Provided is an elastic physiological patch, which includes a patch assembly and an implantable assembly. The patch assembly includes an electronic device and a soft patch body. The patch body is provided with a receiving chamber for receiving the electronic device. The implantable assembly can be mounted to the electronic device and includes an implant. The implant can be operably and partially penetrated through the patch body from the receiving chamber and implanted in a human body, and the implant and the patch body jointly seal the receiving chamber. The electronic device is completely covered by the soft patch body, and can be tightly adhered to the implant, thereby closely adhering to the implant to achieve the effect of blocking and waterproofing.一種彈性生理貼片,包含一貼片組件及一植入式組件。該貼片組件包括一電子裝置,及一呈軟質的貼片本體。該貼片本體具有一容置該電子裝置的容室。該植入式組件可安裝至該電子裝置,且包括一植入件。該植入件可被操作地部分自該容室穿出該貼片本體並植入人體,且該植入件與該貼片本體共同密封該容室。藉由軟質的該貼片本體完整包覆該電子裝置,並能緊縮貼覆到該植入件,藉此與該植入件密合而達到阻隔防水的效果。
