I must admit I didn't see that one coming. It suggests a fascinating application, which is to wear a graphene condom, on top of a rubber condom, on top of a graphene condom. Thus creating a condom 'super capacitor' [1] that you would charge up by rubbing it, which could then power a piezo electric vibrator. I'm so waiting to see who patents that!
