quantum tunneling polymer composite

https://doi.org/10.1351/goldbook.08862
Electrically conducting polymer composite that, however, is conducting only when pressed due to thinning the insulating polymer matrix membranes so much that they allow electron tunneling through them.
Note:
Quantum tunneling polymer composites are utilized as pressure sensors and touchable control panels of electronic devices.
