Elecsyor

POWERING SOFT MOTION

The company

Elecsyor is a young deeptech company originating from academic research, specializing in the development of fibrillar electrostatic actuators designed for soft and wearable robotics.

Its ambition is to make robotics more human, lighter, and seamlessly integrated into everyday life by creating a new generation of compact, silent, and energy‑efficient artificial muscles.

Based in Lyon, Elecsyor builds on strong scientific expertise and a commitment to delivering reliable, high‑quality technological solutions.

The Origin of the Project

Elecsyor emerged from research conducted at the LMTS Laboratory of the École Polytechnique Fédérale de Lausanne (EPFL) between 2020 and 2026.

This work led to the development of a one‑of‑a‑kind electrostatic motor capable of replicating the mechanical properties of a human muscle in the form of a flexible fiber.

After several years of experimental development and the demonstration of unprecedented performance, the project took shape in France with the objective of transferring and industrializing this technology for applications in robotics and wearable systems.

Technology

The technology developed by Elecsyor is based on a fibrillar linear electrostatic motor. Each fiber consists of two coaxial helical electrodes whose electrostatic interactions generate a reversible and continuous linear motion.

This motor combines compactness, flexibility, responsiveness, and modularity, while being integrable into textiles or flexible structures. Thanks to its cylindrical format and self‑aligning capability, it introduces a new technological building block for creating efficient, reliable, and miniaturizable artificial muscles.

Applications

The fibrillar motors developed by Elecsyor open the door to numerous applications in the fields of soft and wearable robotics

Humanoid robots

The modularity and compactness simplify the mechanical architecture of the limbs. The flexibility and back‑drivability improve the robot’s compliance during contact, while the silent operation makes it suitable for environments shared with humans.

Exoskeletons

The flexibility and light weight of the actuators make them easy to integrate into wearable structures without hindering movement. Their low power consumption reduces battery size, and their back‑drivability enables safe interaction with the user, free from unwanted resistance.

Prosthetics

The low weight and compact volume make integration into constrained sockets easier. The back‑drivability enables precise, non‑rigid control, and the low power consumption reduces charging frequency, improving everyday usability.

Exploration robot

The mechanical robustness and the ability to be back‑driven allow the system to withstand unexpected interactions with the environment. The modularity supports the design of compact and adaptable robots, while the low power consumption extends autonomy in remote or isolated terrain.

Haptic gloves

The light weight and flexibility prevent the hand from being burdened or the fingers from being constrained. The back‑drivability enables precise force feedback without added stiffness, and the silent operation is essential for immersive interfaces.

The founder

Sylvain Schaller, founder and inventor of the motor, is an engineer and holds a PhD in microengineering. He conducted his research on fibrillar electrostatic motors within the LMTS at EPFL before creating Elecsyor to bring this technology to industry. His background combines scientific rigor with entrepreneurial vision, strengthened by experience in innovation and industrial consulting at EY.

Driven by the belief that robotics should draw inspiration from nature and adapt to humans, he now leads Elecsyor with a technological and ethical mindset, focused on quality and long‑term sustainability.
