ElecSil™ 건식 전극 vs. 실 & 젤 전극: EMG/EEG를 위한 기술 비교

웨어러블 바이오센싱을 위한 전극 기술이 중요한 이유

웨어러블 기술에서 근육의 근전도(EMG)와 뇌의 뇌파(EEG) 같은 신체의 전기 신호를 정확하게 측정하는 것은 핵심 과제입니다. 수십 년간 이를 위해 끈적이고 일회용인 젤 전극에 의존해 왔습니다. 효과적이지만, 지속적인 실제 모니터링에는 이상적이지 않습니다.

더 나은 해결책을 찾기 위한 연구는 전도성 실과 같은 혁신으로 이어졌습니다. 하지만 진정한 원활한 통합을 위해서는 새로운 접근법이 필요합니다. 여기서 Wave Company의 ElecSil™ 기술이 등장합니다. 전도성 실리콘 스마트 텍스타일로서 ElecSil™은 기존의 한계를 극복하도록 설계되었습니다.

ElecSil™ vs. Disposable Gel Electrodes

The most common method for clinical biosignal measurement uses disposable Ag/AgCl (silver/silver chloride) electrodes. These are considered the "gold standard" for signal quality due to a wet gel layer that creates a stable, low-impedance connection with the skin.

Disposable Electrodes Limitations:

- Gel is cold, sticky, and can dehydrate, degrading signal quality

- Adhesive often causes skin irritation, making long-term use uncomfortable

- Single-use nature creates significant waste and recurring costs

- Impractical for integration into everyday clothing

ElecSil™ Advantages:

- Eliminates gels and adhesives, avoiding skin irritation

- Ultra-thin (less than 1mm), flexible, and moves with the body

- Tested to endure over 100 wash cycles

- Enables true smart garment integration for continuous monitoring

ElecSil™ vs. Conductive Thread Electrodes

Early smart textiles attempted to solve the problem by weaving conductive threads into garments. While a major step forward, this method has its own technical challenges.

Conductive Thread Limitations:

- Fine conductive fibers degrade after repeated stretching and washing

- Electrical properties can be inconsistent

- Significant motion artifacts due to unstable contact

ElecSil™ Advantages:

- Superior resilience due to bulk material structure

- Elasticity maintains stable, conforming skin contact

- Highly resistant to corrosion from sweat

The Verdict: Enabling the Future of Wearables

By creating a stretchable, washable, durable, and biocompatible dry electrode system, ElecSil™ overcomes the core limitations of previous technologies. It provides high-quality signal measurement required for meaningful EMG and EEG analysis without compromising comfort or practicality.
