Latest Patents
One of his latest patents is for a polymer-based humidity sensing element. This invention features a porous poly(2-acryl-amido-2-methyl-propane sulphonic acid)-based humidity sensing element that provides an improved range of humidity measurement and response time with minimal hysteresis. The design includes a non-conductive substrate with a pair of electrodes and a porous film formed on these electrodes. The film is created by initially forming a non-porous layer and then subjecting it to heat treatment to develop a porous structure. Additionally, the poly(2-acryl-amido-2-methyl-propane sulphonic acid) can be modified by incorporating various cations to enhance its properties.
Another significant patent involves a solid-state humidity sensor. This method includes dissolving a tungstate salt in an aqueous solution, adjusting the pH, and forming electrodes on an insulating substrate. The substrate is then heated in the solution to create a pyrochlore-type crystalline tungsten trioxide film over the electrodes. This innovative approach allows for the development of effective humidity sensing elements.
