Featured Solutions
Interactive AgeTech Solutions
Fall detection, presence & movement tracking
AKM will showcase the fall detection system, which recognizes people’s falls, presence, and movement.
The system does all this without the use of cameras to offer life-saving monitoring without compromising privacy or independence. This solution uses AKM's antenna-in-module (AiM) technology, which combines antennas and AKM's AK5816 60 GHz mmWave radar transceiver into one unit. Its design provides an easy-to-use, ready-made solution with extremely low noise performance compared to the conventional approach, where antennas are integrated into the device package.
Battery-free smart diaper
This diaper features a reusable component that enhances elderly and infant care by detecting the presence of liquid, even with a few drops on the electrode.
This moisture generates a tiny amount of voltage (~300 mV), which is then amplified by AKM’s AP4470L ultra-low-power boost converter to power the product without batteries or complex electronics. The technology can then wirelessly send data to caregivers using AKM’s AK1595A Bluetooth® Low Energy transmitter, thereby reducing the discomfort associated with prolonged wetness.

Wearable health monitoring
AKM will also demonstrate a wristband-based thermometer featuring the AK9757P.
This minuscule infrared temperature sensor, measuring just 1.60 × 1.76mm, integrates seamlessly into wearables such as hearing aids, earbuds, and smartwatches, enabling continuous, non-invasive health monitoring with negligible impact on battery life. It can measure temperature accurately within ±0.2°C even in the presence of a small air gap, allowing for early health issue detection and more personalized care.
