About this technology

Overview

Oxygen (O 2 ) sensors are used in a wide array of applications, including electronic fuel injection and emissions control in the automotive industry, for monitoring oxygen levels in controlled environments, such as in space craft or space suits, for oxygen monitoring in medical and pharmaceutical applications, and many more. Traditional oxygen sensors, including potentiometric and amperometric sensor designs, have significant drawbacks, as metal oxide gas sensors require high temperature operation of about 300°C, and suffer from high power consumption. NASA Ames Research Center has developed novel oxygen sensors made of a hybrid material comprising graphene and titanium dioxide (TiO 2 ) that is capable of detecting O 2 gas at room temperature and ambient pressure. The sensors have fast response and recovery times and can also be used to detect ozone. The sensors can be integrated into wearable-sized Internet of Things (IoT) devices.
