Fig. 5: Simulation and experimental setup for the development of ToSCom.
From: Touchscreen communication (ToSCom): Electro-Quasistatic body communication during touch sensing
a The complete touchscreen communication (ToSCom) receiver (Rx) setup with two small electrodes is illustrated. b Finite-element-method (FEM) based Electromagnetic simulations are performed using Ansys High Frequency Structure Simulator (HFSS). The structure of the transmitter (Tx) and touchscreen receiver (Rx) is illustrated. The complete structure of the touchscreen is developed using Autodesk Fusion 360. c The experimental setup is shown, with the transceiver setup being an Electro-Quasistatic Human Body Communication (EQS-HBC) based Wi-R evaluation kit by Ixana. The receiver setup for measuring channel loss is created using a buffer for high impedance termination, which is connected to a TinySA spectrum analyzer.
