Background Cardiovascular patient-specific phantoms can improve patient care through testing and simulation. However, materials like silicone 3D-printing polymers differ mechanically from biological tissues. Agilus30 Clear, the primary material for 3D-printed phantoms, is much stiffer, nearly isotropic, lacks strain-hardening behavior. To overcome these challenges, a novel 3D voxel-printing approach may provide an effective solution. Methods/aim This study aimed to explore applicability of...
This paper introduces a titanium-based planar ultrasonic microscalpel. The concept of silicon-based transducers has already been proven, but they are not yet suitable for clinical use due to material failure. main objective this work was develop smaller, lighter, and more cost-effective scalpel that could be used as an alternative or supplementary device current surgical instruments. Various prototypes were fabricated characterized, differing in bonding by three epoxy adhesives two solder...
Abstract Objectives To compare ultrasonic scaler prototypes based on a planar piezoelectric transducer with different working frequencies featuring titanium (Ti-20, Ti-28, and Ti-40) or stainless steel (SS-28) instrument, commercially available (com-29) in terms of biofilm removal reformation, dentine surface roughness adhesion periodontal fibroblasts. Materials methods A multi-species was formed specimens slices. Thereafter were instrumented scalers pocket model left untreated (control)....
Caries and periodontitis affect the majority of adults during their lifetime. Piezoelectric ultrasonic scalers offer great benefits prevention treatment periodontal diseases. Our group developed a novel scaler based on planar piezoelectric transducer. However, similar to other configurations, transducer's characteristics are strongly influenced by operation conditions. In this study, we investigated influence driving voltage amplitude loading force applied using physical calculus models...
This study investigated the magnitude, direction, and temporal aspects of force applied during instrumentation with a piezoelectric ultrasonic periodontal scaler, compared this recommendations in literature, assessed influence profession (dentist or dental hygienist) calculus hardness.

In previous work it was shown that Ionic Liquids as active substances in thermoelectric generators have the potential to reduce thermal conductivity compared Solid State materials used conventional TEGs. Furthermore, observed Seebeck coefficient could be significantly increased. After a large variety of experiments, appears remaining bottleneck coming high performance TEGs is, first finding ILs with increased negative coefficient, and, second sufficient current extraction. Looking at...
