Development of a distributed actuation device consisting of soft gel actuator elements
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002It is desirable that soft objects like organs are manipulated by soft actuation devices. This paper presents a newly developed device using a large number of actuator elements made of a soft gel material, which applies a distributed driving force on objects.

Anomalous behavior of bimorph consisting of conducting polymer gel in electrochemical doping
Synthetic Metals, 1994Summary form only given. Recently we have found the gel characteristics in the lightly cross-liked conducting polymers such as poly(3-alkylthiophene). The volume instability of conducting polymer gel has been found by changing solvent composition and temperature and also upon doping.

(Invited) Thixotropic Gel Electrolyte Consisting of Imogolite and Ionic Liquid
ECS Meeting Abstracts, 2018Electrolytes are fundamental materials that have been used in various industrial fields, for example, in batteries. Liquid electrolytes, though widely used, lack safety and moldability because of the inclusion of organic solvents and the inherent fluidity.

Dye-sensitized Solar Cells Consisting of CuI-containing Gels
Chemistry Letters, 2006Abstract CuI-containing gels for dye-sensitized solar cells are reported. CuI-containing gels consist of CuI, methylpropylimidazolium iodide, iodine, and gelators consisting of polyvinylpyridine and tetra(iodomethyl)benzene.

Extraction of sugar from a gel consisting of agar, sugar and water
Chemical Engineering Science, 1962Abstract A slab of a gel consisting of agar, sugar and water was extracted with a solution of sugar in water of smaller sugar concentration than the gel. The flow rate of the solution, the temperature and the concentration level were varied. The experimental results show that, for the circumstances chosen, the influence of the flow rate on the rate ...

Multi-DOF device for soft micromanipulation consisting of soft gel actuator elements
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003Presents a multi-degree-of-freedom (DOF) micro motion device developed using a soft gel actuator, ICPF. It is superior to conventional micromanipulators in softness and compactness. 3-DOF motion was realized by a parallel mechanism with 4 ICPF actuators, and 6-DOF motion was created by a 3-actuator mechanism. The 3-DOF device had a maximum displacement

A biochemo-mechanical system consisting of polymer gels with immobilized glucose dehydrogenase
Polymer Gels and Networks, 1997Abstract An attempt was made to construct a biochemo-mechanical system via the physical entrapment of glucose dehydrogenase (GDH) within a gel consisting of a crosslinked copolymer of N-isopropylacrylamide and acrylic acid. We observed that the gel with the immobilized GDH shrank when glucose as the substrate was added into an outer medium together ...

Anion responsive molecular valve consisting of poly(4-vinylpyridine) gel
Sensors and Actuators B: Chemical, 2013Abstract An anion responsive molecular valve comprised of poly(4-vinylpyridine) gel-coated Au mesh was developed. At pH 3 the valve closed when the concentration of anions such as Cl−, ClO4−, SCN−, and HSO4− was low, whereas automatically opened upon an increase in the concentration of anion due to collapse of the gel.

Journal of Materials Science, 1993
The dynamic viscoelasticity of polymeric composites consisting of silicone gel and polymethacrylic acid cobalt(II) salt (PMACo) particles was studied in d.c. electric fields. It was measured by applying sinusoidally varying shear strain or compressive strain to the composites.

Thermosensitive solutions and gels consisting of poly(vinyl alcohol) and sodium silicate
Materials Letters, 2007We have investigated the transparency for visible light of a poly(vinyl alcohol) (PVA) aqueous solution in the presence of sodium silicates (SS). The transparency of the aqueous solution dramatically changed by varying temperature despite that neither aqueous solutions of PVA nor SS is sensitive to temperature.
