Abstract: This paper proposes a 3D printed lens antenna for contactless heartbeat and respiration detection using the millimeter-wave ... A 60 GHz pulsed coherent radar is integrated with the sensor ...

and a wide-aperture electro-optical detecting module with 3D-printed mechanical parts. 3D-printed kinematic mounts of designed detection unit are available for public use as open-source hardware.

This technology, named "Metal 3D printing ... an "add-on" module with aging production equipment that does not have AI applied. The add-on is a module that gathers sensors, defect detection ...
