Role of Liquid Metal in Flexible Electronics and Envisage with the Aid of Patent Landscape: A Conspicuous Review
Source abstract
Abstract
Wearable`s become most widely used in the medical field to assess and monitor human body conditions even from remote locations. So, it should be weightless as well as functional at various temperature ranges. It is mandated that it should be functional with ultra-sensitiveness. The proper selection of conductive elements should be part of the measuring device. Based on these criteria, this review article is articulated. The effect conductor is metal, but metal is heavier, wearable should be slick thereby, the best material is liquid metal. So, the scope and implications of the liquid metal in flexible electronics are consolidated. Furthermore, the future scope of the wearable is assessed with the aid of patent landscape analysis, as a known fact is updated faster than other databases. As well-identified few technologies that have been applied as patents, it might have better growth owing to its technological advancements. Graphical Abstract
