Innovating the Future: Boston University Engineering Students Revolutionize Mobility Devices

October 16, 2025

cambridge, MA – two Harvard University students are poised to disrupt the treatment of foot drop with Sole1, an innovative robotic sock designed to restore mobility and, crucially, improve the emotional wellbeing of patients. Bradley Wagman and Viktor Bokisch, the co-founders of the venture, have engineered a device that moves beyond conventional, frequently enough stigmatizing, braces.

Addressing a Widespread Condition

Foot drop, characterized by the weakening or paralysis of muscles responsible for lifting the front of the foot, affects millions globally. Statistics from the Fort Worth Brain & Spine institute indicate that approximately 17 percent of the U.S. population has encountered the condition or knows someone who has. Existing treatments, typically rigid braces, often carry a significant psychological burden for users.

Sole1: A Modern Solution

Sole1 deviates from conventional approaches with its smart sock design. The system comprises an ankle bracelet equipped with a computer and a specialized sock containing filaments. Precise algorithms measure the foot’s angle and, upon detecting a drop, deliver targeted electrical signals to correct the motion. This proactive approach aims to prevent the foot from dragging and restore a natural gait.

Beyond Functionality: Prioritizing Patient Wellbeing

Wagman and bokisch emphasized that their innovation focuses equally on the psychological impact of mobility devices. Interviews with over 40 therapists and patients revealed that current braces are frequently enough perceived as dehumanizing and can hinder confidence. One patient even expressed reluctance to wear a brace that clashed with his preferred footwear. This insight drove the duo to create a device that is both effective and aesthetically considerate.

“We are focused on creating something that increases people’s physical and mental confidence,” Wagman explained. “Whoever you’re designing a device for, you have to think about their entire surroundings.”

From Military Service to Innovation

The journey to Sole1 is deeply rooted in the founders’ personal experiences. Both Wagman and Bokisch served in the military,where they encountered the challenges faced by individuals with mobility limitations. Bokisch’s experience working alongside a service member with a prosthetic leg highlighted the importance of dignity and self-esteem. Wagman, previously an industrial design student and tattoo artist, brought a unique perspective on aesthetics and user experience.

Their paths converged at Harvard, where a robotics course sparked their collaboration. Inspired by a guest lecture on existing foot drop treatments, they began developing their own solution. The project gained momentum, culminating in winning the prestigious James Dyson Award in September 2025.

Looking Ahead

With the initial technical hurdles cleared, Sole1 is now focused on navigating the complexities of startup logistics and regulatory approvals. Wagman envisions integrating machine learning to personalize the device’s response further. The long-term goal is to extend their soft robotic textile technology to address a wider range of mobility impairments.

Understanding Foot Drop: A Deeper Dive

Foot drop can stem from a variety of underlying causes, including stroke, nerve injuries, muscular dystrophy, and cerebral palsy. Early diagnosis and intervention are crucial for managing the condition and preventing long-term complications. Current research explores various therapeutic approaches, including physical therapy, orthotics, and functional electrical stimulation-the principle behind Sole1. According to the National Institute of Neurological Disorders and Stroke,approximately 1.5 to 2 million Americans are affected by stroke each year,with a significant percentage experiencing foot drop as a result.

How might advancements in biocompatible materials impact the long-term viability and acceptance of implanted neural interfaces for prosthetic control?

Advanced prosthetics & Bionic Limbs: BU’s Cutting-Edge Research

Boston University’s College of Engineering is rapidly becoming a hub for innovation in mobility devices, particularly in the realm of prosthetics and assistive technology. Students and faculty are pushing boundaries, developing solutions that go beyond simply replacing lost function – they’re aiming to enhance it. This work spans multiple disciplines, including biomedical engineering, mechanical engineering, and electrical engineering, fostering a collaborative habitat crucial for complex projects.

Neural Interfaces & Myoelectric Control

A important area of focus is improving the control systems for prosthetic limbs. Traditional prosthetics often rely on simple on/off switches or limited pre-programmed movements.BU researchers are pioneering neural interfaces and advanced myoelectric control systems.

* myoelectric control uses sensors to detect electrical signals generated by muscles in the residual limb, translating these signals into movements of the prosthetic. BU’s advancements focus on:

* More sophisticated algorithms for signal processing, leading to more intuitive and precise control.

* Developing sensors that are less susceptible to noise and interference.

* Creating lightweight and pleasant sensor arrays that can be worn for extended periods.

* Neural interfaces, a more ambitious approach, involve directly connecting the prosthetic to the nervous system. While still in early stages, research at BU explores the potential of using implanted electrodes to restore a greater range of motion and sensory feedback. This includes work on osseointegration, where the prosthetic is directly attached to the bone, improving stability and reducing discomfort.

Powered exoskeletons: Restoring and Augmenting Mobility

Beyond prosthetics, BU engineering students are actively involved in the development of powered exoskeletons.These wearable robotic devices are designed to assist individuals with mobility impairments,or to augment the strength and endurance of able-bodied users.
