A sensor web is a garment of finely woven sonar units, typically utilized by the blind during the 23rd century to help carry out normal lives. The web can be worn naturally over everyday clothing. It emits low-level sonar scans undetectable to the human senses (presumably ultrasonic), and translates return signals into media perceptible by the trained wearer.

The blind Dr. Miranda Jones was one user of a sensor web in 2268. She stated to Captain James T. Kirk that she could "play tennis" with him while wearing the web. (TOS: "Is There in Truth No Beauty?")

Sensor webs were replaced by VISORs, cybernetic ocular implants, cloned visual organs or neural regeneration techniques in the 24th century.
