ElecSil™: Conductive Silicone Dry Electrodes for Wearable EMG, ECG, and EEG

ElecSil™ is a conductive silicone-based dry electrode material designed for long-term bio-signal sensing on the skin. It was developed to overcome the limitations of gel-based and rigid metal electrodes in real-world wearable and medical applications.

Traditional wet electrodes depend on conductive gel and adhesives, which can dry out, irritate the skin, and degrade signal quality over time. ElecSil™ instead maintains direct, conformable contact with the skin without gels or frequent replacement, making it suitable for continuous monitoring and repeated use.

How ElecSil™ Works on the Skin

ElecSil™ is engineered as a soft, conformable electrode that minimizes skin–electrode impedance through mechanical conformity rather than moisture. When placed on the skin, the material deforms with the body and follows micro-level skin irregularities, improving contact area and stability.

Human skin is not a flat surface. It consists of continuously changing curvatures, micro-irregularities, and dynamic deformations caused by movement, muscle contraction, and posture changes.

ElecSil™ electrodes are engineered with an ultra-thin, flexible structure that naturally conforms to these complex skin geometries. As the body moves, the electrode follows the skin’s curvature and deformation instead of detaching or concentrating pressure at specific points.

This conformability minimizes localized contact loss that commonly occurs with rigid or semi-rigid electrodes. As a result, the electrode–skin interface remains spatially and temporally uniform during wear, reducing fluctuations in skin–electrode impedance over time and across the contact area.

By maintaining stable, continuous contact even under motion, ElecSil™ enables more reliable and repeatable bio-signal acquisition compared to conventional electrodes that rely on flat, moisture-dependent contact mechanisms.

Because ElecSil™ maintains uniform contact pressure during daily movement and perspiration, it reduces motion artifacts and impedance drift that commonly occur with drying gels. This mechanical compliance enables stable acquisition of EMG, ECG, EEG, and skin impedance signals, even during extended wear or dynamic activity.

Why Dry Electrodes Matter for Wearables

Most legacy electrodes were originally designed for short clinical sessions rather than continuous, everyday use. For wearable systems, this leads to recurring consumable costs, complex preparation steps, and user discomfort.

Dry electrodes like ElecSil™ address these issues by enabling reusable electrode structures that can be washed and integrated directly into garments and soft devices. This simplifies maintenance, reduces waste, and makes it easier to scale bio-signal sensing into consumer products and digital health platforms.

Typical Applications of ElecSil™

ElecSil™ is used as a material platform for integrating bio-signal electrodes into textiles, wearable devices, and human–machine interfaces. It can be patterned as thin, flexible electrodes for smart garments that capture EMG and motion-related signals during sports, rehabilitation, or everyday activities.

In rehabilitation and physical therapy systems, ElecSil™ supports long-term EMG and ECG monitoring without the need to repeatedly attach and remove disposable gel pads. It is also suited for research-grade bio-signal measurement setups where stable, repeatable contact is critical for EMG, ECG, and EEG experiments.

Customization and Integration

ElecSil™ can be produced in customized sizes, thicknesses, and geometries to match different electrode layouts and device designs. It is compatible with various connector and wiring schemes, making it straightforward to integrate into existing electronics and wearable form factors.

Because ElecSil™ is based on a silicone platform, it can be co-designed with other stretchable or textile layers, such as compression fabrics, straps, or VR/EMS suits. This allows developers to prototype and scale products using the same underlying electrode material.

ElecSil™ as a Material Platform

ElecSil™ functions as a material platform for designing conformable, conductive interfaces between electronics and the human body. As demand grows for comfortable, long-term bio-signal monitoring in health, sports, and immersive systems, such dry electrode materials are becoming foundational components of next-generation wearables.

By combining mechanical flexibility, washability, and stable electrical performance, ElecSil™ helps bridge the gap between rigid electronics and soft, curved human surfaces. This makes it a suitable basis for future products in smartwear, medical devices, and human–machine interaction.
