Title:
ELECTROSTATIC CAPACITANCE DETECTION TAG AND CONTAINER WITH TAG
Document Type and Number:
WIPO Patent Application WO/2024/058097
Kind Code:
A1
Abstract:
This electrostatic capacitance detection tag is provided to a container having an accommodation section for accommodating content the upper surface of which changes position in the height direction, and has: electrodes, including a first electrode and a second electrode that is provided at a position that does not overlap the first electrode; an antenna part capable of carrying out noncontact communication with an external device; and an IC chip that is electrically connected to the electrodes and the antenna part, and that measures electrostatic capacitance formed between the first electrode and the second electrode. The IC chip carries out noncontact communication with the external device through the antenna part, and transmits the electrostatic capacitance measured by the IC chip to the external device.
