Temperature is the most frequently measured parameter in the world. The printed temperature sensor from Witte consists of three additive screen-printed layers: A sensitive material, an electrode, and a protective layer. For the former, Witte uses a PTC (Positive Temperature Coefficient). The latter printed enclosing layer protects against corrosion and moisture. The dynamic data of the temperature sensor, which is printed on PET, TPU or Kapton substrates, can be transmitted digitally via Bluetooth or NFC using FPC or crimp connectors.
Printed temperature sensors are particularly promising tools in the healthcare sector, for example, when it comes to tracking the wound healing process under a bandage. In the clothing industry, too, temperature recordings close to the body with printed sensors are in vogue, as their flexibility allows them to be incorporated into textiles – “wearables” being the keyword here.
Temperature sensors in batteries have a central function. To ensure that these remain durable and function at optimum performance, their temperature must not exceed or fall below a certain range. Temperature sensors are thus important components for a battery management system.
The fields of application for printed temperature sensors are broad and naturally go beyond these three examples. For instance, we are also working on uses in the automotive and logistics industries. Do you have any questions? We look forward to working with you on finding the right temperature sensor for your needs and producing it on our modern printing equipment.
