The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can also be associated with food and communicate data about ingestion of food material to a receiver.本發明的系統包括傳導元件、電子組件以及不同形式之異質材料的部分電源。與導電流體接觸時,產生電位且完成電源,如此便啟動系統。電子組件控制異質材料間的傳導率以產生獨特的電流特徵。系統亦能與食品結合並傳遞關於食品材料之攝取的資料。2700‧‧‧接收器2710‧‧‧電極輸入2720‧‧‧穿體傳導通訊模組2730‧‧‧生理感測模組2740‧‧‧溫度感測模組2750‧‧‧加速計2760‧‧‧處理引擎2770‧‧‧記憶體2780‧‧‧無線通訊模組
