Fans have made their own working Wolverine-inspired claws before, but Advancer Technologies recently revealed an impressive set of bionic claws that react to your flexing muscles. Even better: You can make your own with their tutorial.

The bionic claws extend and retract with the help of Advancer Technologies’ MyoWare fourth-generation muscle sensor. As the video shared on the company’s YouTube channel demonstrates, it will sense when you flex and relax your forearm causing the claws to react. If you keep your muscle flexed, you can lock the claws so they stay extended.

With the help of 3D printing, you can make these Wolverine claws for yourself. The instructions are available on However, to get the MyoWare part, you’ll have to check out Advancer Technologies’ current Kickstarter campaign for the sensor.

These claws are the last of two tutorials the company said it would release during the Kickstarter. The first tutorial featured an Iron Man bionic repulsor glove that also uses the MyoWare sensor and fires depending on your flexing muscle. The steps for making the glove are available on Instructables.

The MyoWare campaign has exceeded its initial fundraising goal and raised more than $17,000. For every five backers at the $25 level or higher, the Kickstarter will also donate a sensor to the non-profit Limbitless Solutions. Limbitless created the bionic arm that Robert Downey Jr. presented to a young fan in March. As of Thursday, there are still seven days left to the campaign.
