We are surrounded by glass! This material has been greatly used for thousand years. More than 2000 years ago in ancient Egypt glass was used to manufacture bottles of perfume. So its first uses were primarily related to decoration and jewellery. The resear ...
High speed rotation of small rotors is needed more and more in many industrial applications. Classical examples are compact devices like scanners, gyroscopes, centrifuge units and so on. The key to achieve high rotating speeds is to have contactless bearin ...
In some applications, contacts between two devices are the first cause of dysfunctions. The aim of this paper is to transfer contactless power energy to add new functions to a tool (e.g., drill machine). A bidirectional communication is also needed. This i ...
In this paper an innovative micromachined passive flow regulator for implantable drug delivery systems is presented. The aim is to passively achieve a constant flow rate over a certain pressure range through linear variation of a flow resistance. This flow ...
This paper inquires into the exportability of the fatigue measurements made on standard test-specimen to wire electro- discharge machined flexures with thin cross sections (50 micrometers ). It describes the results of a set of fatigue measurements made on ...
This paper describes a detailed study of the behavior of the parallel spring stage having four circular flexure hinges of very thin cross-sections manufactured by wire electro-discharge machining. The state of the art recalls the abundant literature publis ...
MgB2 hollow wires have been produced with a new technique which uses a conventional wire manufacturing process but is applied to composite billets containing the elemental B and Mg precursors in an appropriate shape. The technique has been applied to the m ...
A multispeed testing method for obtaining tool-life parameters using radioactive tools has been developed. By suitable interpolation of the instantaneous rates of absolute wear measured for a number of discrete cutting speeds, the corresponding tool-life v ...
In some applications, contacts between two devices are the first cause of dysfunctions. The aim of this study is to transfer contactless power energy to add new functions to a tool (drill machine for example). A bi-directional communication is also needed. ...
A new, versatile architecture is presented for microfluidic devices made entirely from glass, for use with reagents which would prove highly corrosive for silicon. Chips consist of three layers of glass wafers bonded together by fusion bonding. On the insi ...
