This engineering study examined how a DC bias electric field affects the resonance frequency shift of a PMN-PT/tin piezoelectric microcantilever sensor during humidity detection. The authors report that applying a bias field enhanced the relative resonance frequency shift, with a maximum enhancement of more than…

This laboratory study tested microwave radiation (10 and 60 mW/cm2 for 5, 30, or 60 minutes) on fungal and actinomycetal spores grown on agar and on common building materials under wet and dry humidity conditions. Reported effects on spore viability depended on strain, growth conditions, humidity, power density, and…
