Title: An Insight into Inventor David Scott Ashby

Introduction

David Scott Ashby is an innovative inventor based in Livermore, California, recognized for his contributions to advanced battery technology and electronic devices. With a total of two patents under his name, Ashby is making notable strides in the field of ionogel technology.

Latest Patents

Ashby's recent patents include the development of ionogel-based batteries and an ionogel liquid exchange mechanism. An ionogel is created from a mixture of precursors, a catalyst, and an ionic liquid to form a sol-gel. This process results in a solid-phase matrix containing pores filled with the ionic liquid. By employing thermal or vacuum drying, the gel becomes a solid-state ionogel, retaining the ionic liquid within. The ionogel can then be immersed in a liquid electrolyte, which, upon dissolving into the ionic liquid, creates a new ionogel version with the liquid electrolyte stored within its pores.

His other significant invention is the thermally sensitive ionic redox transistor. This device consists of a channel, a reservoir layer, and an electrolyte layer strategically placed between them. The ion concentration within the channel changes the conductance, while the electrolyte layer experiences a state change when it reaches a specific temperature. Below this transition temperature, ions remain largely immobile, enabling control of ionic movement across the electrolyte layer upon applying voltage. When cooled below the transition temperature, ions become trapped due to the loss of ionic conductivity in the electrolyte layer, allowing the state of the transistor to be determined by measuring channel conductance.
