▎ 摘　　要

NOVELTY - Low power sensing system suitable for use within a biological organism comprises (a) one or more graphene sensors placed in contact with biological tissue, where the graphene sensors are sensitive to electrical signals originating from the biological organism; and (b) low power digital electronic switch electrically coupled to one or more of the graphene sensors, where the switch is activated by the sensed electrical signals, the biological organism includes nerve cells, and the electrical signals are nerve cell impulses. USE - The low power sensing system is useful as biological sensor, preferably biocompatible neurological sensor (all claimed) which is used in diagnostic applications. ADVANTAGE - The low power sensing system consistently reduces amount of applied voltage, dissipates less power as heat and consumes significantly less power, and is suitable for operating at lower voltages than the operating voltages of larger transistors and devices having minimum dimensions, and convenient to wrap around delicate biological tissues, as graphene has excellent flexibility. DETAILED DESCRIPTION - Low power sensing system suitable for use within a biological organism comprises (a) one or more graphene sensors placed in contact with biological tissue, where the graphene sensors are sensitive to electrical signals originating from the biological organism; and (b) low power digital electronic switch electrically coupled to one or more of the graphene sensors, where the switch is activated by the sensed electrical signals, the biological organism includes nerve cells, and the electrical signals are nerve cell impulses. The graphene sensors are configured as nanowire, and the low power digital electronic switch is a tunneling diode. INDEPENDENT CLAIMS are included for the following: (1) method for constructing the biological sensor system; and (2) biocompatible neurological sensor.
