The transient plane source (TPS) method is a relatively newly developed approach for thermal conductivity measurement. Compared with the steady-state method, it fast, and applicable to either solid, liquid or gas state materials; therefore, has gained much popularity in recent years. However, during measurement, measured power influenced by heat capacity of electrical isolation films as well resistance change metallic thin wire TPS probes. This further influences measurement precision....
Air pollution has been correlated to an increasing number of cases human skin diseases in recent years. However, the investigation tissues received only limited attention, point that there are not yet satisfactory modern detection technologies accurately, noninvasively, and rapidly diagnose at epidermis dermis levels. In order detect analyze severe such as melanoma, a finite element method (FEM) simulation study application laser-generated surface acoustic wave (LSAW) technique is developed....
A hybrid atomic force microscopic (AFM) measurement system combined with white light scanning interferometry for micro/nanometer dimensional is developed. The based on a high precision large-range positioning platform nanometer accuracy which interferometric module and an AFM head are built. compact developed using self-sensing tuning fork probe. need no external optical sensors to detect the deflection of cantilever, saves room head, it can be directly fixed under system. To enhance...
Ultra-short cantilevers are a new type of cantilever designed for the next generation high-speed atomic force microscope (HS-AFM). have smaller dimensions and higher resonant frequency than conventional AFM cantilevers. Moreover, their geometry may also be different from beam-shape or V-shape. These changes increase difficulty determining spring constant ultra-short cantilevers, hence limit accuracy precision measurement based on HS-AFM. This paper presents an experimental method to...
In this paper, a polyvinylidene fluoride (PVDF) piezoelectric transducer was developed to detect laser-induced surface acoustic waves in SiO(2)-thin film-Si-substrate structure. order solve the problems related to, firstly, position of probe, and secondly, fact that signals at different points cannot be detected simultaneously during detection process, four-quadrant wave PVDF designed constructed for purpose detecting excited by pulse laser line source. The experimental results comparison...
The present paper presents the design and development results of a system setup for measuring Young’s modulus thin films by laser-induced surface acoustic waves based on integration two detection methods, namely, piezoelectric transducer differential confocal detection, which may be used conducting consecutive or simultaneous measurements. After demonstrating capabilities each approach, it is shown how, depending wider range applications, sample materials measurement environments, developed...
Laser-induced Surface Acoustic Waves (LSAWs) has been promisingly and widely used in recent years due to its rapid, high accuracy non-contact evaluation potential of layered thin film materials. For now, researchers have applied this technology on the characterization materials' physical parameters, like Young's Modulus, density, Poisson's ratio; or mechanical changes such as surface cracks skin feature a melanoma. While so far, little research done providing practical guidelines pulse laser...
There are tasks such as remote exploration and manipulation of explosive objects where high dexterity, accuracy, practicality necessary. The proposed haptic hand exoskeleton design uses displacement sensors in both flexion-deflection well abduction-adduction to replicate the operator's main three fingers' motion teleoperate a slave robotic for disassembling disposal objects. novel design, component selection, computer-aided virtual prototype were developed tested.
The design and analysis of highly accurate measurement systems positioning devices play a strategic key role in such application fields as aeronautics, machine tools, microelectromechanical systems, life sciences needing increasingly effective noncontact testing, detailed characterization, performance. This makes it vital for us to update our knowledge with new contributions involving both scientific cuttingedge investigations the latest industrial developments. special issue addresses...
