Electrostatic attractor and robot hand comprising same

Abstract

To provide an electrostatic attractor having excellent durability and capable of achieving more reliable attraction and gripping of an object to be attracted with electrostatic force. An electrostatic attractor includes a laminate sheet formed by sequentially laminating at least a first soft polymeric organic substance, an electrode, and a second soft polymeric organic substance, and a power source device configured to apply voltage to the electrode, electrostatic force generated by applying voltage to the electrode being used to attract and grasp an object to be attracted, with one of the soft polymeric organic substances as a contact surface, in which the first soft polymeric organic substance and/or the second soft polymeric organic substance have tensile modulus of 1 MPa or more and less than 100 MPa, and volume resistivity of 1×108 to 1013 Ω·cm, and the electrode is a fiber component subjected to electroconductive treatment. A robot hand includes the electrostatic attractor.
