Cover layer (2) the skin region under being the system and the method of informing about the occurrence of the humidity in (2), the operational expedient which operates (6) it has disclosure expedient the detection expedient which detects the occurrence of the humidity in the skin region under cover layer the disclosure expedient which exposes at least the portion of the skin region to the temperature lapse where most corresponds to the temperature lapse which occurs when it does not have (4) and cover layer (5) and due to the control of detection expedient. Being disclosed expedient, power source (7) with, following to the specified curve which brings the output temperature of the electric/temperature conversion expedient which almost corresponds to the temperature lapse which occurs when it does not have electric/temperature conversion expedient (5) and cover layer, the control means which control electric current or voltage may have (6). Electric/temperature conversion expedient may have the Peltier element of one or more.カバー層(2)の下の皮膚部位(2)における湿気の発生を知らせるシステムおよび方法であって、カバー層の下の皮膚部位における湿気の発生を検出する検出手段(4)と、カバー層がない状態で発生する温度経過に大部分が対応する温度経過に皮膚部位の少なくとも一部をさらす曝露手段(5)と、検出手段の制御によって曝露手段を動作する動作手段(6)とを備える。曝露手段は、電源(7)と、電気/温度変換手段(5)と、カバー層がない状態で発生する温度経過にほぼ対応する電気/温度変換手段の出力温度をもたらす所定カーブに従って、電流または電圧を制御する制御手段(6)とを備えてもよい。電気/温度変換手段は、1つ以上のペルチェ素子を備えてもよい。
