An interdigital gold electrode was covered by screen printing films of doped PPBT (DPPBT) to prepare a resistance-type humidity sensor, which exhibits electrical response towards relative humidity (RH%) variations in the range 11%-96%. PPBT shows promise as a new humidity-sensitive material.展开更多

A surface acoustic wave (SAW) delay line oscillator was covered by Langmuir-Blodgett (LB) films of resulting PDEB to prepare a humidity sensor, which was found to have high sensitivity and good repeatability. PDEB shows promise as a good humidity-sensitive material.展开更多
