A mobile device for detecting an electrical signal generated by an ingestible event marker is disclosed. The mobile device includes a detection subsystem to receive an electrical signal generated by an ingestible event marker from a detection arrangement. A processing subsystem is coupled to the detection subsystem to decode the electrical signal. A radio subsystem is configured to transmit the decoded electrical signal to a wireless node. A system includes the mobile device and the detection arrangement. A method includes receiving the electrical signal generated by the ingestible event marker at the mobile device, decoding the electrical signal to extract information associated with the ingestible event marker, and transmitting the information to a wireless node.揭露偵測可吞食事件標誌產生的電性信號的行動裝置。行動裝置包括偵測子系統以接收來自偵測配置的可吞食事件標誌產生的電性信號。處理子系統耦接至偵測子系統以解碼電性信號。無線電子系統設定以傳送解碼的電性信號至無線節點。系統包括行動裝置及偵測配置。方法包括接收在行動裝置中可吞食事件標誌產生的電性信號,解碼電性信號以提取關聯於可吞食事件標誌的資訊,以及傳送資訊至無線節點。
