In another sensor-related interview from ipXchange at CES 2024, Guy chats with Chris about Asahi Kasei Microdevices’ (AKM’s) latest 60-GHz millimetre-wave radar sensor. In this case, AKM demonstrates use of its technology in partnership with Pontosense for an in-cabin monitoring solution that can wirelessly detect whether a child or animal has been left unaccompanied in a car. But that’s a gross oversimplification!
As Chris explains, AKM’s devices set themselves apart from competitor solutions with vastly improved detection accuracy. Using a 3D antenna placed at the middle of the car’s roof/ceiling, AKM’s solution can detect not only the complete occupancy of the vehicle, but it can also detect a child’s heartbeat and breathing, even when the child is covered with a blanket.
Should the child stop breathing, the car knows and can alert someone to come help, but more appropriately, it can notify the driver if they have accidentally left a child or animal in the car. It is clear how AKM’s device can be used to greatly increase vehicle safety as this could also be used to auto-disengage airbags or adjust the deployment mechanism according to the passenger.
Other applications for AKM’s millimetre-wave radar sensors include fall detection for the elderly – in this case it allows patients/residents to maintain their privacy as there is no video feed – but the ultra-high accuracy also means that these devices can be used to create wireless stethoscopes, which could change the landscape of medical wards in an already demanding working environment.
