Biomechatronics
Summary
Biomechatronics is an interdisciplinary field that integrates principles of biology, mechanics, electronics and control theory to design systems that interact with, support or replicate biological functions. By combining sensor technology, actuators and intelligent control algorithms with insights from biomechanics and physiology, researchers develop devices such as powered prostheses, wearable exoskeletons and haptic interfaces. The goal is to achieve seamless human–machine symbiosis, enabling restoration of impaired functions, augmentation of human capabilities and safe collaborative robotics. Recent advances in myoelectric control, brain–machine interfaces and biologically inspired design have expanded applications from clinical rehabilitation to industrial ergonomics and human–robot collaboration in manufacturing. The field draws on multidisciplinary methodologies, including multibody dynamics, finite element modelling, real-time control and hybrid biosignal processing, to create systems that respond adaptively to user intent and physiological feedback.

Biomechatronics publication trend
The graph below shows the total number of articles in biomechatronics across all publications each year (not limited to Nature Index journals).
Technical terms
Biomechatronics: The interdisciplinary integration of biological insights with mechanical, electronic and control systems to develop human–machine interfaces and assistive devices.
Exoskeleton: A wearable mechanical structure, often motorised, that supports, augments or restores human limb function by applying controlled forces to the body.
Electromyography (EMG): A technique for recording electrical activity generated by skeletal muscles, commonly used as a control input in prostheses and exoskeletons.
Sensor fusion: The algorithmic combination of multiple sensor signals (e.g. inertial, magnetic, force) to estimate system states such as orientation, position or interaction forces with reduced noise and drift.
Hybrid controller: A control architecture that integrates biosignals (such as EMG or EEG) with mechanical sensor feedback to achieve adaptive assistance or rehabilitation therapy.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
