    摘要: A flexible, polymer-based biosensor deployable into the arterial system which can assess shear stress in the arterial geometry in the presence of time-varying component of blood flow. Also, a method of fabricating a biosensor which may be used for in vivo procedures, involving the sequential depositing onto a substrate of a silicon dioxide layer, a metal heating element on the silicon dioxide layer, and a biocompatible polymer on the heating element, followed by etching the polymer layer to provide holes to allow for electrode contact with the heating element. A second metal layer is then deposited to form electrodes, followed by a second biocompatible polymer layer to form the device structure and removing the fabricated biosensor from the substrate by etching the substrate. In addition, a method of determining intravascular shear stress by measuring the temperature, flow rate and pressure of a bodily fluid with a biocompatible biosensor is disclosed.
