Contactless Bed Sensor

The products are component parts of equipment

  • Opens new possibilities in patient monitoring and elderly care in hospitals, assisted living and even at homes
  • Embedded heart and respiration rate and beat-to-beat time signal processing enabling patient monitoring from bed occupancy to condition quality analysis

The BCG technology is available in 2 different formats/products:

SCA11H node 

  • A complete BCG-based sensing component that comprises the sensor, microcontroller and a Wi-Fi transceiver
  • Targeted for software solution- and service providers and OEM system integrators

SCA10H module 

  • Solderable PCB module component comprising the sensor and microcontroller
  • Ideal for equipment manufacturers


The new bed sensor technology is based on the Ballistocardiographic (BCG) principle. When the heart pumps blood there is a recoil effect to the opposite direction. This means that when e.g. lying on a bed, the entire bed will be subject to micro movements due to the blood flow. We use an ultra-sensitive Murata accelerometer to capture this signal. A microcontroller with a specially made algorithms are able to extract heart rate and many other vital signs from the signal.  

The BCG module/node outputs vital signs and bed occupancy information such as:

  • Heart rate
  • Respiration rate
  • Heart rate variability (correlates to stress level)
  • Relative stroke volume (how much blood the heart pumps)
  • Bed status indicator (is the bed empty, is patient in bed, is patient moving in bed)
  • Other information such as a data log of timestamp, signal strength etc.
