Book excerpt: The future success in healthcare is now strictly entangled with the advances in tissue engineering and bio sensing technologies. Solutions to overcome current limitations in this multidisciplinary field have been actively pursued which has resulted in new materials and properties. Stretchable electronics with tunable mechanical, chemical and electrical properties which are compatible with 3D printing process are highly demanded for biomedical, tissue engineering and health monitoring applications. However, current existing studies have been rather failed to be used in clinics and industries. Cost efficiency and facile preparation method are other dissuasive factors for further achievements. Introducing self-healing properties to the elastic electronics can ensure higher safety and be helpful for bio mimicking purposes. Hydrogels enable mimicking most tissues of human and animal bodies due to their tissue like properties. With tuning different mechanical, physical, chemical and electrical parameters of hydrogels, one can develop bio mimicking hydrogels for countless applications. Herein, three approaches are represented to synthesize conductive nanocomposites applicable in biomedical sensing for health monitoring systems, electric skin and artificial organs. Briefly, in chapter 2, an innovative strategy is presented to fabricate a CNT-based stretchable strain gauge which can detect high strains with high sensitivity. Contrary to some other sensors in which the conductive particles are required to be deposited on elastomer substrates, in this design, CNTs are distributed uniformly on the entire substrate material. Beside, a facile and very unique approach is presented to reach CNTs with aligned arrangement. Another feature of our sensor is the ability to recognize the humid changes with a high sensitivity and fast resistance response capable of monitoring the human breathing. The moldable and plastic material of gum sensors allow a very uniform dispersion of nanotube solution and the ability of being folded leads to a good alignment of nanotubes with good conductivity. In chapter 3, a mechanically and electrically self-healing hydrogel was synthesized with pressure and extension sensitive features, introducing a promising candidate for wearable sensors. The hydrogel was prepared with physically and chemically cross-linked networks through a two-step synthesis. Another feature of our hydrogel is the injectability which enables to print a CSH hydrogel for the first time. The non-covalent and reversible bonds can be disrupted and reformed by an introduction and removal of an external force, respectively. Furthermore, we revealed that the current CSH hydrogel has the ability to monitor human motions with fast resistance response. In chapter 4, a new class of tunable hydrogels was developed based on poly vinyl alcohol. A new method of gelation was introduced which enables both layer by layer and 3D printing fabrications. PVA hydrogels perform shape memory and artificial muscle behav-iour and can retrieve 90% of plastic deformation upon adding water. Strong mechanical and stable chemistry of this hydrogel led to new injectable electronics. This material can be an alternative for microfluidic chip and be introduced as new class of catheters. Appli-cations of this new approach are discussed. Biocompatibility, protein and bacterial anti-fouling and blood-compatibility of this material are confirmed with in vitro experiments which opens new gates for the field of biomaterials.

Download or read book Application of Nanomaterials for Wearable Electronics written by Yuyan Gao and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skin-integrated, wearable electronics play important role in human healthy monitoring. Conductive thin films can be sensors, connecting wires, antennas in wearable electronics. This dissertation focused on the new, low-cost, easy-fabricated approaches of the sintering metal nanoparticles to form conductive thin films for wearable sensors. Experimental and numerical characterization of nanomaterial-based wearable electronics are also discussed. Low-cost, fast, and large-scale fabrication of functional sensors on 3D surfaces is of great interest to wearable electronics and Internet-of-Things (IoT) smart sensors. Traditional photolithography-based procedures are expensive, time-consuming with limited production capacity. In chapter 2, we present a new mass transfer strategy by photonic sintering of Zinc nanoparticles (Zn NPs) to fabricate Zinc conductive sensors on flat/curvilinear surfaces. The Zn NPs on temporary substrate were locally heated up and evaporated under the exposure of the intense pulsed light. The evaporated Zn NPs then transferred to the target 3D surface to form a conductive Zn thin layer. Functional sensors on glass beakers, contact lens, and other substrates demonstrated this mass transfer strategy as applications. Skin bioelectronics can collect various physiological signals directly from the human skin. However, the signals are sometimes unsteady due to the deformation of skin (e.g., stretching, compression, bending) and body motions. In chapter 3, we report an easy-fabricated, ease-of-use, water-dissolvable, single-layer, ultra-conformal, artifact-free, multifunctional skin sensor for high-quality human physiological data collection. The Cu core-Ag shell nanoparticles coalesced at 50°C with the mixture of montmorillonite (MMT), polyvinyl alcohol (PVA), glycerol, and polyethylene glycol (PEG) solution to become a highly conductive membrane. By spraying small amount of water before sticking, the good conformal contact formed and the contacting impedance dramatically reduced accompanying with the improved stability of the data. This highly conductive, ultra-conformal, easily removable, single layer of membrane can be used as different kinds of wearable sensors, wire connections on human bodies for steady physiological sensing. The single-layer combination of functional conductive nanoparticles and supporting layer simplifies fabrication complexity and expands the possibility for the material design of wearable electronics. The outstanding mechanical, electrical, and optical properties of graphene make it a hot nanomaterial and the graphene is integrated into flexible and wearable electronics. Chemical Vapor Deposition (CVD) is a common method to fabricate single layer of graphene. However, defects include grain boundaries during the CVD process weakened the performance of graphene. In chapter 4, we demonstrate a molecular dynamic simulation using phase crystal modeling to study the mechanical properties of graphene with grain boundary defects.
