• Stage — Working prototype · Seeking clinical partners and investment
• Hardware — Surface EMG sensor (OYMotion), dry electrodes, microcontroller, Wi-Fi, display
• Software — Web app for training management, real-time monitoring, remote progress tracking
• Origin — Hebron IT Academy students + HebronSoft engineers · Started with a 3D-printed bionic hand
• 2026 — First veteran cohort in Lviv · New student cohort in Kyiv · Building together

Re-Band began as part of HebronSoft’s work on affordable bionic prosthetics, developed together with students from Hebron IT Academy in Lviv. After the full-scale invasion, the need for accessible prosthetic solutions became urgent. The team built HebronCare 1.0 — a 3D-printed hand using Arduino and EMG electrodes, providing an affordable solution for people in Ukraine waiting for full prosthetic fitting.

The team also built a custom Ignition dashboard to track muscle sensor activity in near real time — giving users live feedback on how the prosthesis responded to their muscle signals and creating a measurable training environment that addressed both physical and psychological readiness.

HebronCare 1.0 was recognized with the Inductive Automation 2025 Educational Engagement Firebrand Award — acknowledging the project as an example of how industrial technology and engineering education can come together around a real human need.

Working on that project brought the team into direct conversations with rehabilitation specialists. What they heard consistently pointed in a different direction.

Around 65 million people worldwide live with limb amputations, with approximately 1.5 million new amputations performed every year. Diabetes and vascular disease remain the leading causes globally, while the war in Ukraine has created tens of thousands of additional cases and accelerated the need for accessible rehabilitation technologies. About two-thirds of people living with limb loss are in low- and middle-income countries, where access to prosthetics and rehabilitation is most limited.

After an amputation, waiting for a prosthesis can take weeks or months. During that time, residual muscles lose tone and responsiveness. By the time the prosthesis arrives, many patients have already lost the muscle control they need to use it.

The wait also affects motivation and confidence. Some patients adapt to life without a limb and stop engaging with rehabilitation altogether. Many existing approaches require specialized equipment or continuous clinical supervision — which limits access to consistent training outside the clinic.

What Clinicians Kept Saying

The feedback from doctors and rehabilitation specialists was consistent: the period before a person receives a prosthesis is often just as critical as rehabilitation afterward. Patients were losing muscle activity and motivation during the wait, and arriving at prosthetic fitting less prepared than they could have been.

Re-Band addresses what happens before the prosthesis arrives — not after.

Why This Matters

Limb loss affects millions of people worldwide, yet most rehabilitation technologies focus on life after a prosthesis is fitted. Re-Band addresses an earlier stage of recovery: helping patients preserve muscle activity and engagement during the weeks and months before a prosthesis arrives.

The current prototype reads muscle signals, shows activity in real time, and sends data to a server where therapists can track progress.

Wearable EMG Monitoring

The device uses non-invasive surface EMG sensors to capture bioelectrical muscle signals through dry electrodes, allowing patients to train residual muscles without specialized clinical equipment.

Personalized Calibration

The system sets individual activation thresholds based on each user’s own muscle signals — measuring both rest and active contraction. These thresholds are used during training to show whether the patient has reached the target level of activation and how consistently they can hold it.

Real-Time Feedback and Remote Monitoring

Muscle activity is displayed on the device in real time and transmitted to a server. Rehabilitation specialists can review training data remotely and track how a patient’s muscle function changes over time.

Interactive Training

The long-term vision includes game-based and interactive experiences that help patients stay motivated and engaged throughout the rehabilitation process.

Re-Band is being developed inside HebronSoft’s Innovation Lab. This year, veterans from the first Hebron IT Academy cohort in Lviv joined the project — contributing their own experience with rehabilitation and helping shape future development. A new student cohort beginning in Kyiv will work alongside HebronSoft engineers on the next generation of the device.

Some of the people building Re-Band are also the people it was designed to help. Their experience shapes the product from the very beginning.

Re-Band is a working prototype at an early stage. The next phase focuses on clinical validation, user testing with rehabilitation specialists, and refining the device based on real patient feedback.

We are looking for clinical partners who can test the device with patients, and for investors who see affordable rehabilitation technology as a gap worth closing.

If you work in rehabilitation medicine, prosthetics, or HealthTech investing, we’d love to explore what Re-Band could become together.
