Pagina 34 - M is the maximum moment at the built-in end and / is the moment of inertia of the cross-section of the beam.
Pagina 294 - IPMNC actuation/sensing phenomena using linear irreversible thermodynamics: When static conditions are imposed, a simple description of mechanoelectric effect is possible based upon two forms of transport: ion transport (with a current density, J, normal to the material) and electrophoretic solvent transport.
Pagina 27 - Styrene/divinylbenzene-based polymers in which the ionic groups have been substituted from the phenyl rings where the nitrogen atom is fixed to an ionic group. These polymers are highly cross-linked and are rigid. In perfluorinated sulfonic acid polymers there are relatively few fixed ionic groups. They are located at the end of sidechains so as to position themselves in their preferred orientation to some extent. Therefore, they can create hydrophilic nano-channels, so called cluster networks [Gierke...
Pagina 330 - Upon electrical activation, this wiring configuration allows the fingers to bend either inward or outward similar to the operation of a hand and thus close or open the gripper fingers as desired. The hooks at the end of the fingers represent the concept of nails and secure the gripped object that is encircled by the fingers.
Pagina 223 - Exact expressions are given relating the deformation characteristics of the gel to the electric field strength or voltage gradient, gel dimensions and other physical parameters such as the resistance and the capacitance of the gel strip. It is concluded that direct voltage control of such nonhomogeneous large deformations in ionic polymeric gels is possible.
Pagina 168 - The syringe was tilted at approximately l5" from horizontal so that a small drop was maintained at the capillary tip, due to the surface tension of the solution.
Pagina 293 - Hz. Such direct mechanoelectric behaviors are related to the endo-ionic mobility due to imposed stresses. This...
Pagina 155 - Furthermore, it has been experimentally observed that swelling and shrinking of ionic gels can also be induced electrically. Thus, direct computer control of large expansions and contractions of ionic polymeric gels by means of a voltage gradient appears to be possible. These gels possess an ionic structure in the sense that they are generally composed of a number of fixed ions (polyions) pertaining to sites of various polymer cross-links and segments and mobile ions (counter ions or unbound ions)...
Pagina 274 - Now from equations (16)-(28) it is clear that the nonhomogeneous force field and the curvature in bending of ionic gels can be electrically controlled by means of an imposed voltage v across the gel.
Pagina 222 - ... has also been discussed recently by Li and Tanaka [5], De Rossi, Chiarelli, Buzzigoli, Domenici, and Lazzeri [6], Caldwell and Taylor [7], De Rossi, Kajiwara, Osada, and Yamauchi [8], Segalman, Witkowski, Adolf, and Shahinpoor [9], [10], and Harland and Prud'homme [11]. Hamlen, Kent, and Shafer [12] were the first to report that contraction and swelling of these gels can also be obtained electrically by placing fibrous samples of PAA-PVA in an electric field. One of the earlier mathematical modeling...
