The determination of moisture and temperature in thin textile-like layers is interesting for a wide range of applications. Especially for body-worn applications, the so-called wearables, a measurement method with the
following characteristics is needed:

• resistant to fluctuations in salinity
• insensitive to stray electric fields or other interferences
• detection area can be easily limited in space
• simple application
• low energy consumption
• Wireless signal transfer such as Bluetooth or Near Field Communication (NFC)
• Low-cost manufacturing possibility

The patented THMS measuring method (for Transient Heat Moisture Sensing) is based on a thermal process and meets all the criteria mentioned.
