An intellectual refrigerator combining with a portable electric device is present. The viscoelastic properties of osteons include, for example, mechanical properties and osteon content of various components such as collagen, mucopolysacharides, hydroxyapatite, osteocytes and osteoblasts. The substrate may be a cloth sheet, a synthetic resin sheet, or the like. The device includes a linear actuator driven by an electric motor coupled to the actuator through a gearbox and a rotatable shaft.
