BINARY ENCODING OF SENSORS IN TEXTILE STRUCTURES

A system and method comprising binary coding in a textile structure can include a textile sensor configured to sense a property and having a yarn pattern. A binary code can be associated with the yarn pattern. When the textile sensor senses the property, the property alters relative positions of yarns in the yarn pattern, causing the associated binary code to change. A particular change in the binary code represents a defined value of the property. As a result, a second textile sensor having a second yarn pattern can be designed based on the unique binary codes of the first textile sensor measurements, such that the second textile sensor provides predictable responses to different property values.

Methods and apparatus for sensor or controller that includes knitted fabric

A sensor may include a knitted pocket and loose yarn that is inside a cavity of the pocket. In some cases, this loose yarn is neither woven, nor knit, nor otherwise part of a fabric. A resistive pressure sensor may include a knitted pocket and loose conductive yarn that is inside the pocket. Pressure applied to the pocket may compress the loose yarn, which may increase the number of electrical shorts between different parts of the loose yarn, which in turn may decrease the electrical resistance of the loose yarn. A capacitive sensor may include a knitted pocket and insulative loose yarn that is inside the pocket. A strain sensor may include knitted conductive pleats. Electrical shorts may occur in contact areas where neighboring pleats meet. As the strain sensor stretches, these contact areas may become smaller, causing the electrical resistance of the pleats as a group to increase.
