Abstract—Recent microwave nondestructive measurement in Ⅱ. DIELECTRIC MEASUREMENT OF BIOLOGICAL
biomedical engineering are reviewed. A novel method for non- MATERIALS
contact monitoring of stress-induced autonomic activation
through the back of a chair is developed, using pact 24 GHz Three probes were developed: a bining two
microwave radar (8 × 5 × 3 cm), without large scale equipment laminates, micro-electromechanical systems (MEMS) based
and placing a heavy burden on the monitored individual. This probe with a single benzocyclobutene (BCB) layer on a quartz
method appears to be promising for future monitoring of stress substrate, and another MEMS probe with two BCB layers
induced autonomic activation of operators and may reduce stress defined on a silicon substrate. The third probe was specifically
induced accidents. A novel in vitro test of blood analysis based on designed for monolithic integration with driving circuits on a
the measurement of the dielectric properties at microwave single substrate. Limitations in the high frequency
frequencies is reported. T
