Portable Impedance Based Chemical Sensor

The Problem:
Current chemical sensors (which are used to help detect toxic materials and explosives) are not highly selective or sensitive to detecting the target compounds. This is largely due to non-selective methodologies like DC resistivity. Additionally, they typically weigh more than forty pounds and cost over a hundred thousand dollars. Therefore, these sensors are not versatile nor efficient for the industry.

The Solution:
The invention is an airborne chemical sensor designed to target explosives. Unlike other chemical sensors, this one is AC impedance-based and targets in a sensitive and selective manner. It operates by identifying unique frequency modulations to detect the presence of certain chemical vapors. These airborne chemicals can then be used to reveal the presence of an explosive material.

Benefits:

  • Cheaper and lighter due to AC impedance in a handheld circuit
  • Versatile detection of chemical vapors
  • Faster detection time
  • Removes water, decreasing humidity
