    With the development of automobile driver assistance systems and automatic driving, the practical use of auto-motive Ethernet (100BASE-T1, 1000BASE-T1) using UTP (Unshield Twisted Pare) cables as a high-speed and high-capacity communication standard has been progressing. In order to ensure the reliability of these automotive Ethernet systems, EMC testing of automotive Ethernet systems is required. In this study, the pulse disturbance applied to these UTP cables by the indirect ESD test is estimated by calculating the common mode current flowing in the UTP cable from the excited electric field and considering the mode conversion at the end of the UTP cable. The threshold value that causes communication failure was derived by introducing the estimated pulse disturbance into the 100BASE-T1 communication simulation.

    In recent years, wearable robots that are worn on the human body have been attracting attention for their applications in the medical, welfare, and industrial fields. A wearable robotic hand can perform various motions by controlling motors of the electric hand with biological signals such as myoelectric signals and brain waves. Our research group has been working on the wireless control of wearable robots by using human body communication (HBC) in the 10-60 MHz weak radio band. The wireless communication using human body communication does not require an antenna, and the bio-signal detection electrode and the human body communication electrode can be shared, which is expected to reduce the circuit size and im-prove convenience. In this paper, we report on method of sharing the bio-signal detection electrode and the human body communication electrode, as well as a countermeasure for the inter-interference caused by the sharing.
