Single-use biopharmaceutical manufacturing requires monitoring of critical manufacturing parameters. We have developed an approach for passive radio-frequency identification (RFID)-based sensing that converts ubiquitous passive 13.56 MHz RFID tags into inductively coupled sensors. We combine several measured parameters from the resonant sensor antenna with(More)
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(More)

We give a simple proof of Euler’s remarkable theorem that for a nondegenerate triangle, the set of points eligible to be the incenter is precisely the orthocentroidal disc, punctured at the nine-point center. The problem is handled algebraically with complex coordinates. In particular, we show how the vertices of the triangle may be determined from the(More)
