Publication number: 20090152513Abstract: Polar molecules dominated electrorheological fluids mainly comprising a mixture of dispersed phase of solid particles and/or dispersing liquid medium. The dispersed phase solid particles, on the surface, or the liquid dispersing medium contain polar molecules or polar groups, the dipole moment of which is 0.5-10 deb and the size is between 0.1 nm and 0.8 nm. Dispersed phase solid particles are spherical or nearly spherical, of which the size is 10-300 nm and dielectric constant is higher than 50. The conductance rate of the liquid dispersing medium is lower than 10?8 S/m, and the dielectric constant is lower than 10. The PM-ER fluids possess the characteristics of high yield strength, high dynamic shear strength, low leakage current, the linear dependence of yield strength on electric field, and high yield strength at low electric field, etc. The yield strength improves to almost 100 times of that of ordinary ER fluids and reaches to more than 200 Kpa.Type: ApplicationFiled: December 15, 2008Publication date: June 18, 2009Applicant: INSTITUTE OF PHYSICS, CHINESE ACADEMY OF SCIENCESInventors: Kunquan Lu, Rong Shen, Xuezhao Wang

Patent number: 7422709Abstract: An electromagnetic rheological (“EMR”) fluid (18) broadly includes a conducting medium (22) and a plurality of micronparticles (24) suspended in the medium (22). Each of the micronparticles (24) includes a magnetically permeable core (26), an electrically insulating coating (28) surrounding the core (26), and a conductive winding (30) at least partially wound around the core (26) so that the coating (28) is disposed between the winding (30) and the core (26). An apparatus (10) constructed in accordance with a preferred embodiment of the present invention broadly includes a deformable membrane (12), a pair of polar opposed plates (14 and 16) coupled to the membrane (12), the EMR fluid (18) filling the membrane (12) and being in communication with a current source (20). Current flowing through adjacent windings (30) induces magnetic fields in the corresponding micronparticles (24) that mutually draw the adjacent micronparticles (30) causing them to move together into a north pole-south pole alignment.Type: GrantFiled: May 23, 2005Date of Patent: September 9, 2008Inventor: Crosby Gernon
