Abstract: The present invention relates to a sensor for determining humidity. A humidity sensor (30) comprises of a substrate (32); a bottom membrane (34) positioned above the substrate (32) and a top membrane (36) positioned above the bottom membrane (34) forming a dielectric layer (38); and a plurality of inter-digitated electrodes (40) with changing capacitance in accordance to change in humidity detected by the dielectric layer (38) embedded to the top membrane (36) wherein a plurality of trenches (42) are embedded to the bottom membrane (34) or to the substrate (32) thereby increasing area of exposure to humidity. The present invention also relates to a method for fabricating a humidity sensor.

Abstract: A novel humidity sensor is described. The capacitive humidity sensor comprises at least two pairs of electrode contact pads (24) spaced apart; and a moisture sensitive film (26) formed around the electrode contact pads. The sensor is characterized in that, at least a pair of metals (28) connect the electrode contact pads to form a pair of 1-shaped electrodes of a capacitor, wherein the capacitance measured changes according to humidity. Another sensor embodiment can be formed with contact pads exposed at two side of the moisture sensitive film. A method of fabricating the sensor is also described.

Abstract: The present invention provides an ISFET sensor device and a method to fabricate the ISFET sensor device with nanostructured membrane which will improve the sensitivity and efficiency of the device. The nanostructures can be in unlimited shape or design, in the form of nanowires, nanorings or nanoparticles, fabricated with the function to increase the sensor sensitivity by increasing the surface area of the membrane exposed to the sample solution or electrolyte. The nanostructured membrane can be formed either by nanofabrication techniques which includes lithographic patterning, pattern transfer, thin film deposition and etching methods or by spin coating of nanomaterials and nanowires using various materials, not limited to, such as, Si3N4 [32], polysilicon [34] and metallic nanowires.
