In this laboratory experimental research work, the potential rise of conductive fabrics due to lightning impulse currents is investigated. The potential rise is obtained by measuring the voltage drop across the following representative human body lying face-up position contact points: head-to-heel, head-to-coccyx or head-to-scapula. With the conductive fabric potential rise, the energy transferred to the 1 kΩ human body model is calculated. This investigation let us to assess the possible use of a conductive fabric sheet to protect the human life against ground lightning currents.
