Embedded sensor system for e.g. detecting pressure of automobile system, has measuring section connected with polycrystalline sensor and supplied with energy by power supply for detection of physical parameters or state changes of system
Embedded sensor system for e.g. detecting pressure of automobile system, has measuring section connected with polycrystalline sensor and supplied with energy by power supply for detection of physical parameters or state changes of system
The system (2) has a polycrystalline sensor (4) including a transmission and reception unit, a transmitter and a receiver for reversible transfer of electrical power into mechanical surface waves. A transmission unit (5) sends and receives electromagnetic waves. The transmission unit has a transmission and reception channel that makes connection between an embedded circuitry (3) and the sensor. A measuring section (6) is connected with the sensor and supplied with energy by a power supply (7) for detection of physical parameters or state changes of a system e.g. automobile system.
