Additive manufacturing has emerged as a transformative method for fabricating monolithic, assembly-free tactile sensors. However, the operational performance of these sensors depends not only on the intrinsic properties of the base functional materials but also heavily on the structural architecture of the sensors. Modern 3D printing technologies enable precise control over this architecture...
Home-based resistance training has grown rapidly as a setting for unsupervised exercise, motivating wearable systems that provide automated feedback such as form correction, repetition counting, and load adjustment. Delivering that feedback first requires detecting which lower-limb movement the user is performing, and surface electromyography (sEMG) is well suited to this because each exercise...
Abstract. This study presents a structural layer separating method using centrifugation to isolate high-quality, transparent few layer reduced graphene oxide (rGO) from thick black rGO cluster residues. The separated supernatant fractions named as layers 1–4 were drop-casted onto rigid glass and flexible Polyethylene Terephthalate (PET) substrates. High power microscopy con-firmed that the top...
Improving optical absorption in the active layer is one of the key approaches to enhancing solar cell performance. Surface structuring has been recognized as an effective strategy to reduce optical losses and increase light trapping within the absorber layer. This study presents a simulation study of active layer surface structuring for enhanced optical absorption in solar cells using the...
Abstract. Background: Non-invasive hemoglobin (Hb) measurement has gained considerable interest as a painless alternative to blood sampling for anemia screening and continuous monitoring. Despite rapid advances in spectroscopy and optical sensing, clinical implementation remains limited by inconsistent diagnostic performance and heterogeneous validation methods.
Methods: This systematic...
Thin-film Barium Strontium Titanate (BST)-based light sensors have significant potential for application in various optical detection systems due to their excellent dielectric characteristics and photoresponsive properties. However, the development of these sensors has primarily focused on material characterization and sensing performance, while the mechanical aspect, particularly the...
This study presents a systematic investigation into the chemical etching kinetics, geometric optimization, and evanescent field dynamics of unclad multimode optical fibers for refractive index sensing applications. Cladding removal was controlled using hydrofluoric acid (HF) at distinct concentrations of 30.6% and 49%. Experimental results demonstrate that the etching rate is highly dependent...
Strontium titanate (SrTiO₃) is a perovskite oxide with excellent dielectric and optical properties, making it a promising material for photocatalytic, sensing, and optoelectronic applications. This study investigates the effect of Ferrum (II) acetate doping on the crystal structure and optical properties of SrTiO₃ ceramics synthesized using the conventional solid-state reaction method. Ferrum...
