Scientists and engineers at Seacoast Science, Inc. are developing technology that includes a MEMS-based capacitive platform where specific chemically-sensitive polymers are attached. This means that one technology platform can be easily adapted to multiple chemical sensing requirements.

 
 

Seacoast Science's technology is based on proprietary designs, and includes micromachined detector arrays, readout electronics, custom synthesized polymers and sol-gels and specialized analytical software. Thus, the technology enables the detection and early warning of weapons of mass destruction, toxic industrial chemicals and other hazardous materials.

For each application, a series of polymers are chosen based on their affinity for detecting specific chemicals. These polymers are coated onto a sensor platform and behave like sponges to absorb chemicals from the atmosphere. When a polymer absorbs a chemical, it changes that polymer's ability to conduct electricity, an event that is measured by our sensor. Seacoast Science's technology then identifies the nature and class of chemicals being detected. Our sensors are sensitive to most volatile organic compounds, toxic industrial chemicals, chemical warfare agents (such as mustard and sarin gas), and other gases.

Competitive Advantages

Size  Multiple detector on a single chip
Power Consumption-- W per sensor, mW per system
Cost Semiconductor Processing Techniques
Ruggedness    No moving parts

Seacoast Science, Inc. proprietary sensors have been tested in controlled environmental conditions. Our sensors have demonstrated sensitivity to many Toxic Industrials Chemicals (TIC), Volatile Organic Chemicals (VOC), Explosives, and Chemical Warfare Agents (CWA). The sensors were capable of detecting many hazardous compounds in air in the parts per billion range.
