I2C Touch Sensor

Is there any way to purchase additional touch feelers for the Grove touch sensor without purchasing a whole new unit? They don’t appear to be listed on the site but the controller has an additional 4 headers, and I have a project that could use 5 of them.

Maybe, you can refer to another product: Grove-Q Touch Sensor (seeedstudio.com/depot/GroveQ … Path=25_33), you don’t need any headers, because so many products can used as herders.
