Wearable sensors to continuously measure blood pressure and derived cardiovascular variables have the potential to revolutionize patient monitoring. Current wearable methods analyzing time components (e.g., pulse transit time) still lack clinical accuracy, whereas existing technologies for direct blood pressure measurement are too bulky. Here we present an innovative art of continuous noninvasive hemodynamic monitoring (CNAP2GO). It directly measures blood pressure by using a volume control… Expand
Control Method for Continuous Non-Invasive Arterial Pressure Monitoring using the Non-Pulsatile Component of the PPG Signal
We propose a new technique enabling continuous control of transmural pressure using the non-pulsatile (DC) component in the PPG signal as feedback. Photoplethysmograph (PPG) contact pressure has aExpand

Wearable hemodynamic sensor
TLDR
It is possible to obtain an absolute value at an early stage, the conversion function, a BP signal obtained by the finger or the wrist can be converted to true BP value at the level of the heart that corresponds to the brachial artery. Expand
Smartphone-based blood pressure monitoring via the oscillometric finger-pressing method
TLDR
A smartphone-based device for cuff-less and calibration-free monitoring of systolic and diastolic blood pressure is comparable to cuff-based devices and extended the oscillometric principle, which is used by most automatic cuff devices, to develop a cuff-without BP monitoring device using a smartphone.

The first study comparing a wearable watch‐type blood pressure monitor with a conventional ambulatory blood pressure monitor on in‐office and out‐of‐office settings
TLDR
The authors have conducted the first comparison study of BPs measured by a recently developed wrist‐worn watch‐type oscillometric BP monitoring (WBPM) device, the “HeartGuide,” and found the difference between the WBPM and ABPM device was acceptable both in and out of the office. Expand

CNAP – Evolution of Continuous Non-Invasive Arterial Blood Pressure Monitoring
TLDR
CNAP concentrates on the clinically important BPinformation such as absolute BP and BP-changes as well as physiological BP-rhythms andBP-waveforms, where other hemodynamic parameters like cardiac output (CO) and dynamic fluid management parameters (e.g. pulse pressure variation PPV) can be derived.
