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.
Murata is a leading manufacturer of electronic components, modules, and devices.
The complete range includes all passive components, sensors, timing devices, filters and modules, and has the widest range in the industry.
Although the company is known as a global manufacturer of components, it is also a world leader in Bluetooth® & WiFi™ modules, standard and custom power modules and devices for healthcare.
