Title: Fred Wudl: Innovator in Electrochromic Devices

Introduction

Fred Wudl is a notable inventor based in Chester, NJ (US). He has made significant contributions to the field of electrochromic devices, holding a total of 3 patents. His work has advanced the understanding and application of materials in innovative ways.

Latest Patents

Wudl's latest patents include the development of solid electrochromic devices. These devices utilize ionic conductors, such as heteropoly acids, as the electrochromic material. The unique properties of these ionic conductors allow for the construction of devices with only two electrodes and the electrochromic material. When low voltages are applied between the electrodes, a color change occurs, such as from white to dark blue when phosphotungstic acid is used. Remarkably, cycle times as low as 100 milliseconds can be achieved, and these devices exhibit memory properties. Another significant patent involves the preparation of novel conjugatively linked tetrathiafulvalenes. This technique results in a molecule that includes two donor moieties, enabling the formation of charge transfer complexes with a band structure that surpasses the quasi one-dimensional structure found in currently known electrically conducting organic complexes.
