We address the significant need for the monitoring of critical manufacturing parameters in single-use biopharmaceutical manufacturing by developing passive radio-frequency identification (RFID)-based sensors and their integration into single use bioprocess components. Our sensor development approach converts ubiquitous passive 13.56 MHz RFID tags into inductively coupled sensors. In this work, we...
We demonstrate passive (battery-free) radio frequency identification (RFID) devices for selective and sensitive chemical vapor sensing in the presence of ambient interfering gases. We developed two approaches for RFID sensing (1) when a sensing material is applied onto the resonant antenna to alter its impedance response and (2) when a complementary sensor is attached across an antenna and an integrated...
Single-use biopharmaceutical manufacturing requires monitoring of critical manufacturing parameters. However, the lack of reliable single-use sensors prevents the biopharmaceutical industry from fully embracing single-use biomanufacturing processes. We report here an approach for passive radio-frequency identification (RFID)-based sensing that does not rely on costly proprietary RFID memory chips...
