Title: Innovations of Nicholas Dartnell in Gas Sensing Technology

Introduction

Nicholas Dartnell is a notable inventor based in Cambridgeshire, GB. He has made significant contributions to the field of gas sensing technology, holding a total of 4 patents. His work focuses on developing advanced gas sensor systems that can accurately detect and differentiate between various gases in different environments.

Latest Patents

One of Nicholas Dartnell's latest patents is a semiconductor gas sensor and method for sensing two or more gases using contact resistance and sheet resistance. This innovative gas sensor system is designed to measure a plurality of gases in an environment. The system comprises multiple gas sensors, each featuring a pair of electrodes separated by a semiconducting material. The resistivity of the semiconducting material changes in the presence of a first gas, while the contact resistivity between the electrodes and the semiconducting material changes in the presence of a second gas. By measuring the total resistivity of each gas sensor, the system can determine the presence and concentration of both gases.

Another significant patent is a gas sensor system that includes at least one first field effect transistor (FET) and at least one second FET, each with distinct source and drain electrodes. The different responses of these FETs to gases in the environment allow for the differentiation between gases, such as 1-methylcyclopropene and ethylene, particularly in locations where fruit is stored.
