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.
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.
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.
