Sensor Development

Flexible/Stretchable electronics based on 2D materials

Future electronics technology will evolve from rigid substrate based devices to flexible/stretchable devices.

A wide variety of stretchable devices and systems has been successfully developed, including

stretchable conductors, sensors, light emitting diodes, photovoltaics, batteries, displays, and artificial skins.

Recently, emerging 2D materials such as graphene, boron nitride, and transition metal dichalcogenides

(TMDs) are attractive because of their outstanding electrical, mechanical, and optical properties,

which are ideal for flexible/stretchable electronics.

2D material gas sensor synthesis & 2D gas sensor

Two-dimensional (2D) materials have attracted significant attention owing to their unusual electronic and optical properties.

The discovery of graphene and other two-dimensional (2D) materials, due to their maximum surface to mass ratio, low noise,

high sensitivity, and increased selectivity, determined a paradigm-shift in the research and technology of gas sensors

Photolithography technique for the fabrication of devices from CVD grown 2D materials

Fabrication of field-effect-transistor (FET) using 2D materials without aqueous solution - most 2D materials

are vulnerable to water base solution (Van-der-Waals force between MoS2 and hydrophilic substrate, fig. c)
