Elastomeric conductive layer is the crucial component of flexible sensor, which transmits and quantifies external stimuli in form electrical signals. In this review, Feng co-workers comprehensively summarize recent advancements elastomeric polymers used to make layer, as well relationships between function, performance, application sensors (e319).

Sterilization (or sterilisation) is a term referring to any process that eliminates (removes) or kills all forms of microbial life, including transmissible agents (such as fungi, bacteria, viruses, spore forms, etc.) present on a surface, contained in a fluid, in medication, or in a compound such as biological culture media. Sterilization can be achieved by applying the proper combinations of h...

OBJECTIVES To compare the following over a period of 8 weeks: (1) force decay between thermoplastic (TP) and thermoset (TS) elastomeric chains; (2) force decay between light (200-g) and heavy (350-g) initial forces; and (3) force decay between direct chains and chain loops (stretched from one pin around the second pin and back to the first pin). MATERIALS AND METHODS TP and TS chains were obt...

Amaç:
 Elastomerik zincirlerin klinik kullanımı sırasında birçok avantajlarının olmasının yanısıra aktivasyon kuvvetinin zamanla farkedilir bir şekilde azalması en büyük dezavantajlarından biridir. Bu çalışmanın amacı; farklı elastomerik zincirlerde oluşan kuvvet kaybındaki değişimlerin incelenmesidir.
 
 Gereç ve Yöntem:
 Çalışmamız, 5 zincir grubundan oluşmuştur; Grup 1: A...

Introduction: Orthodontic treatments and brackets application with various ligature methods have increased worldwide, but the growth rate and mechanism of microorganism adhesion to these ligatures is not fully discovered. The current study aimed to compare the level of streptococcus mutans adhesion to three different ligation methods. Materials and Methods: This in vitro study was performed on...

We report a novel inkless soft lithographic fabrication protocol that permits uniform parallel patterning of hydrogen-terminated silicon surfaces using catalytic elastomeric stamps. Pattern transfer is achieved catalytically via reaction between sulfonic acid moieties covalently bound to an elastomeric stamp and a Boc-functionalized SAM grafted to passivated silicon. The approach represents the...

The Objet PolyJet 3D Printing process provides the ability to print graded materials featuring both stiff and elastomeric polymers. This capability allows for a variety of new design possibilities for additive manufacturing such as living hinges, shock absorbing casings, and integrated gaskets. Such design features typically rely upon the ability of traditional elastomers to experience large an...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Three-dimensional periodic structures have many applications in acoustics and their properties are strongly related to structural details. Here we demonstrate through simulations the ability to tune the phononic band gaps of 3D periodic elastomeric structures using deformation. The elastomeric nature of the material makes the transformation of the band gaps a reversible and repeatable process, ...
