The present invention relates to a method of producing medium- to thin-film pressure and , humidity sensors by flexographic printing and the sensors themselves. In one aspect there , is a method of producing a sensor for use in a resistance circuit. A flexible substrate is , selected from a material that is bendable that is compressible, or that is , responsive to changes in ambient humidity, while a carbon-resistive ink material is applied to a surface of , the substrate by flexographic printing methods. The sensor can be used in a resistive , detection circuit and includes a resistance detection device and an electric circuit connecting , the device to the sensor. Physical changes …

Why it's free to use
- Filed November 3, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 3, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 3, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
