Wearable Bluetooth Low Energy Based Miniaturized Detection Node for Blind Spot Detection and Warning System on Vehicles

Annually, approximately 10 people are involved in a lethal blind spot accident on Belgian roads, even though a lot of money is invested in the development of blind spot detection systems and in raising the awareness of this phenomenon. In previous research, we developed a blind spot detection and warning system based on Bluetooth Low Energy (BLE) and received signal strength indicator (RSSI) measurements. In this paper, the miniaturization of the detection node and wearable is presented. There will be a closer look at the development of the Printed Circuit Board (PCB) and the folded Shorted Patch (S-P) antenna that will be integrated into the side lights of trailers. In a future step, the wearable design will be updated with the same miniaturization steps taken in this paper.
