About Us

Sensifree is a medical device company, on a mission to revolutionize how patients are cared for in hospitals. We develop continuous, noninvasive hemodynamic monitoring solutions, based on our proprietary NEST™ (Noninvasive Electromagnetic Sensing Technology) platform. Our first product provides continuous blood pressure monitoring for patients admitted in the ICU, undergoing surgery or recovering from procedures. This product offers beat-to-beat reading and waveform display as the invasive arterial line, without the risks and costs associated with it.


NEST™ Platform

Our proprietary NEST™ (Noninvasive Electromagnetic Sensing Technology) platform is a novel, patent pending, RF based technology for continuous, noninvasive hemodynamic monitoring. Our sensor produces a unique signal from the radial artery, tracking the distention of the pulsating blood vessel, thus generating a continuous waveform that tracks the arterial pressure wave. We then use our proprietary algorithms, based on biomechanical modelling of the cardiovascular system to extract and track systolic and diastolic blood pressures, as well as mean arterial pressure (MAP). Stroke volume and cardiac output will be added in the future.

Key benefits of the NEST™ platform:

  • Noninvasive application
  • Continuous waveform trace display
  • Near real time blood pressure values calculation
  • Early detection and alert of condition deterioration
  • Based on analytic cardiovascular model. No need for human parameters database that is inaccurate

With every beat of the heart a pressure wave is created, traveling down the arteries. The blood pressure inside the arteries is constantly changing between its systolic and diastolic values. This periodic increase and decrease in blood pressure creates a distention in the artery wall.

Sensifree has developed and miniaturized RF based technology that senses artery distention for measuring blood pressure.



Hemodynamic Patient Monitoring

Achieving hemodynamic stability is crucial in improving patients’ clinical condition. Several hemodynamic parameters such as heart rate, blood pressure and cardiac output are important to monitor and control. Abnormalities of any of these parameters may indicate hemodynamic instability which may lead to inadequate perfusion to support normal organ function. Two of the variables that most directly reflect organ perfusion are blood pressure and cardiac output [1]. Sensifree’s proprietary NEST™ platform will enable noninvasive and continuous measurement of blood pressure, heart rate, stroke volume and cardiac output parameters in patients who need monitoring in various care settings, such as –

  • Operating rooms
  • Intensive care units
  • Emergency departments
  • Post-surgery recovery units

Hospital Blood Pressure Monitoring Redefined

In many situations, close monitoring by arterial line is desired however not viable, due to various reasons, such as risk / benefit profile or contraindication. Our first product meets that need by offering a noninvasive & continuous blood pressure monitoring device, enabling arterial line grade monitoring for extended patient populations. The device is virtually risk-free, and requires a simple set up by an nurse or technician. Product consists of a disposable patch, sensor pod and a dedicated bedside monitor.



Sensifree Reports Statistically Significant Concordance of Arterial Pressure Signal Waveform Between its Continuous Non-invasive Blood Pressure Monitoring Technology and Invasive Arterial Line

CUPERTINO, Calif.–(BUSINESS WIRE)–Sensifree, a medical device company developing advanced RF-based hemodynamic monitoring solutions, announces results of a clinical study showing excellent concordance between the signal morphology of its RF based sensor and invasive arterial line, the standard of care for continuous blood pressure monitoring. Clinical data from the study further validate blood pressure extraction and tracking algorithms. Preliminary results demonstrate accurate tracking of systolic and diastolic pressure values.
