An electrical stimulation apparatus and an electrical stimulation method are provided. The electrical stimulation apparatus includes an electrode unit, a measurement unit and a stimulation unit. The electrode unit is used for contacting a tissue of interest (target tissue). The measurement unit is coupled to the electrode unit. The measurement unit measure a tissue characteristic of the target tissue. The stimulation unit is coupled to the measurement unit and the electrode unit. The stimulation unit stimulates the target tissue through the electrode unit by using an electrical stimulation signal, and the stimulation unit determines amount of charge of the electrical stimulation signal according to the tissue characteristic measured by the measurement unit.一種電刺激裝置與電刺激方法。電刺激裝置包括電極單元、量測單元以及刺激單元。電極單元用以接觸目標組織。量測單元耦接至電極單元。量測單元透過電極單元量測該目標組織的組織特性。刺激單元耦接至電極單元與量測單元。刺激單元透過電極單元以電氣刺激訊號刺激該目標組織，且依據量測單元所量測的組織特性決定該電氣刺激訊號的電荷量。
