In present study, electronic vests were designed by using conductive textile material and electronic circuits. The objective was to sense armed assaults and transmit the coordinates and position of gun fire instantly to the headquarters. Another objective is to provide instant emergency respond for injuries at vital sections of the body and to capture perpetrators quickly. To reach the desired targets, silver-coated conductive yarn, polyamide plain weave and various circuit components were used. Silver-coated conductive yarn was used to form sensor unit of the electronic vest and stitched over polyamide fabric in 3mm intervals. Main vest section was prepared in medium size and conductive-yarn sensor unit was installed to the vest with a velcro system. Classical and Surface Mount Device (SMD) circuit technologies were used in circuit units to sense bullet intrusion and transmit the case to operational center. Two different circuit designs were tested at a shooting range and the outcomes were assessed and compared for two different circuits. It was observed in shooting tests that both vests were able to sense bullet intrusions in case of an assault and to transmit the shot message with the coordinates and position of the shoot correctly.
