LigaSys develops Smart Ligament™ systems—reactive, garment-integrated wearable hardware that detects unsafe joint motion and mechanically engages in real time to protect athletes. Unlike passive braces or tape, these systems stay transparent during normal movement and only activate during dangerous motion, addressing injuries that occur faster than the nervous system can respond. The platform is designed to be adaptable across joints, with the ankle as its first proof point.

Problem
Ankle inversion injuries can occur in as little as 40 milliseconds—faster than the peroneal reflex can mount a protective response. Existing solutions like braces, tape, and compression wear provide passive, always-on support that restricts normal movement, while sensing wearables collect data but cannot physically intervene. This leaves a critical window between when a roll happens and when protection engages, contributing to up to 80% reinjury rates in high-risk sports.
Solution
LigaSys builds Smart Ligament™ systems—reactive, garment-integrated wearable hardware that detects dangerous joint motion in real time and mechanically engages to protect the joint during the injury event. The systems stay completely out of the athlete's way during normal movement, then activate instantly when unsafe motion is detected, functioning like a seatbelt for the joint. The underlying architecture—sensing, deciding in real time, and mechanically intervening—is designed to be adaptable across joints, sports, and form factors, with the ankle as the first implementation. The company applies medical-device design discipline to the performance wearable context, working with athletes, coaches, and sports medicine professionals to refine the technology.
Target Audience
Primary customers are sports teams, athletic organizations, and performance-focused entities seeking to reduce injury frequency and severity, as well as sports equipment and apparel brands interested in building on the reactive joint protection platform.
Features
- Reactive wearable hardware that mechanically engages within the injury window (40-80 ms) rather than merely collecting data
- Garment-integrated design that requires no reapplication and remains transparent to the athlete during normal play
- Real-time motion sensing and decision-making architecture adaptable across multiple joints beyond the ankle
- Engineered to medical-device standards with rigorous, testable design methodology applied to performance wearables
- Differentiated from braces and tape by not restricting normal movement while still responding during injury events
