In September of 2021, after five years of research and development, Biomotum is ready to transition to a commercialization stage for its first product, the Biomotum SPARK robotic exoskeleton. The Biomotum SPARK is an active ankle exoskeleton for walking assistance. The company has its roots in helping children and young adults with cerebral palsy. In 2021, it was an experimental device only being used in research settings and was not yet cleared by the FDA.
The Biomotum SPARK is a powered ankle medical exoskeleton. The controllers, motors, and batteries are housed in a pouch pack around the waist (this saves the user from having to accelerate and decelerate these components with each step). The brushless DC motors are linked to the ankle exoskeleton using drive cables and provide plantar flexion and dorsiflexion torque to the body while adding minimal mass to the lower limb. The exoskeleton is made out of carbon fiber components and is powered by a single rechargeable lithium-ion battery. The Biomotum SPARK comes equipped with torque and angle sensors that feed into the controller. The control interface is available for both smartphones and tablets and can remotely control the device, set up user profiles, and track all usage.
In September of 2021, the SPARK Research System became available to clinical and biomechanical investigators as a research tool to carry out clinical trials. “We’re excited to provide our untethered, go-anywhere system to researchers conducting basic human mobility studies as well as those exploring more translational clinical questions,” said Dr. Zach Lerner, the CTO, and Co-Founder of Biomotum, adding that “the lightweight, ease of use, and broad utility of the SPARK make it a great tool for a wide range of applications when studying human mobility.”
“We continue to seek partners who can help fulfill our mission of optimizing human mobility by providing intelligent and intuitive wearable systems to individuals with CP, stroke, and other conditions that impair neuromotor performance and mobility,” said CEO, Ray Browning.

Exoskeleton Report does not endorse one exoskeleton product over another. The exoskeleton catalog is purely for educational purposes. The catalog is meant to provide an easily accessible birds-eye view of the exoskeleton industry, and a quick method to sort exoskeletons by type and purpose. All prices are approximate and are meant to provide a general sense of the cost of the devices.
