Problems solved by technology

However, few meat probes on the market meet all the criteria: wireless, battery-free and able to communicate with the oven
The main challenges for wireless solutions are the large chip size of Bluetooth, resulting in large aperture (needle) diameters, and the need for batteries
Analog probes based on surface acoustic wave (SAW) devices are either orientation dependent or expensive for a single precise temperature monitoring location

Abstract

A battery-free sensor probe 10 and system for measuring the temperature of food. The sensor probe 10 includes a probe portion 12 and a handle 14. The probe portion 12 has a temperature sensor 18, a circuit board 16 and a radio frequency identification device 20. The handle 14 has an antenna 26 connected to the radio frequency identification device 20 and the circuit board 16. The sensor probe 10 harvests energy from a radio frequency transmitter 34 positioned near the sensor probe 10.

Description

technical field [0001] The present invention relates to wireless sensor probes for monitoring temperature. In particular, the present invention relates to wireless energy harvesting sensor probes for monitoring temperature in food. Background technique [0002] Proper handling and cooking of food, especially meat, is essential to avoid contamination with disease-causing bacteria or pathogens. The U.S. Centers for Disease Control and Prevention (CDC) estimates that 48 million people get sick each year from foodborne illnesses, 128,000 are hospitalized, and 3,000 die. The U.S. Food and Drug Administration (USFDA) recommends using a thermometer to ensure a minimum temperature of 140°F to 165°F inside the meat during cooking. Smart ovens communicate with temperature probes to enable energy-efficient temperature regulation and prevent the risk of fires due to overheating of unattended food. [0003] The cordless, battery-free meat probe increases product usability and longevit...
