Sensor ingancin ƙasa

Za a iya gaya mana ƙarin bayani game da tasirin salinity akan sakamakon?Shin akwai wani nau'in tasirin capacitive na Layer biyu na ions a cikin ƙasa?

Zai yi kyau idan za ku iya nuna mani ƙarin bayani game da wannan.Ina sha'awar yin ingantacciyar ma'aunin danshin ƙasa.

Ka yi tunanin idan akwai cikakken madugu a kusa da firikwensin (misali, idan firikwensin ya nutsar da shi cikin ƙarfe na gallium na ruwa), zai haɗa faranti na capacitor da juna don kawai insulator a tsakanin su ya zama siriri conformal shafi akan allon kewayawa.

Waɗannan na'urori masu ƙarfi masu arha, waɗanda aka gina akan kwakwalwan kwamfuta 555, yawanci suna aiki a mitoci a cikin dubun kHz, wanda yayi ƙasa da ƙasa don kawar da tasirin narkar da gishiri.Yana iya zama ƙasa da ƙasa don haifar da wasu matsaloli kamar shayarwar dielectric, wanda ke bayyana kansa azaman hysteresis.
