An electromagnetic wave absorbing thermally conductive composition contains a matrix resin component, metal soft magnetic particles, and thermally conductive particles. The metal soft magnetic particles are carbonyl iron particles and are present in an amount of 30% by volume or more when the electromagnetic wave absorbing thermally conductive composition is a population parameter. A value of an imaginary part (μ″) of relative permeability of the electromagnetic wave absorbing thermally conductive composition is 0.9 or more in at least some bands in a frequency range of 18 to 26.5 GHz. The electromagnetic wave absorbing thermally conductive composition in the form of a sheet has a thermal conductivity of 2.0 W/m.Math.K or more in the thickness direction. A sheet of the present invention incudes the above composition in the form of a sheet. Thus, the present invention provides the electromagnetic wave absorbing thermally conductive composition and its sheet that can increase the value of the imaginary part (μ″) of relative permeability in a frequency band of 18 to 26.5 GHz, efficiently absorb electromagnetic wave noise in this frequency band, and also have a high thermal conductivity.

A magnetic-induced stiffness changed soft robot drive module includes magnetic-induced stiffness changed layer, two-degree-of-freedom pneumatic driver, magnetic core and sealing fixing device. The magnetic-induced stiffness changed layer and two-degree-of-freedom pneumatic driver are printed and formed. The magnetic core can be deformed together with the driver, and a magnetic field can be generated when it is energized. After the magnetic core is installed into the two-degree-of-freedom pneumatic driver, then assembled with the sealing fixing device, a soft robot drive module with one end fixed is finished. The magnetic-induced stiffness changed layer has the fast, reversible and controllable stiffness adjustment ability under the action of electromagnetic field. As its hardness is greater than that of the two-degree-of-freedom pneumatic driver and its position is outside the air cavity, the two-degree-of-freedom pneumatic driver can be restricted from over-expansion and over-extension in the axial direction, making its pneumatic bending deformation controllable.

A window includes a coating layer including a front surface, a rear surface, a first region having a constant distance between the front surface and the rear surface in a thickness direction, and a second region in which a distance between the front surface and the rear surface reduces in a direction away from the first region; and a bezel layer disposed on the rear surface of the coating layer, where the coating layer includes inorganic particles, an acrylate resin and an epoxy resin.
