Sensor apparatus, sensor system, and method for operating a sensor apparatus

Sensor system, comprising a write and/or read head and at least one sensor apparatus, said sensor apparatus comprising:

• a receiving device by way of which the sensor apparatus is wirelessly suppliable with electrical energy;
• a sensitive device comprising one or more sensor elements each configured as a measuring probe;
• at least one data processing device which is signal-operatively coupled to the sensitive device which processes data of the sensitive device and provides edited data for transmission;
• a transmission device coupled to the at least one data processing device by way of which the edited data are wirelessly transmittable;
• and
• a device for an interruption-tolerant operation of the sensor apparatus with respect to the electrical energy supply;
• wherein:
• the device for an interruption-tolerant operation of the sensor apparatus is a device for an interruption-tolerant data processing which prevents an irretrievable data loss in the case of insufficient electrical energy supply of the sensor apparatus;
• the device for an interruption-tolerant operation is realized by at least one of hardware and software of the sensor apparatus;
• at least one of the at least one data processing device and the device for an interruption-tolerant operation are realized on a microcontroller;
• and
• the write and/or read head wirelessly provides electrical energy to the at least one sensor apparatus.
