Asahi Kasei Microdevices announced the launch of its AK581xAIM antenna-in-module (AiM) millimeter wave (mmWave) radar modules. These modules enable highly accurate detection of falls, as well as people’s presence, breathing, position, and posture, without the use of cameras. These sensor solutions accelerate proof-of-concept (PoC) development and the integration of sensor functions without requiring expertise in antenna or radar design.
More and more people are planning to age independently in their own homes – according to a survey by AARP By 2024, the figure in the United States will be as high as 75%. This increases the demand for privacy-conscious support through cameraless systems in the home.
Antenna-in-Module Radar
AKM’s new AiM modules (AK5816AIM / AK5818AIM) integrate the AK581x mmWave radar IC and an antenna array with four inputs and four outputs each in a single compact package (23 mm x 23 mm). The integration of the antenna eliminates the need for a custom RF design, reducing development effort and accelerating time to market. Multi-channel measurements and high angular resolution enable precise 3D detection for vital signs, position, movement, posture, and even falls. The module distinguishes between people, pets, and objects.
Data protection-conscious solutions for a wide range of applications
The AK581xAIM mmWave radar modules offer an unobtrusive, privacy-compliant solution for a wide range of applications. Since no cameras are required, these modules can also be deployed in bedrooms or bathrooms. This enables faster response times in emergencies while reducing the workload on caregivers. The modules can also contribute to increased energy efficiency when used for motion-dependent control of HVAC systems or lighting.
Evaluation kits available for testing
AKM offers two kits to simplify evaluation and accelerate development. The “AIMEZ V” is optimized for rapid proof-of-concept and implementation testing and features USB, Ethernet, Wi-Fi, and Bluetooth interfaces. The “LUMI” is designed for the development of advanced algorithms and is equipped with a powerful system-on-chip (SoC) for large-scale data processing and machine learning applications. Both kits include a basic software environment for rapid setup and support the integration of proprietary algorithms, enabling a smooth transition from evaluation to product development. Asahi Kasei has identified the “Electronics” business area as a strategic growth area. The development of AKM’s new AiM mmWave radar modules and evaluation kits underscores the company’s commitment to continuing to proactively invest in growth and drive innovation.
