Tactile sensor and android
A tactile sensor has an elastically deformable sheet, a coil that is provided in the sheet, a powdery or fibrous magnetic material that is provided in the sheet with the coil, and a detection portion that detects an inductance of the coil. The coil is wound in a spiral shape and the powdery or fibrous magnetic material is dispersed in the sheet.
1. A tactile sensor comprising:
an elastically deformable sheet;
a coil that is provided in the sheet;
a plurality of fibrous magnetic material that is dispersed in the sheet in a manner so as to directly contact the coil; and
a detection portion that detects an inductance of the coil, wherein:
the coil is wound in a spiral shape,
the plurality of fibrous magnetic materials are provided in the spiral shape of the coil,
the fibrous magnetic material includes a plurality of strands inserted at a center of the coil,
the coil includes a plurality of coils, and the plurality of coils are arrange in a mesh form, and
a spacing between adjacent ones of the plurality of oils is relatively wide so as to effectively increase the inductance of the coil.
2. The tactile sensor according to claim 1 , wherein a blending amount of the fibrous magnetic material is equal to or more than 2 phr and is equal to or less than 10 phr.
