Single-Walled Carbon Nanotubes based sensors and amplifier circuit integrated on flexible substrates

Abstract

Single-Walled Carbon Nanotubes (SWCNTs) have been shown to be a promising candidate for flexible electronics, especially logic circuits. However, very little study on SWCNT based analog circuit elements, such as amplifiers and comparators, on flexible substrates has been reported. For practical applications, fully functional flexible electronic devices must have an analog input circuitry to achieve appropriate functionalities. In this work, we demonstrate a resistive SWCNT gas sensor integrated with an amplifier circuit on flexible substrate to detect and amplify the sensing signals.
