βIn wireless charging, aspects related to electrical and electronic engineeringβsuch as circuit configuration and power efficiencyβare effectively at a completed stage; to improve performance further, we need to look elsewhere. In particular, materials have been an area largely overlooked by existing industry experts and could provide a new answer. Eta Electronics aims to replace conventional ferrite materials with Space&Beanβs Scutum Sβa shielding material that protects equipment from radiation, electromagnetic interference, and other factorsβto raise overall completeness by another level.β
Yeo Tae-dong, Co-CEO of Eta Electronics, sees future market potential in the adoption of new materials and in collaborative relationships. After earning a Ph.D. in wireless power transfer from the School of Electrical Engineering at KAIST, he co-founded Eta Electronics in 2019 with Co-CEO Nam Jeong-yong. Within one year of its founding, Eta Electronics was selected for the Ministry of SMEs and Startupsβ TIPS R&D program; in its second year, it was selected for an R&D program by the Ministry of Science and ICT; and in its third year, it was named to the βSuper-Gap Startup (DIPS) 1000+β program, underscoring its technological prowess.
Most recently, the company became the first in Korea to obtain KC certification for a wireless charging device, marking rapid progress toward industrial standardization and commercialization. This year, through a cooperative framework with a materials engineering company, its goal is to push the upper limits of wireless charging technology. We spoke with Eta Electronics Co-CEO Yeo Tae-dong and Space&Bean CEO Min Kyung-ryeong to hear about the overall contours of their collaboration.
Making inroads into the wireless charging device market with the βELYXβ solution
Eta Electronics offers the magnetic resonanceβbased wireless charging solution βELYXβ and βELYX LINK,β a service that enables real-time wireless power monitoring and remote control, as well as power data analytics and forecasting. The ELYX hardware comprises four modules: a transmitter (Tx) control module, a Tx coil module, a receiver (Rx) control module, and an Rx coil module, which are installed respectively on the station and on devices requiring wireless charging. The current lineup includes the 150 W compact ELYX-150, the 550 W ELYX-10A, and the 2.4 kW ELYX-40A. From coils and antennas to circuits, firmware, and the data monitoring platform, all components are designed and manufactured in-house.

What sets ELYX apart is that it has obtained KC certification under Koreaβs national integrated certification system. Eta Electronics persuaded the Ministry of Science and ICT (MSIT), the National Radio Research Agency (RRA), and the Korea Radio Promotion Association (RAPA) to revise the existing KC certification framework for wireless charging. Responding to this, MSIT issued a notice in March easing βregulations on robotic wireless charging.β As a result, the certification scopeβpreviously limited to around 50 Wβnow extends up to 1 kW for commercial and industrial robots. KC certification attests to product safety and technical efficiency, enhancing product credibility both domestically and overseas.
The ELYX solution is already in use by multiple autonomous robot companies, including Neubility, AMR Labs, and Movin.
Wireless power transfer has peaked; materials must raise the ceiling
Building on KC certification and other milestones to bolster commercial viability, Eta Electronics is also pursuing improvements through materials engineering. βCurrent wireless charging technology is concentrated on electrical and electronic aspects. Circuit design and power efficiency are essentially complete,β said Co-CEO Yeo Tae-dong. βAccordingly, we began collaborating with Space&Bean on the premise that replacing conventional ferrite materials could further enhance performance.β

Eta Electronics plans to integrate Space&Beanβs Scutum S into its ELYX solution. βThe wireless charging system we are developing fundamentally transmits power via magnetic fields. It is therefore crucial to confine and shape those fields effectively, and this is where shielding materials can be applied. Higher-power charging requires thicker ferrite. By applying Scutum S across multiple shielding components, we can make the system thinner and lighter, achieving major advances in weight, volume, and usability,β said Co-CEO Yeo Tae-dong.

Commercial competitiveness will also be significantly strengthened. βSuppose a factory operates 100 robots. Charging them wirelessly requires space for 100 chargers, and today, due to bulk, wireless chargers are typically installed upright. If we use Scutum S to slim down the charger itself, we can embed chargers in the floor, saving space and enabling opportunistic top-up charging to increase uptime,β Yeo added. βBeyond improving energy efficiency, this greatly expands the practical utility of the wireless charger itself.β
Next-generation products to drive overseas expansion, with a focus on diversified material substitution
There are countless cases of collaboration between technology companies and materials firms. In the early 2010s, BMW partnered with Germanyβs carbon-materials specialist SGL Carbon to introduce carbon fiberβthen used mainly in supercarsβinto mass-market electric vehicles, opening the door to commercialization with the launch of the BMW i3. ASML, a manufacturer of semiconductor lithography equipment, achieved sub-7-nanometer processes not through innovations in ultraviolet light sources but by leveraging Carl Zeissβs lens technology. Building on this, ASML now enables circuits at 2 nm and below, supporting the global semiconductor market.

The partnership between wireless charging solution provider Eta Electronics and radiation-shielding materials company Space&Bean follows the same logic. In particular, CEO Min Kyung-ryeong expects the two firms to set and achieve even greater goals through their collaboration. βWhen applying new materials to industry, safety is paramount, followed by technological capability. Going forward, advanced industries will hinge on light-weighting and technological sophistication, and it is difficult for a startup to accomplish such tasks alone. With that in mind, we joined hands with Eta Electronics to achieve our shared objectives,β said Min.
Min continued, βThrough Eta Electronics, Space&Bean has confirmed the potential to enter new markets and to take on a range of industries that need material substitution. We are already receiving collaboration requests in many fields and are approaching them from multiple angles. Deep tech means digging deep into technology, but it also means approaching it multidimensionally. We will build the Scutum S brand so that it pioneers industry at large, including space, and we will work to establish it as a market standard.β
Co-CEO Yeo Tae-dong added, βAdvances in magnetic materials will elevate wireless power transfer technology to the next level. Our engagement with Space&Bean is expected to further enhance the value of the ELYX brand, and our long-term goal is to establish it as a standard in the wireless charging market.β
