Impulse Radar for Human Detection and Contactless Vital Signs Monitoring

Technology Overview

This technology is based on a single chip implementation of an Impulse Radar system and features the following abilities:

  • See through: Our sensor can be used in the home automation market where it can see through walls, ceilings and doors, enabling everyday products to come to life. This function can also be used in commercial settings to see-through normal building materials, product casings, and even in the art world to look through a painting in a gallery. The sensor can be built into walls or products thereby enabling hidden and tamperproof installations without compromising design or security.


  • Presence: In home and building automation, presence detection is crucial even if a person is sitting still. This technology is able to detect presence from a person’s breathing, even if he is sleeping on the couch or sitting still in his office reading. This increases comfort level because the person does not need to keep moving all the time to keep a light on. This is also a big advantage in security applications. 


  • Motion: Detecting motion is something that this sensor can do very well. Its sensitivity enables it to detect very small movements like the ones from your chest when you breathe, or larger movements such as walking.


  • Adaptive Sensing: Our sensor can combine all its features through adaptive sensing. Our technology can seamlessly switch between features and adjust parameters such as detection range and sensitivity during operation.


Technology Features & Specifications

Operating at sub 10GHz frequencies, the radar system-on-chip can see through obstacles and detect even the smallest movements, its performance being optimised for occupancy sensing and respiration monitoring.

The radar transceiver is able to operate completely autonomously and can be programmed to capture data at predefined intervals and then alert or wake up a host microcontroller or digital signal processor through dedicated interrupt pins. The Power Management Unit controls the on-chip voltage regulators and enables low-power applications to use efficient duty cycling by powering down parts of the circuit when they are not needed. The system can be configured to consume less than 1mW in idle mode when all analog front end components are turned off.

Potential Applications

  • Sleep Monitoring: Non-contact sleep monitoring and sleep stage analysis to help improve sleep quality and well-being


  • Baby Monitoring: Non-contact baby respiration and movement monitoring for parents' extra peace of mind.


  • Light & HVAC Control: Occupancy sensing to help reduce power consumption and increase comfort


  • Safety & Security: Intruder detection, location finding and alarm systems


  • Infant Presence Sensor: Non-contact real time occupancy sensing of infants in cars.


  • Elderly Care Monitoring System: Remote monitoring to track respiration patterns and flag irregularities.

Customer Benefits

Monitoring sleep habits can make us more aware of our sleep health, indicate sleeping disorders that are potentially dangerous, and help us improve our lives in general.

Monitoring vital signs, such as blood pressure, pulse rate and respiration rate, is an important component of patient care and can be done in a medical setting or even at home. Respiration rate is one vital sign that can actually provide insight into one’s general state of health and can also be a valuable indicator of underlying medical conditions.

Using occupancy sensing to automatically turn off task lighting and electrical appliances when they’re not being used by building occupants achieves more though than just conserve power and cut energy bills, it helps to reduce carbon emissions, and prolong the life span of all kinds of equipment.

User experience can be enhanced when such monitoring and sensing are done in an unobtrusive and non-contact way, such as by using this impulse radar technology.
