Our Textile Temperature Sensor is a fabric able to sense temperature. It solves the problem to have a skin compatible temperature sensor for wearable applications, where hard sensors are not comformable to the human body and difficult to integrate in clothing. It also solves the problem to have temperature monitored in extremely thin spaces or in soft objects.
The fact that our fabric is the sensing element of the sensor allows an easy and comfortable integration in every garment or other soft object like a vehicle seat, mattress, sofa, without limiting any aspect of comfort. Also, this sensor can be produced in large sizes and it's perfect to measure the average temperature of a large surface. Fox example it can be used to measure the average temperature of the air flowing through an HVAC duct.
Our idea is novel because it allows to produce sensors made of fabric that are very sensitive to temperature variations than the current state of the art. We have filed a patent, and 5 claims out of 7 have been accepted, thus recognizing the novelty of our solution.
We are currently customizing our sensor to be integrated in newborn baby suits to check body temperature just few seconds after the baby is born. Another application is the integration in a sock to monitor diabetes foot status. In diabetes foot temperature is a critical factor that needs to be constantly measured.
Many other uses are in the industrial field, where temperature is one of the most critical physical quantity being kept under control. Our sensor can also be applied in matresses, sofas or vehicle seats to detect temperature between our body and the back rest or seat, and consequently adjust A/C level and improve comfort.
The market potential is high. Forecasts say that the use of smart fabrics is constantly growing, with two billion dollars in sales projected for the year 2018 and an always growing CAGR (source: Statista, 2015).
This is how our design works: we integrate an extremely fine wire of metal inside a fabric. Working principle is called RTD (Resistance Temperature Device). Changes in electrical resistance measured between both wire ends are proportional to variations of temperature.
Our design is produced by a special textile machine able to work with metal fine wires. It is entirely produced using textile technologies with a very low manufacturing cost, and it can be produced in large volumes with a small percentage of labor cost.
