In the world of medical technology, advances are redefining healthcare and improving patients’ quality of life.
Two crucial areas in this field are control systems and actuators, essential elements in the production of medical devices such as prostheses and diagnostic equipment.
In this article, we will explore how these technological innovations are transforming the way we address medical challenges.
Modern prostheses are not simply mechanical replacements, but technological extensions that integrate intelligently with the human body. Electric actuators play a crucial role in providing precise and controlled movements These actuators are connected to control systems, which act as the bridge between the prothesis and the user.
Control systems are capable of interpreting the user’s signals, captured by sensors such as electromyograms (EMG), to translate them into specific movements of the prosthesis. This level of customization allows users to modulate the strength, speed and position of the prosthesis, adapting it to different daily tasks and activities. Thus, technology not only restores functions, but also enhances the autonomy and quality of life of those who use it.
Devices such as the Hand of Hope (HOH) stand out for their innovative approach, focused on leveraging technological advances to create not just a rehabilitation tool but a comprehensive solution incorporating devices such as linear actuators
An outstanding feature that drives the efficiency of the HOH is the presence of REGNER linear actuators They play a crucial role in facilitating precise movements tailored to the individual needs of the patients.
The hand is placed on the back of the damaged hand, with two surface sensors attached to the extensor and flexor muscles of the arm, to detect surface electromyographic (EMG) signals for active participation during exercise.
The EMG signals are processed so that the patient can see the movement of the muscle, where the EMG electrodes are positioned, it should be noted that there is no electrical current applied to the patient.
The HOH therapy device is intended for use in patients who need hand or forearm rehabilitationmaking it easier for them to begin to contract the muscle voluntarily, to have motor control and coordination, it also helps them with muscle relaxation, to have motivation to improve, control of abnormal muscle activity and have continuous reinforcement of correct responses
As medical technology advances, the integration of linear actuators into devices such as the Hand of Hope continues to evolve, the ability of these actuators to provide controlled movements tailored to the specific needs of patients underscores the importance of customization in the rehabilitation process.
In this case, REGNER contributed his expertise in control systems, integrating his RA-MINI ALU, a perfect combination between power and ultra compact design. The RA-MINI ALU is perfect for those applications, such as HOH, where tilt, lift, retract and thrust forces are required, in a very limited space.
The customization fo our control systems is very important to us, considering that technological innovation is a priority in REGNER, where we listen and understand the projects of each client, motivating us to innovate and contribute to the development of technological advances.
On 26–27 August 2026, REGNER’s engineering team visited All About Automation Zürich, held alongside maintenance Schweiz at Messe Zürich, to take stock of the latest trends in motion control, collaborative robotics and mechatronics — and to compare them against REGNER’s own developments in diagnostic-ready linear actuators.
Choosing a microactuator for analytical instrumentation takes more than force, speed and stroke. These are the seven technical questions an OEM engineer should answer before deciding, drawn from REGNER’s experience with instrumentation manufacturers.
Oriol Garay, a Materials Engineering student at the UPC, has joined REGNER to work on an applied tribology project focused on the interface between the lead screw and the nut. The project will examine how surface treatments and finishes affect friction, wear and the functional repeatability of microactuators.
Expoquimia and Equiplast 2026 confirmed that water management has become a strategic priority for the process industries. This evolution calls for more compact, automated and reliable systems to monitor, dose and control fluids precisely in analytical instrumentation and treatment equipment.
