Abstract

A finger glove for use in gripping movements with one or more fingers of a human hand enclosed in the glove. The glove includes glove fingers and a palm. At least one glove finger is adapted to include on each side an artificial tendon that extends along an inside of the glove. A yoke is fitted in a tip of the at least one glove finger and intended to surround a tip of an enclosed finger. At each side of the glove finger artificial tendons are connected to the yoke. A system including the finger glove having a force detecting sensor is situated on the inside of the at least one glove finger and is adapted to detect a force between a finger enclosed in the glove finger and a contact surface applied to the finger. The artificial tendons for a glove finger are connected to at least one actuator and a control unit adapted to cause the at least one actuator to exert a pulling force on the artificial tendons of the glove finger based on a force detected in the force detecting sensor, whereby the finger enclosed in the glove finger is caused to bend.
