a The practicality picture and 3D visualization of the μ-TED. b The 2nH changes with diameter D and thickness H of TE elements. Here, 2nH represents the total length of the thermoelectric legs per unit area. c Airflow sensing simulation of μ-TED with different TE element diameters. d Airflow sensing simulation of μ-TED with different TE element thickness
