Technical Field

[0002] Bionic blood, also known as artificial blood or synthetic blood, is a synthetic substance that can replace natural blood.

[0003] One of the design goals of bionic blood is to simulate the performance and flow characteristics of real blood. Blood viscosity and density are important parameters of blood flow, directly affecting blood flow within blood vessels and the efficiency of material exchange between blood and tissues.
