主权项

1. A blood flow meter for monitoring blood flow in a biological tissue comprising (a) a flow sensor comprising a first microelectrode, which flow sensor is capable of being heated by (b) a heater element positioned within 0.5 μm-100 μm of at least a portion of (a), and (c) a temperature sensor comprising a second microelectrode, wherein (a) and (c) are arranged on a flexible substrate and wherein (b) is positioned relative to (c) such that when (a) is heated by (b) to a stable target temperature of 0.5° C. to 3° C. above the temperature of the biological tissue in which the blood flow meter is situated, (c) is not within the thermal influence field generated by (b).
