“…The fundamental principles of piezoelectricity in biopolymers are based on their complex dipolar properties and dipole-dipole interactions, facilitated by complex networks of hydrogen bonds and semi-crystalline structure that exhibit varying levels of self-assembly and hierarchical organization [47]. Medical actuators based on the inverse piezoelectric effect of biopolymers such as polylactic acid are described in [54][55][56].…”

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.

“…They possess key attributes, such as flexibility, lightweight nature, effective processability through polymer processing, adaptability in design, and recyclability. This flexibility and adaptability render polymer composites particularly well-suited for applications such as sensors and energy harvesting devices [ 1 , 2 , 3 , 4 , 5 ]. Sensors constructed from these materials exhibit sensitivity to mechanical stimuli and can be integrated into self-powered systems and smart devices for various technical applications [ 2 ], including medical diagnostics [ 3 ], structural health monitoring [ 4 ], and wearable applications [ 5 ].…”

This study reports the possibility of using biaxially oriented polyethylene terephthalate (BOPET) plastic packaging to convert mechanical energy into electrical energy. Electricity is generated due to the piezoelectricity of BOPET. Electricity generation depends on the mechanical deformation of the processing aids (inorganic crystals), which were found and identified by SEM and EDAX analyses as SiO2. BOPET, as an electron source, was assembled and tested as an energy conversion and self-powered mechanical stimuli sensor using potential applications in wearable electronics. When a pressure pulse after pendulum impact with a maximum stress of 926 kPa and an impact velocity of 2.1 m/s was applied, a voltage of 60 V was generated with short-circuit current and charge densities of 15 μAcm−2 and 138 nCm−2, respectively. Due to the orientation and stress-induced crystallization of polymer chains, BOPET films acquire very good mechanical properties, which are not lost during their primary usage as packaging materials and are beneficial for the durability of the sensors. The signals detected using BOPET sensors derived from pendulum impact and sieve analyses were also harvested for up to 80 cycles and up to 40 s with short-circuit voltages of 107 V and 95 V, respectively. In addition to their low price, the advantage of sensors made from BOPET plastic packaging waste lies in their chemical resistance and stability under exposure to oxygen, ultraviolet light, and moisture.
