Abstract
Passive wireless sensing devices [1] make use of an interrogation technique that does not require powersupply or wire-connections to the sensor device, which provides large configuration freedom. A prototype passive wireless sensor, together with the corresponding readout platform, is proposed here. The sensor is a square split ring that responds to impedance changes of microtissue spheroids. The wireless sensing system is used to detect the growth of HCT116 cancer spheroids at a distance of up to 4 mm. Integrated in a culture-well structure, the sensor can be used for automatic real-time detection of microtissue properties in “lab-on-a-chip” applications. Show more
