Enhanced-performance bio-triboelectric nanogenerator based on starch polymer electrolyte obtained by a cleanroom-free processing method

Bio‐Derived Natural Materials Based Triboelectric Devices for Self‐Powered Ubiquitous Wearable and Implantable Intelligent Devices

“…Starch as an attractive raw material for biodegradable polymers [190][191][192] is not only widely used in bioplastics, [183,[193][194][195] e.g., as disposable flexible substrates, shopping bags and packaging films of food, but also shows potential as drug delivery carrier and the triboelectric materials for energy harvesting and self-powered sensors. [95,105,196,197] For instance, Avval et al [196] reported a starch polymer-based drug delivery carrier for controlled in vitro release of cephalexin antibiotic. Zhu et al [105] developed a starch paper-based self-powered human perspiration triboelectric sensor for detecting the amount of absorbed water.…”

Biotriboelectric Nanogenerators: Materials, Structures, and Applications

“…Vela's work describes a low‐cost bio‐TENG using a starch‐based microstructured film as a triboelectric dielectric material. [ 28 ] The starch is derived from potatoes and, after dissolution, is poured onto the surface of the sandpaper to obtain a starch film with a microstructure. This process method does not change the chemical composition and group distribution of starch molecule (Figure 2g).…”

A Flexible, Recyclable, and High‐Performance Pullulan‐Based Triboelectric Nanogenerator (TENG)

“…Jiang et al [25] developed various fully bioabsorbable natural-materials-based TENGs, which were used as an in vivo voltage source to accelerate the beating rates of dysfunctional cardiomyocyte clusters and improve the consistency of cell contractions. [23] Therein, many other polysaccharides [26][27][28][29] with unique properties are supposed to be researched and optimized for the better electric performance and bioapplications of the bio-TENGs.Pullulan, produced by the yeast-like funguses, [30] is a linear and unbranched micro-organismal polysaccharide with maltotriose repeating units connected by α−(1 → 6) glycosidic bonds. [23] Therein, many other polysaccharides [26][27][28][29] with unique properties are supposed to be researched and optimized for the better electric performance and bioapplications of the bio-TENGs.…”

“…Generally, the natural biomaterials, prepared into bio-TENGs, are mainly divided into two strategies, including natural proteins and polysaccharides. [23] Therein, many other polysaccharides [26][27][28][29] with unique properties are supposed to be researched and optimized for the better electric performance and bioapplications of the bio-TENGs.Pullulan, produced by the yeast-like funguses, [30] is a linear and unbranched micro-organismal polysaccharide with maltotriose repeating units connected by α−(1 → 6) glycosidic bonds. [31] In the past several decades, pullulan and its derivatives have been widely applied in biomedical, [31] food, [32] pharmaceutical, [33] and petroleum industries [34,35] with the properties of nonmutagenicity, water solubility, editability, [36] nontoxicity, biodegradation, [37] biocompatibility, nonimmunogenicity, and noncarcinogenicity.…”
