SUNMAS Introduces SM9189 and SM9203

SUNMAS recently presented updates to two important products: SM9189 and SM9203.

SM9189 is a mature, forehead-worn neurostimulation product developed for migraine-related applications. It has been refined through continued development, customer feedback, and repeat orders from long-term customers. Its FDA 510(k) submission process is also moving forward.

SM9203 represents a different kind of progress. It is the first SUNMAS product to integrate low- and medium-frequency electrical stimulation, heat, and red light into one wireless wearable platform.

Together, these two products expand SUNMAS’s capabilities in targeted neurostimulation, multifunctional electrical stimulation, and customized OEM/ODM development.

SM9189: A Mature Product Developed for Migraine Applications

SM9189 is one of the most established products in SUNMAS’s tDCS and targeted neurostimulation portfolio.

Its specific technical approach is based on transcutaneous trigeminal nerve stimulation, also known as e-TNS. The product was developed around the needs of users seeking a wearable and easy-to-operate option for migraine-related applications.

SM9189 uses a compact magnetic controller attached to a specially shaped forehead electrode. Its lightweight design helps improve comfort during use.

A single button controls the main device functions, while two preset stimulation programs support different usage scenarios.

The product can also connect to the DOMAS app. DOMAS is a sub-brand of SUNMAS focused on connected devices and digital user experiences.

Through the DOMAS app, users can control the device, adjust the stimulation level, review session records, maintain a user diary, and view data summaries.

SM9189 is no longer an early-stage product concept. Several long-term SUNMAS customers have already placed orders, and their practical feedback has helped us improve the structure, controls, accessories, and overall user experience.

The FDA 510(k) submission process for SM9189 is currently underway. Our team is actively advancing device verification, technical documentation, and regulatory work as part of the review process.

Product claims, intended use, and market availability will follow the applicable regulatory requirements in each country or region.

SM9203: Three Technologies in One Wearable Platform

SM9203 is an important step forward for the SUNMAS product portfolio.

For the first time, we have integrated three technologies into one wireless wearable product:

• Low- and medium-frequency electrical stimulation
• Adjustable heat
• Red-light functionality

Many wearable products in this category provide electrical stimulation alone or combine electrical stimulation with heat.

By adding red light to the same platform, SM9203 offers a more versatile product concept and creates clear differentiation within the category.

This development involved much more than placing three functions inside one housing.

Electrical stimulation, heat, and red light each require different control systems, output management, structural design, and safety considerations. Bringing them into one stable platform required our R&D team to work across waveform development, temperature control, optical components, electronics, mechanical design, app connectivity, skin contact, and overall device safety.

SUNMAS has more than 30 R&D engineers working across electronics, software, structural design, electrical stimulation technology, and product applications. Their combined experience made this product development possible.

Practical Features With Clear Controls

SM9203 currently provides:

• Six electrical stimulation programs
• Twenty stimulation intensity levels
• Three heat settings from 38°C to 42°C
• Three red-light settings
• Adjustable operating time from 1 to 60 minutes
• Control through the DOMAS app

The product can be secured with a wearable strap and used on areas such as the shoulders, lower back, elbows, wrists, knees, and limbs.

Through the DOMAS app, users can select stimulation programs, adjust intensity, control heat and red-light settings, and set the desired operating time.

The red-light function is controlled independently from the electrical stimulation and heat functions. This gives users access to multiple technologies while keeping the operating process clear.

SM9203 is more than a new product model. It marks an expansion of SUNMAS’s R&D capabilities—from established electrical stimulation and heating technologies to a product platform that also incorporates optical functionality.

Two Products, Two Development Paths

SM9189 and SM9203 reflect two different approaches to product development.

SM9189 starts with a clearly defined application. It has become more mature through continued engineering work, customer orders, and practical feedback.

SM9203 starts with technologies that SUNMAS already understands well and combines them in a new way. It is our first product to bring electrical stimulation, heat, and red light together in one wearable platform.

One product emphasizes focus and maturity. The other emphasizes integration and innovation.

Both follow the same principle: every function must serve a real purpose, every technical decision must be evaluated, and every design must be suitable for stable production.

We are not interested in adding features simply to make a product appear new. We focus on whether the product is practical, understandable, reliable, and suitable for the customer’s target market.

More Options for OEM and ODM Development

SM9189 and SM9203 also create new opportunities for OEM and ODM cooperation.

Depending on technical feasibility and target-market requirements, customization options may include:

• Product appearance and colors
• Electrical stimulation programs
• Intensity and heat settings
• Red-light configurations
• Electrodes, straps, and accessories
• DOMAS app interface
• Packaging and user instructions
• Private-label branding
• Technical and regulatory documentation

If you are planning a migraine-focused neurostimulation product or a wearable device that combines electrical stimulation, heat, and red light, talk with SUNMAS about your product concept and target market.

Our product, engineering, and regulatory teams will work with you to evaluate a practical development path.
