnosis and treatment of hypertension.

The development of non-contact techniques for monitoring human vital signs has significant potential to improve patient care in diverse settings. By facilitating easier and more convenient monitoring, these techniques can prevent serious health issues and improve patient outcomes, especially for those unable or unwilling to travel to traditional healthcare environments. This systematic review examines recent advancements in non-contact vital sign monitoring techniques, evaluating publicly available datasets and signal preprocessing methods. Additionally, we identified potential future research directions in this rapidly evolving field.
