Smart device knowing location information of the opened containing groove

A smart device, comprising:

• a non-electrical component, comprising a containing structure configured to contain one to a plurality of medicines, the containing structure further comprises a plurality of containing grooves, and the containing grooves are respectively configured to contain at least one of the medicines;
• and
• an electrical component, disposed on the non-electrical component, and comprising a triggering structure and an e-paper display apparatus, wherein the triggering structure is configured to generate a triggering signal to trigger the e-paper display apparatus to display medicine administration information, the triggering structure comprises a plurality of piezoelectric material elements, and the piezoelectric material elements are respectively disposed to the containing grooves;
• and
• a controller, disposed on the containing structure, and configured to receive the triggering signal, so as to control the e-paper display apparatus to display the medicine administration information,
• wherein the piezoelectric material element of the triggering structure is deformed by receiving an external force to generate the triggering signal, the containing groove is opened by the external force and the medicine is removed from the opened containing groove, the triggering signal has an electrical characteristic, and the electrical characteristic is determined by a structure characteristic of the piezoelectric material element , the structure characteristics of the piezoelectric material elements are different from each other, and the controller determines location information of the opened containing groove based on the triggering signal.
