Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic components on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester [1] film.
The development of Flexible Surface Acoustic Wave (SAW) devices has been a significant driver in the advancement of wearable technology and microfluidic systems. These devices are typically fabricated on polymer substrates, such as Polyethylene Naphthalate (PEN) and polyimide, and utilize sputtering deposition of materials like AlN and ZnO. [44]
Promoted by the demand for wearable devices, graphene has been proved to be a promising material for potential applications in flexible and highly sensitive strain sensors. An environment-friendly and cost-effective method to fabricate large-area ultrathin graphene films is proposed for highly sensitive flexible strain sensor.
[1] [2] [3] Thus, it exhibits potential for applications in optics and electronics especially for the development of wearable devices as flexible substrates. More importantly, the optical absorption rate of graphene is 2.3% in the visible and near-infrared region.
Flexible electronics are polymers or other flexible materials (e.g. silk, [223] pentacene, PDMS, Parylene, polyimide [224]) printed with circuitry; the flexibility allows the electronics to bend. The fabrication techniques used to create these devices resembles those used to create integrated circuits and microelectromechanical systems (MEMS).
Wearable technology is any technology that is designed to be used while worn.Common types of wearable technology include smartwatches and smartglasses.Wearable electronic devices are often close to or on the surface of the skin, where they detect, analyze, and transmit information such as vital signs, and/or ambient data and which allow in some cases immediate biofeedback to the wearer.
System devices: The sensors used in WBAN would have to be low on complexity, small in form factor, light in weight, power efficient, easy to use and reconfigurable. Further, the storage devices need to facilitate remote storage and viewing of patient data as well as access to external processing and analysis tools via the Internet.
