Hi, good afternoon. I am Sung Ho Wang, CEO of Nemesis. As everybody knows, the digital healthcare market is growing rapidly, but healthcare device manufacturers are facing various issues. So today I would like to propose the chip solution to clear the issues. And here is why digital healthcare device manufacturers are facing various technical issues such as short battery life, large form factor, and high energy cost. Global chip vendors do not provide a chip customization service. It's mainly because bio signal processing is very, very difficult. Bio signals are basically very noisy and unpredictable and are affected by various interferences such as motion artifacts and electromagnetic interferences. So we should understand not only circuit design but also the bio signal itself. It is very important for device makers to choose the ideal chip for their bio sensor project. We provide a bio signal processing chip that can cover brain signals, cardio signals, blood vessel signals, and signals from biomarkers. With our solution, we can achieve long battery life, a small form factor, and the lowest energy cost, plus we provide a chip customization service based on our customers' requirements.
This is our product roadmap. The electrochemical bio signal processing chip group is for vital sign monitoring and biomarker monitoring. The second group, tiny machine learning-based bio signal processing chips, is for high-end medical devices, and the multimodal bio signal processing chip is for wearable devices such as smartwatches, smart bands, and smart rings. This is our first chip. We just completed the best production of this chip. The part number is NMS 4110; it receives the signal from bio sensors and provides amplification, filtering, and converting analog signals to digital signals and calculates the number. That's what the chip is doing. This is the world's first bio signal processing AI chip. The part number is NMS 4150; it consists of not only an analog part but also a 32-bit MCU, embedded flash memory, and SRAM. All the circuit blocks are integrated on a single silicon die, and we plan to adopt processing in memory, which is AI memory, and a neural processing unit, which is AIMCU, step by step.
This allows the device to be attached to a comfortable part of the body, and then it can be attached to clothing instead of directly to the skin. This is because we have very high input impedance technology. The second reason is that it is available for small-scale devices. Our chip can cover variable signals, even though the output is voltage, current, capacitance, or resistance. One chip can cover all and it shows high accuracy regardless of movement. This is because we have the highest common mode rejection ratio technology, which is an analog circuit technology, and it guarantees long battery life. We have a special low-power analog circuit technology. We provide a tiny machine learning-based AI algorithm as well as low-power universal interface analog circuit technology. Our current sensing resolution is very, very high. We provide a one-chip solution, including a Bluetooth chip as one package, as well as we provide customization service for all those items, the global chip and the stone provider. We plan to release three products per year, one by one.
The application areas cover vital sign monitoring and biomarker monitoring, such as glucose monitoring devices, ECG patches, EEG bands, respiration patches, and wearable devices such as in-ear devices, smartwatches, smart bands, and smart rings to monitor vital signs, as well as diagnostic kits, such as virus diagnostics based on electrochemical theory and animal hormone monitoring devices. We provide the chips, we provide semiconductor chips, and we provide bio signal processing chips to digital healthcare device manufacturers and pharmaceutical companies, and our customers provide the devices to patients. Our management team founded our first company in 2003, which was Radio Pulse, and the company was acquired by a US company in 2015. This is our team members, the second founding company. We have worked together for more than 20 years, and we have nine PhDs and three master's degrees. I can say we have a very high-profile engineering team. Actually, I am from South Korea. South Korea has a strong point in semiconductors and has been a robust player in the semiconductor industry. With our extensive expertise, we can provide very low power, high profile, and very convenient, cheap solutions to digital healthcare device manufacturers and pharmaceutical companies. Thank you very much.
