Reduced Graphene Oxide-Silver Nanocomposite Films for Temperature Sensor Application

IPTeL Tracking ID: MPS-IAP-2016-010

Researchers from Indian Institute of Science have fabricated nanocomposite of reduced graphene nanosheets and silver nanoparticles for sensor applications, particularly compact size, low cost and flexible temperature sensors.

BACKGROUND

Temperature sensors contain elements with the property of temperature-dependent electrical resistance (for example, thermistor). Though conventional temperature sensors have higher sensitivity, they exhibit lower response time and limit their temperature range. Recently, nanoscale devices have been attractive candidates for temperature sensing.

TECHNOLOGY

The invention relates to a nanocomposite of reduced graphene nanosheets and silver nanoparticles for temperature sensing applications.

Key features:

  • Flexibility in terms of stretchability and bendability
  • Cost effective and simplified fabrication process
  • Tailor made resistance values
  • Reduced size of the device and hence packaging requirement is least.
  • Mass production at low cost

The same sensor can be applied for strain, pressure, force, acoustic, speed, humidity, gas sensing and biological sensing.
