Transcutaneous Recharge: A Comparison of Numerical Simulation to In Vivo Experiments

Three-dimensional analysis model of electric heating fabrics considering the skin metabolism

“…Before the simulation, material parameter definition and boundary condition constraints are required. Under standard atmospheric pressure, the setting parameters and constant values 21,33,35–38 are shown in Table 2. The above linear thermal radiation coefficient h r can be calculated by formula (12), 34,39 the external environment temperature is set to T a = 283 K, the physical properties of blood tissue under the skin tissue surface:…”

“…The thermal conductivity and thickness of other layers are shown in Table 1. 20,33,34 In order to ensure that the contact area of each layer is large enough to get a good convergence result, the length, width, and height are set as 14 mm × 14 mm × 6.2 mm. The size of the carbon fiber heating element embedded in the fabric is: 2a × 2b × H carbon = 0.2 mm × 4 mm × 0.2 mm.…”

“…Before the simulation, material parameter definition and boundary condition constraints are required. Under standard atmospheric pressure, the setting parameters and constant values 21,33,[35][36][37][38] are shown in Table 2. The above linear thermal radiation coefficient h r can be calculated by formula (12), 34,39 the external environment temperature is set to T a = 283 K, the physical properties of blood tissue under the skin tissue surface: In order to understand the heat transfer state in the electric heating fabric-skin tissue, the heat source temperature inside the electric heating fabric is transferred to the skin surface and the external environment.…”
