Project Area A
Contactless sensors for recording motion parameters and vital functions
Project area A researches different wave and radio-based sensor technologies for the remote detection of motion parameters of the human body. The targeted new sensor concepts achieve a precision, measuring rate, dynamics and fine-grained resolution in all dimensions (6D pose, 3D body surface and 3D speed with the respective time course of all values) that are at least one order of magnitude better than the current state of the art are.
Coherently phase-sensitive, wave-based sensors such as radar, laser or coherent radio location systems are particularly suitable for measuring both macroscopic and microscopic movement processes remotely with maximum precision, as they are able to evaluate Doppler and micro-Doppler signal phases.
The EmpkinS sensor technologies are selected on the basis that as many different motion parameters as possible can be recorded with the highest possible quality. Since a single sensor cannot optimally record all conceivable parameters equally, complementary sensor technologies are being researched. They cover different types of detection areas (e.g. the entire body shell (sub-project A01) or areas of interest such as the face, neck or arm, leg or chest area (A03, A04). Moreover different orders of magnitude of movement (e.g. movements of the limbs (A02) or micro-fasciculations (A05) e.g. on the face) and / or different areas of application (e.g. measuring vital parameters or the mobility of limbs) are recorded. Depending on the required input variables of the biomechanical neuro- and psychomotor models or depending on the diagnostic question, the different sensor technologies are used individually or in combination.
