The invention provides a body sensing pad and a potential therapeutic device having same, so a patient can simply and singly confirm whether potential is applied or not a touch member (1111) and a contraposition member (1113) are arranged at regulated intervals the patient (a person applied with potential (AC wave form) for potential treatment) touches the touch member (1111) of the body sensing pad carried charges (surface charges) of the touch member (1111) change, and force (Maxwell strain) between the touch member and the contraposition member (1113) also changes so as to generate vibration, and the patient can have body sensing potential (AC waveform) applied on body through the vibration.本發明之目的在於提供一種可由被治療者單獨且簡便地確認有無電位施加之體感墊裝置或包含其之電位治療器。藉由空開特定間隔設置觸控構件1111與對向設置構件1113,只要由被治療者(被施加有用於電位治療之電位(交流波形)者)碰觸體感墊裝置111之觸控構件1111,則觸控構件1111之帶電量(表面電荷)變動,藉此作用於觸控構件1111與對向設置構件1113之間之力(Maxwell(馬克士威)之應力)亦變動,故產生振動,並可藉由該振動使被治療者體感自身被施加有電位(交流波形)。111‧‧‧體感墊裝置1111‧‧‧觸控構件1112‧‧‧保護薄片1113‧‧‧金屬箔1114‧‧‧固定構件1115‧‧‧支架構件1115a‧‧‧支持片1116‧‧‧基底構件
