Sleep / Bed sensor platform (BedSense)

2M has buildup over the last decade extensive knowhow and expertise on bed sensor monitoring solutions for a wide variation of applications. 

Sensors for contactless bed monitoring

Most of our experience is in the selection of the right sensor for placement on top, below or fully integrated into the mattress. Sensors that work reliable under all conditions independent of the person or bed characteristics.

Algorithms for reliable feature extraction

The accuracy and robustness of bed sensors is to a large extend made in the quality of the algorithms used. Over the years we have build up a lot of expertise on what works and what not. This enables us to create new solutions, that work reliably, with short development times.

Bed Sensor Monitoring

Application areas

At 2M we mostly focus our bed sensor development efforts on medical, sport and (home) rehabilitation applications in which accuracy, sensitivity and specificity is important. We provide both streaming and event based solutions. These last two parameters are especially important when the bed sensor signals are used to alarm or warn third parties. False alarms should be avoided at all times. The same technologies can also be used for consumer applications.

Starting point for new OEM product developments

BedSensor placed under the mattress

Minimize disturbance for the patient also over long measurement times.

Use in medical and professional home applications

Robust durable and cleanable design.

Physiological signals

In/Out bed detection. Movement / motion. Breathing rate. Heart rate.

Customization 4 new applications

Customization of product design, algorithms / feature extraction, wireless or wired interfacing in other systems.

Extensive experience with bed sensor related algorithm development.

Clinical research network for testing and validation

Over the years we have build up a diverse network of clinical and research partners to quickly verify and validate new applications against professional polysomnography systems.  

2M Bedsensor

Bed sensor Demonstrator for testing new applications

2M can provide the BS100 demonstrator to test and explore new applications. We can deliver one to small series for first investigations, field trials and research studies. This enables quick assessment of our client’s ideas and enables fast creation of proof of concepts, which helps to clarify user requirements and product specifications.

Experienced in bed sensor technology

2M has been active in sleep sensing measurement principles and algorithm development for a number of years. From the various medical research projects we selected the best technologies from a sensing, pricing and production perspective.
 
We have experience with optical microbending, piezo & accelerometer based bed sensor and force sensing resistors (FSR) that depending on the application can work stand alone or in combination if the application requires. 
 
We have build and perfected the required algorithms to turn raw BCG data into useful information and features. 
 
Furthermore we have gained quite some practical experience and can quickly evaluate what will work and what not. We have a number of bed structures and mattresses that we can use for quick testing and prototyping a wide range of applications.

Bed Sensor based on optical microbending

We have gained quite some experience in optical microbending solutions for non-contact measurement of a number of patient parameters.
