Knee Brace

A method of providing support to a knee of a user, the method comprising:

• wearing a flexible sleeve around the knee, in which the flexible sleeve comprises a flexible fabric;
• detecting, using a first sensor, a bending of the flexible sleeve;
• and
• using a controller to control a sleeve tightness adjustment mechanism to adjust a tightness of the flexible sleeve around the knee based on an output signal of the first sensor.

A system comprising:

• a knee brace comprising:
• a flexible sleeve that comprises a flexible fabric;
• a memory device configured to store a reference bending angle of the flexible sleeve and a first threshold angle value;
• a first sensor configured to measure a bending angle of the flexible sleeve;
• a sleeve tightness adjustment mechanism configured to adjust a tightness of the flexible sleeve;
• and
• a controller configured to receive a first measurement signal from the first sensor, compare a first measured bending angle of the flexible sleeve with the reference bending angle of the flexible sleeve, and control the sleeve tightness adjustment mechanism to increase a tightness of the flexible sleeve in response to determining that the measured bending angle is larger than the reference bending angle by an amount greater than the first threshold angle.
