Bio-Sensor is a Quasi-Psycommu device developed by Anaheim Electronics. Although its full capabilities are unknown, its primary purpose is to allow a Newtype pilot to more easily interface with his mobile suit via mental commands. The bio-sensor could also have a rather surprising side effect when the pilot is mentally and emotionally focused enough (usually when angry or upset) to cause the bio-sensor to amplify the power, speed, and strength of the mobile suit for a short period of time.

Finally, the Zeta Gundam was equipped with the Bio-Sensor, a Quasi-Psycommu device that assisted with the mobile suit's controls using the pilot's brainwaves, improving its responsiveness. Though details about this device was unclear, there were instances of it allowing the Zeta Gundam to demonstrate abilities beyond its specifications during combat. Overall, the Zeta Gundam had exceptionally high operability and was regarded as a masterpiece of the Gryps Conflict era.
