Nanosensors with high sensitivity utilize electrical, optical, and acoustic properties to improve the detectionlimits. The unique and exceptional properties of nanomaterials (large surface area to volumeratio, composition, charge, reactive sites, physical structure and potential) are exploited for sensingpurposes. The concern about the safe environment on the road, especially during the maintenance and repairing process, the application of Signal Warning Detector (SWAD) be applied to help reduce the percentage of having a fatal accident that involves the maintenance worker and the highway users. This system was created to alert the workers from the danger that will warn them through 3 ways, such as sound, vibration and visual. It is important to develop the transmitter device and the receiver device that can be connected as a wireless system to ensure the worker can move freely while working and not being constricted by the connecting wire. This system is one of the safety procedures for workers while working the highway emergency lanes. The model of the casing is drawn by SolidWorks and static analysis was used to analyze the stress, displacement and strain on the device’s casing suitable with the environment working field to get an appropriate material and mechanical structure design. The analysis for the system based on the design of experiments and demonstration in real situations.
