Flexible Graphene Temperature Sensor

Technology Overview

This graphene-based temperature sensor is the ideal thermometer for large area sensing with fast response and low power consumption. Its graphene ultrathin layer works as a resistance temperature detector (RTD). The sensor is thin and lightweight and it features excellent chemical stability. It provides temperature data on the basis of averaging or mapping.

Technology Features & Specifications

  1. Thin, light-weight
  2. Flexible
  3. Use of carbon-based active material as opposed to expensive pure metallic layers used in conventional RTDs
  4. Large sensing area, from mm2 to m2
  5. Fast response due to low heat capacitance (final value depends on the selection ofinsulation material)
  6. Excellent heat dissipation (low self-heating) due to large surface area
  7. Possible deposition of active sensing material directly on surface of object-of-interest

Potential Applications

This technology is suitable for (but not limited to) the following applications:

  1. Temperature sensing of flexible surfaces/objects
  2. Sensor for rechargeable batteries
  3. Heat traces detection
  4. Mapping of temperature distribution
  5. Low heat capacity, ultra-fast heater
  6. Temperature compensation in general use of electric circuits

 

Some industries that this technology can be applied to are:

  1. Health care & life science
  2. Aviation
  3. Automotive
  4. Electronics
  5. Transport & logistics
  6. Energy management Process monitoring

Customer Benefits

When compared with conventional sensors, this graphene sensor technology is also interesting for those applications where one needs to detect, e.g. local overheating of device that does not have metal (or well-heat-conductive) surface. Here, a conventional sensor might fail as it measures in one particular place and as opposed to direct-surface measurement of large areas with graphene sensor.
