I'm trying to repair a broken baby monitor and found an interesting looking part. It looks like an thermocouple but I'm not sure. Do you have any ideas?

To me, this looks more like a thermistor than a thermocouple.
Can you measure the resistance across this part? If it's zero Ohms (short), then it's a thermocouple. If it's on the order of 10kΩ at room temperature, then it's a thermistor.
What materials are the wires made of? If they are both copper, then it's certainly not a thermocouple.
Can you describe what was this connected to inside of the unit? If it's connected directly to the microcontroller, then it's probably a thermistor. Thermocouples have weaker signal than thermistors, so they require more signal conditioning.
