Keywave Technology is a fabless semiconductor company founded in December 2022 that specializes in radio frequency (RF) integrated circuit (IC) design and advanced radar sensing solutions. Capitalizing on the explosive growth of Edge AI and opportunities for technological innovation, the company builds ultra-low-power microwave radar chips, modules and spatial sensing devices to track multiple targets with centimeter-level precision spatial positioning applications.
Keywave Technology currently business focuses primarily on the UK market, where it has achieved significant success in projects spanning lighting, energy-saving systems, HVAC optimization, and smart applications involving precise occupancy tracking, smart environmental sensing and human-machine interaction.
Jenny Cheng, founder and CEO of Keywave, established an office in Zhubei as early as 2023 and marked a strategic expansion into Taiwan's core semiconductor and electronics ecosystem. Recognized strong growth of Taiwan’s electronics manufacturing and semiconductor market, she formally launched an "Asia Business Division" team in 2026 with over 20 members.
Following collaboration and engagement with major Taiwanese electronics manufacturing, and OEM/ODMs, Keywave has developed two radar sensor product lines, operating at 5.8 GHz and 24 GHz targeting markets such as AI robotics, smart spaces, smart buildings, automation, and edge AI sensing. Through proof-of-concept (PoC) initiatives and product design, the Keywave R&D team has focused on applications requiring high-precision spatial sensing and trajectory tracking. These innovative products, characterized by high accuracy, rapid sensing capabilities, energy efficiency, and cost-effectiveness. Now these solutions are being officially introduced to Taiwan’s industrial internet of things (IoT) and automation sector, paving the way for new business opportunities.
MP Kan, VP of Technology and CTO at Keywave, outlined the shortcomings of traditional microwave radar and infrared (PIR) sensing technologies. Benchmarked against radar devices from leading global analog integrated circuits (ICs) manufacturers, he identified the primary drawbacks of these existing solutions: false detections leading to unintended activations, a technical inability to detect motionless objects or resting human bodies, and issues regarding high costs and excessive power consumption.
In contrast, Keywave KW007, the compact 5.8GHz ultra-low-power radar sensor, achieves exceptional efficiency by drawing only 30µA to 100µA of operating current, enabling continuous motion detection for years on a single AA battery depending on sensitivity and the selected detection distance.
This exceptional energy efficiency relies on smart sensing algorithm with proprietary multi-dimensional "Space and Time" sensing technology. This approach differs from traditional radar designs, which utilize high-performance DSP chips and extensive memory, resulting in inflated costs and high power consumption.
In June 2026, Kan was invited to France to attend the inaugural European Semiconductor FSNP Meetup. Held on June 4, 2026, at Château de Seguin near Bordeaux, this was an exclusive, invitation-only event for the semiconductor industry, co-hosted by the European chip R&D platform EuroCDP and Silicon Catalyst.EU. He presented this ultra-low-power microwave radar sensing technology based on time-and-space correlation algorithms. The technology’s key strength lies in its integration of proprietary "Spatial Intelligence" and trajectory tracking, enabling it to accurately distinguish actual human movement from environmental noise in dynamic settings. It currently supports a sensing range of up to 20 meters and effectively prevents false triggers caused by natural wind, indoor fans, vibrations, or environmental noise.
By combining radar sensors with AI technology, Keywave KW307, a 24GHz human presence and occupancy sensing module, enables the development of advanced, intelligent applications capable of detecting not only people and objects but even micro-motions like typing, breathing, or minor gestures. Given the regulatory restrictions in EU’s General Data Protection Regulation (GDPR) and California's CCPA/CPRA regarding the major concerns of camera-based systems capturing real-person images or personal identifiers, Keywave’s radar sensors have secured a significant market advantage by measuring motion, distance, and velocity.
These microwave radar sensors facilitate applications such as office occupancy monitoring, object trajectory analysis, and climate and lighting control, while integrating seamlessly with the Industrial IoT devices, robotics, and smart home sectors to rapidly expand the scope of smart use cases. Kan also revealed that the next-generation radar sensor currently under development aims to push detection boundaries from a few hundred meters to several kilometers. This will explore the business potentials for deeper integration with drone and robotics applications to assist autonomous systems with spatial awareness and reliable presence detection in variable or low-light conditions.
The most impressive technological breakthrough of Keywave Technology lies in its ability to achieve precise stationary presence detection and micro-motion tracking by analyzing the minute chest movements caused by breathing, even when a person is completely motionless. The current popular demonstration of Smart Spaces include powering privacy-compliant occupancy tracking for automated lighting and optimized HVAC adjustments. There are more use cases in the industrial controlling and detecting systems.
The company is currently actively forging partnerships across various sales channels, including IC distributors, ODM/OEM manufacturers, and system integrators. In addition to offering engineering evaluation kits, development boards and support to technical teams, Keywave is seeking strategic partners to collaborate closely on the co-design of new applications with hardware and software system integrators.
For further viewing the ultra-low-power radar porducts of Keywave, the company will exhibit at Microelectronics UK 2026, taking place at ExCeL London on September 29–30, 2026. The showcasing booth stand is located at Stand G16, ExCeL London, Royal Victoria Dock. At Keywave, we have been working on exciting new developments designed to help our partners navigate complex engineering challenges, optimize performance, and drive innovation. Visiting our booth will give you an exclusive look at our latest product demonstrations, upcoming technology roadmap, and a chance to speak directly with our technical experts.
