Muscle Suit

The Muscle Suit by Innophys is a powered back support exoskeleton for lifting.  The power is generated using air muscles at the back that cause a rotation around the hips.

In 2016 over 85 units of the Muscle Suit have been produced and are being tested in Japan.


The Muscle Suit is the creation of Innophys and it is part of a broad effort in East Asia to create wearable devices to assist the workers of an aging population.

The Muscle Suit is a powered hip exoskeleton for lifting (pick and carry).  It uses compressed air that is stored in a high-pressure cylinder attached to the back.  Alternatively, the suit can be connected to a compressed air hose, commonly found in many worksites.  It can also be powered using a portable compressor, but they can be loud.

Controlling the Muscle Suit can be done in one of two rather unique ways.  The user can either touch a control surface using their chin or blow into a tube.  This creates a hands-free control system for a powered exoskeleton.

The muscle suit is wrapped inside a custom, water repellent bag.  This protects the device from the elements and gives it a softer appearance.

There are three different versions of the Muscle Suit depending on the amount of power that is needed for the application.  The device weighs anywhere from 4.5 to 5.5 kg (10 to 12lb).
