The Techno Braces (テクノブレス Tekuno Buresu) were given to the team by Peebo, with which they use to transform and communicate. The transformation occurrs within five giant Bio Particles by which their powers activate and their suit forms around. When the red button on the right side of the Techno Brace is pressed, a monitor screen with the communication function opens upwards.
The Techno Brace reacts with the Bio Particles within the bodies of those who possess them, genetically engrained within the descendants of the five ancestors of the Biomen after Bio Robo granted it to them 500 years in the past. A Techno Brace cannot just be given to anyone and only those acknowledged by Bio Robo and Peebo can be granted the device.
At the climax of the Legend War, the Techno Braces were made redundant when the Biomen sacrificed their powers with the rest of the first 34 Super Sentai to destroy the invasion force of the Space Empire Zangyack. Resurfacing as Ranger Keys, the Bioman powers would be used by the Gokaigers to assume their forms via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.
