Printed sensor packaging device and design method based on magnetic resonance wireless power supply technology

Abstract

The invention discloses a printing sensor packaging device and a design method based on magnetic resonance wireless power supply technology. The device includes a printed coil, a printed circuit, a printed capacitor and a printed sensor arranged inside a packaging box; The sensors are connected to each other through printed circuits, and the printed coils and printed capacitors are connected in parallel to form the receiving end of the magnetic resonance wireless power supply. There is a transmitting end of the magnetic resonance wireless power supply outside the packaging box, and the receiving end receives the electric energy of the transmitting end. It is transmitted to the printed sensor to realize the internal monitoring function of the packaging box; among them, the printed coil, printed circuit, and printed capacitor are all printed on a piece of PET plastic film with conductive ink, and the PET plastic film is attached to the inside of the packaging box. The invention enables the package to realize the function of monitoring internal conditions without affecting its volume and weight.

Description

technical field [0001] The invention relates to the technical field of wireless power supply printing sensor packaging, in particular to a printing sensor packaging device and design method based on magnetic resonance wireless power supply technology. Background technique [0002] Magnetic resonance wireless charging technology consists of an energy sending device and an energy receiving device. When the two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy with each other. [0003] The carbon-based water-based conductive ink can conduct electricity through graphite particles in the ink, and its conductivity is close to that of copper, so that flexible printed circuits can be realized. Printed sensors, taking temperature sensors as an example, the volume of conductive ink added with elastic resin will change at different temperatures, which is manifested as a change in resistance, so it can be used to detect temperature...

Problems solved by technology

[0004] Since the conventional solution hopes to add a sensing function to the transportation package, however, having a built-in battery in the package will increase the cost and bring safety hazards to the transportation. At the same time, it is difficult to control the on-off of the external operation control circuit; It causes a lot of inconvenience to handling and transportation, and setting sensors in the package will squeeze the inner space of the package
