You should broaden your research scope to make it easier. A rephrase of your goal opens new ways of approaching the problem. Defining a problem too specific cut off many possible solutions.
There are many other ways to rephrase your problem, give it a try.
Thank you for your comments and assistance and ideas
1- Can we use the sensor detector changes in the electromagnetic field of a person dressed explosive belt ... ?
2-Can we account for changes in capacitance sensor by contact between a body and EMF Sensor board ?
3- Are we could use ultrasound sensors to detect changes in the amplitude of the reflected wave echo after tigger at body wearing an explosives belt ?
4- Can we use the waves infrared sensor detector infrared waves to see changes in the body emitting waves of heat before dressing and after dressing as a measure of changes between two values and knowledge of the body that holds the belt of explosives ?
With many thanks and appreciation
