Freshness detection device for perishable items
The patent application (Publication Number: US20240019390A1) describes a device and system for detecting the freshness of perishable items using sensors and integrated circuits. The device includes sensors for detecting specific analytes in the perishable item, an integrated circuit for processing the sensor data, and an antenna for transmitting the information. The sensors, integrated circuit, and antenna are all printed on a single sheet, making the device unitary. The system further includes a substrate, a radio device for transmitting signals, and a receiving device that converts the signal into a freshness value for the perishable item, which can be displayed on a software application.
Additionally, the patent application also describes a sensor tag for detecting freshness in an environment, with a chemical sensor, integrated circuit, and antenna printed on a paper substrate. The antenna can respond to NFC and RFID signals, and the chemical sensor can be configured as binary or multiple sensors to detect various changes in the environment. The sensor tag is designed to be biodegradable, with a semi-permeable membrane coating the chemical sensor. This innovative technology offers a unique and efficient way to monitor the freshness of perishable items, providing valuable information to consumers and businesses alike.
