About Us

Wearable devices are becoming an everyday companion. At Sensifree, we are pioneering the landscape of contactless sensors for wearables. We work closely with manufacturers of wearables and understand real-life challenges of new wearable devices.
Our mission is to provide sensors that will make wearables comfortable, accurate and consume low power. Our sensor technology is unique and we are making it affordable for the consumer market. Our heart rate sensor is already available and we are currently developing a revolutionary, cuff-less blood pressure sensor.

The Vision

Sensifree has developed a unique, patent-pending sensor technology that solves the shortcomings of optical sensors. Our RF based sensor technology can accurately monitor heart rate from different points on the human body. Unlike current LED optical technology, Sensifree sensors are very low power, deliver robust operation, and give designers and manufacturers the ability to create new wearable products that do not compromise comfort, appearance or usability.

Sensifree partners with wearable manufacturers, fashion brands and luxury watch makers seeking next generation biometric sensors for consumer electronics devices, fitness trackers, traditional watches and smart clothing products.

About Us

Sensifree develops the future of blood pressure monitoring devices, replacing 19th century technology and methods. We provide cuff-free, comfortable, and discrete continuous monitoring of this critical vital sign. We use our proprietary, RF based technology to generate a unique signal from the radial artery and evaluate systolic and diastolic pressures from it.
We aim at revolutionizing the diagnosis and management of hypertension by bringing a new standard of care to clinics, home healthcare and hospitals.
Our first target is hypertension diagnosis and remote patient monitoring, then expanding into consumer healthcare and bedside patient monitoring.


Sensifree developed a breakthrough solution for cuff-free blood pressure monitoring. It is based on our proprietary patent pending RF technology. Our wrist worn device generates a unique signal originated at the radial artery, accurately tracking the dimensions of the pulsating blood vessel, thus generating a continuous arterial pressure wave signal. We then use proprietary algorithm to evaluate and track systolic and diastolic blood pressure values. Our revolutionary approach is substantially different from other proposed solutions, as our sensor generates a signal originated at the artery, which is directly related to the blood pressure inside it. We use a proprietary algorithm, based on modeling of the cardiovascular system, to calculate both systolic and diastolic pressure values.
Our solution comprises of a connected monitoring wearable device, and a cloud processing and storage backend system. The system automatically generates measurement reports with actionable data. In the future, contextualized, cloud based data will be used to identify trends and patterns for early identification and alerts of medical conditions.
We recently entered into research partnership with the prestigious Swiss research organization CSEM. This partnership augments our R&D capabilities and validates our scientific approach.

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.



High Blood Pressure Diagnosis and Management

Hypertension (High Blood Pressure) is the largest epidemic known to mankind. More than 1B people globally are living with high blood pressure[1]. It is a major risk factor for various cardiovascular diseases and stroke – leading causes of death in the US and in most developed countries. Since high blood pressure has no symptoms, less than half of adults with high BP in the US have the condition under control or even diagnosed[2].

Because a single blood pressure measurement taken at a doctor’s office is meaningless for the purpose of diagnosis, high blood pressure is diagnosed today mostly based on data measured at home, using patient-owned devices. This methodology is often inaccurate and missing important information: over diagnosis due to anxiety, under diagnosis due to masked hypertension, and does not provide monitoring of nocturnal (night time) BP, which is important in the overall assessment of patient’s condition.

It is widely accepted that the best method to diagnose high blood pressure and assess effectiveness of treatment is by a 24 hour continuous blood pressure monitoring session. It is the gold standard in the US, Europe, Canada and Japan[3][4][5][6].

Blood Pressure Monitoring Redefined

Our first product is a revolutionary blood pressure monitor, aiming at setting a new standard of care for hypertension diagnostics and serve as a remote patient monitoring guardian.
Based on our proprietary RF technology and advanced algorithms, it offers a compelling value proposition for both patients and clinicians –
• Ease of use – cuff-free, comfortable, lightweight, wireless connectivity.
• Automatic blood pressure monitoring – uninterrupted daily activities, sleep time monitoring.
• Tracking, storing and reporting – producing actionable reports, trend analysis, alerts to improve medication adherence.
