I need to connect a piezo sensor to a RFID tag such that when someone presses on the piezo, the voltage generated activates the tag. A nearby RFID reader continuously looks for the tag. The tag remains off/undetectable while the piezo sensor is not touched.
Can I achieve this by removing the antenna on a RFID tag and connecting the terminals to a piezo sensor? The voltage spike can from my piezo sensor can be up to 10 volts. Should I try to limit it before connecting it to the RFID chip.
Also I need this in low latency i.e. small time gap between touch/un-touching piezo and that activating/deactivating tag.
