Title: Innovations of Shyam P Maheswari

Introduction

Shyam P Maheswari is an accomplished inventor based in Rochester Hills, MN (US). He has made significant contributions to the field of electrochromic devices, holding a total of 2 patents. His work focuses on developing advanced materials and methods that enhance the functionality of electrochromic cells.

Latest Patents

One of his latest patents is for an electrochromic device with an oxymethylene-polyoxyethylene electrolyte. This innovative electrochromic cell features a Li.sup.+ doped oxymethylene-polyoxyethylene solid polymer electrolyte. The design includes a film of ionically doped oxymethylene-polyoxyethylene sandwiched between two complementary electrochromic layers, one of which is tungsten oxide. The other layer can be made from polyaniline or a Prussian Blue material. This configuration allows the electrochromic cell to change color and bleach through the application of an appropriate electrical potential. The electrolyte is stable at elevated temperatures up to about 100 degrees Celsius.

Another notable patent involves a method for forming tungsten oxide films. This method includes applying an alkyl amine tungstate compound onto a substrate and subsequently removing a portion of the compound to create a tungsten oxide film. The process involves forming a solution of the alkyl amine tungstate compound in a solvent, which is then evaporated to leave a deposit. This deposit is heated to partially pyrolyze the compound, resulting in a tungsten oxide film that is denser and exhibits a color gradient, with regions of different colors that are electrochromic.
