Device for detecting freshness of perishable items
The granted patent US12007375B2 describes a novel device designed to detect the freshness of perishable items. Central to the device is at least one binary sensor that identifies specific analytes within the perishable item. The device integrates an integrated circuit that processes the sensor data and an antenna portion that facilitates both the reception and transmission of signals. Notably, all components are printed on a single sheet, creating a unitary device. The antenna is engineered to harvest energy from an aerial device, which activates the integrated circuit. This circuit is responsible for broadcasting a unique identifier for the perishable item and conducting a pulse test to measure voltage drop data across the sensor, which is then transmitted to an external receiver.
The patent further elaborates on the capabilities of the device, allowing for the inclusion of multiple sensors, each potentially tuned to detect varying concentrations of the same analyte or different analytes altogether. This flexibility enables the device to monitor a range of chemical indicators related to freshness. The aerial devices compatible with the system include technologies such as near field communication (NFC), radio frequency identification (RFID), Zigbee, and Bluetooth, among others. This multi-sensor approach enhances the device's ability to provide comprehensive freshness assessments, making it a significant advancement in the field of perishable item monitoring.
