Actually you could do it with a Raspberry Pi which has a motion sensor device (the computer runs about $100 full equiped). Essentially the motion detector would reset a timer every time motion was detected. The systems can be networked with wifi. The motion detector looks for a heat source and sends a signal to the computer when a heat source is found.
I am really suprised no alarm company which has all the tech has yet put this together. Alarm.com has pieces of the tech, such as motion detectors, bed sensors etc.
In the full idea you would monitor activity in the kitchen such that if no one entered there for say a day (a changeable time limit) an alarm as well as the bathrooms. It is is likley that the Japanese may have such tech but it has not made it here yet since they have a bigger problem with older folks.
