A device and system for collecting and judging patient behavior information. The system includes a device and a server for collecting and judging patient behavior information. The device for collecting and judging patient behavior information includes a thermal energy sensing module, a network module, a computing module, and a power management module. The thermal energy sensing module is used to sense the thermal energy information of a patient and its surroundings. The network module is used to receive the background information of the patient through the network routing server. The computing module is used to calculate the thermal energy according to the default behavior model. Information and background information determine the patient's current and upcoming behavior. The computing module also sends a notification signal to the server according to the behavior, and the power management module is used to supply the power required for the operation.一種患者行為資訊收集及判斷裝置及系統，系統包括患者行為資訊收集及判斷裝置以及伺服器。患者行為資訊收集及判斷裝置包括熱能感測模組、網路模組、運算模組以及電源管理模組。熱能感測模組用以感測一患者及其周邊之熱能資訊，網路模組用以透過網路由伺服器接收患者之背景資訊，運算模組用以依據預設之行為模型，並根據熱能資訊與背景資訊判斷患者目前及即將進行之行為，運算模組還根據行為發出通知訊號至伺服器，以及電源管理模組用以供應運作所需之電源。
