Mattress with Sensors Reports Unauthorized Usage

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll be discussing pressure sensors used in mattresses.

Mattress with Sensors Reports Unauthorized Usage

If Papa and Mama bear had a Durmet Smarttress mattress, they would have received a message on their cell phones regarding the unauthorized usage of their beds. Developed to provide instant feedback regarding motion of the mattress, the system could even report kids jumping on the bed. The mattress employs an array of 24 ultrasonic sensors to detect activity. Algorithms analyze the motion on the mattress and the system sends alerts to the mattress owner’s cell phone.

Arrays of pressure and other sensors have been used for years to monitor activity and the weight distribution of patents to avoid bedsores. Typically, maximum measurements (around 13.2 kPa  or 1.91 PSI) allow a 2 PSI pressure sensor to be used in several isolated air-filled compartments in a mattress to alert a caregiver. More recently, similar measurements combined with control electronics have provided increased comfort by using the measurements to adjust the bed (firmer or softer in various areas) for healthy sleepers. The Smarttress takes an Internet of Things (IoT) approach to sensing, analyzing and communicating data to add a new application.
