In the infrastructure of the future, based on intelligent computerized systems and control and monitoring devices, the smart home is part of the Internet of Things (IoT). However, in addition to the ...need to address energy consumption, the widespread adoption of smart homes may also exacerbate the growing problem of increasing amounts of non-recyclable e-waste from IoT devices. Compared to synthetic plastics, biopolymers offer many unique advantages such as robust structure, light weight, mechanical flexibility, biocompatibility, biodegradability and renewability. Biopolymers, which are abundant in natural products such as cellulose, silk fibroin, polylactic acid, chitosan, collagen, keratin, alginate, starch and gelatin, have great promise for the production of environmentally friendly Internet of Things devices. They are ideal candidates for the use of low-temperature sol–gel coating and ink-printing processes to facilitate the development of low-cost, large-area flexible electronic devices. This work presents developments known from the literature, as well as the results of original research on the use of biopolymer materials to create flexible, wearable and textile electronic devices, such as sensors, energy storage devices and nanogenerators, soft hydrogel actuators and wireless communication devices that are promising for the Internet of Things but have not yet been implemented in smart homes.
Graphical Abstract
In this article, effective 3D printing technology of smart biologically active polymeric hydrogel transdermal nanomaterial's based on gelatin and sodium alginate, modified by humic acids, were ...researched. It is shown that the application of new smart biologically active polymeric hydrogel transdermal nanomaterial's based gelatin and sodium alginate modified by humic acids allows improving the skin moisture - lipid balance. Smart biologically active polymeric hydrogel transdermal nanomaterial's patches were produced using a micromolding technique where an FDM 3D printer was used to print the master mold. Form modeling was done in Autodesk's Fusion 360. The resulting 3D model was processed by a slicer to receive a file with commands for a 3D printer. So, designed 3D printing technology of smart biologically active polymeric hydrogel transdermal nanomaterial's based on gelatin, sodium alginate, modified by humic acids, are transdermal materials with good properties.
