Research

Research in rehabilitation robotics, SMA actuation, clinical robotics, and biomedical engineering.

Research

From physical mechanism to validated robotic system

My research explores how compact actuation, sensing, and control can be integrated into robotic systems for healthcare. The current focus is rehabilitation robotics with Shape Memory Alloy actuators; earlier work spans clinical robotics, 3D ultrasound, and biomedical signal processing.

Rehabilitation robotics

Devices for controlled early-stage mobilization, designed around human anatomy, repeatable motion, and safety-oriented operation.

Smart and soft actuation

Antagonistic SMA mechanisms, tendon transmission, indirect thermal supervision, and embedded state-based control.

Experimental validation

Tracking performance, repeatability, endurance, thermal behavior, and transparent reporting across progressively demanding tests.

Current research question

How can a compact SMA-driven ankle module deliver controlled, repetitive movement while respecting the thermal and recovery constraints of its artificial muscles?

The research treats this as a system-level problem. Mechanical pretension, tendon routing, actuation logic, sensing, controller design, and recovery states all influence the final motion.

Research context

The current work is conducted at RoboticsLab, Universidad Carlos III de Madrid, as part of Soft Robotics for Ankle Rehabilitation (SRAR), grant PID2023-149141OB-I00. I contribute to this research as Scientific and Technical Activities Staff while developing my master’s thesis.
