Battery-free TPMS
The latest vehicles use a TPMS system without any little batteries in the sensors - it relies on the centrifugal action for energy. Do any of the aftermarket TPMS systems for trailers use this tech...

Remember this when you were a child?
If there were innovators that were not willing to think outside of the box as many on this forum seem not willing to do we would not have the Apple watch and cell phones.
A batteryless TPMS sensor or one that can be recharged due to wheel motion is probably in the future.
Think about it. The force on a valve stem while the wheel is in motion is not constant. There is still gravity acting on the valve stem which explains why rubber valve stems do not work well with external TPMS sensors.
