Abstract

An integrated sensor chip unit and fabrication method includes a measured-value pickup for determining measurement data and a circuit arrangement for enabling a wireless power supply and interrogation of the measurement data. The measured-value pickup is formed as an integratable sensor, and the circuit arrangement is formed as an integrated semiconductor circuit module. The sensor and the semiconductor circuit module are mechanically and electrically conductively connected to one another using one or more microsystems engineering techniques.
