Non-contact measurement method of mechanical stiffness for high revolutionary speed precision fluid dynamic bearing rotors
Microsystem Technologies - Tập 16 - Trang 233-240 - 2009
Mechanical properties of rotors supported by fluid dynamic bearings (FDBs) cannot be directly measured because most of the mechanical properties of FDBs become active only when the rotors are in revolutionary motion. A typical example is the measurement of mechanical stiffness of the rotors that are used for hard disk drives. A popular measurement method so-called pitch modes requires the rotor to...... hiện toàn bộ
Actuator – sensor technology on “electronic grade” diamond films
Microsystem Technologies - Tập 5 - Trang 38-43 - 1998
Thermal microheaters as used for example in thermal ink print heads contain a variety of materials, the heater itself is commonly based on refractory metals. Here, a novel concept based on diamond as a multifunctional material is proposed and demonstrated. In this concept, diamond serves as an insulating substrate, a metal-like heater and as a temperature sensor. Superheating of water could be ac...... hiện toàn bộ

Locally resolved stress and strain analysis of sinter-joined micro valves using synchrotron X-ray diffraction and conical slit apertures
Microsystem Technologies - Tập 21 - Trang 1787-1795 - 2014
For assessing the quality of the joining area as well as researching the influence of joining parameters in combination with different materials, the principal stress components of sinter-joined micro valves were analysed. Transmission experiments have been conducted at the high-energy material science (HEMS) beamline P07 at PETRA III, DESY. Due to the dimensions of the samples, a high spatial res...... hiện toàn bộ

Effect of surface on nano-beam mechanical behaviors: a parametric analysis
Microsystem Technologies - Tập 27 - Trang 665-672 - 2020
In this paper, effect of surface, including its elasticity, residual stress and density is investigated on the nano-beam stiffness and mass analytically. To this aim, the governing equation of the nano-beam dynamic behavior is extracted utilizing Gurtin–Murdoch’s theory and Euler–Bernoulli hypothesis which incorporates the surface effects. Effect of surface parameters on nano-beam lumped mass and ...... hiện toàn bộ
Rapid soda-lime glass etching process for producing microfluidic channels with higher aspect ratio
Microsystem Technologies - Tập 20 - Trang 1905-1911 - 2013
This paper presents a simple method to produce microfluidic channels in soda-lime glasses with the aspect ratio >0.5 utilizing a modified wet etching protocol. A low-cost positive photoresist (PR) layer is used as the etching mask for the wet etching process. Prior to the PR and primer coating procedure, a UV activation process is adopted for enhancing the binding strength of the hexamethyldisilaz...... hiện toàn bộ
Influence of thermal wave emitted by the cellular devices on the human head
Microsystem Technologies - Tập 25 - Trang 413-422 - 2018
In this work, a mathematical model of three layers system represents how the external thermal shock passing through the three layers of the head: skin, bone, and brain. In this model, we will take into account the internal heat source generated within the human head from the chemical reactions of the tissue and the lag-time to study the response time of the tissue takes due to the perturbation.
