Microheaters are devices which are capable of rapid localised heating within a micro-scale region. The combination of high response and a compact architecture allows for the generation of temperature gradients, leading to the use of microheaters for a variety of applications such as in microreactors, and chemical and environmental sensors.
Conventional microheaters are generally rigid, opaque or both. The use of graphene as the heating element allows the microheater to be transparent and flexible, making it suitable for use in optical detection in lab-on-chip devices, wearable electronics, electronic skins and more.
This technology offers a transparent and flexible graphene-based microheater of a higher electrical resistance than conventional metallic heaters, and thus can be effectively powered by wearable energy harvesters. Through an optimised design, it is also able to achieve a uniform temperature distribution and an 80% higher heating temperature than a conventional graphene microheater.
This technology comprises of following features:
Depending on the requirements, the technology may be modified through geometrical and material alterations to achieve the best results.
This graphene microheater may be used in many applications, but not limited to the following:
