A novel type of negative differential resistance (NDR) is demonstrated in composites incorporating graphite nanoparticles in a silicone matrix. The NDR occurs as the electric field breaks the pi-band of graphite, initiating a semimetal-to-insulator transition. The current peak is robust and tunable with the graphite concentration. This material can produce flexible electronic amplifiers for bioelectronic applications
