Title:
DUAL-FUNCTION ACTIVE MATRIX SENSOR ARRAY
Document Type and Number:
WIPO Patent Application WO/2017/110968
Kind Code:
A1
Abstract:
A method is provided for making multiple environmental measurements using a single sensing element. Each sensing element (sensel) includes a thin-film transistor (TFT) and a passive element. Typically, a plurality of sensels is provided arranged into an array. In response to an electrical stimulus, an electrical measurement is supplied that is responsive to a change in TFT electrical characteristic correlated to a first environmental condition, as well as a change in a characteristic of the passive element correlated to a second environmental condition. When the sensels are formed in an array, a plurality of electrical measurements is supplied corresponding plurality of locations on a monitored surface. Some exemplary environmental conditions include temperature, pressure, moisture, chemicals, oxygen, solution pH, salinity, and shear. The method determines the first environmental condition independent of the second environmental condition, while determining the second environmental condition independent of the first environmental condition.
