Sense’s Exclusive Explosives Sensor Technology

Brief Technology Introduction.
This new explosives sensor technology is based on Micro Electro-Mechanical Sensors (MEMS). These microstructures are fabricated in a very similar fashion to mass produced electronic integrated circuits. MEMS can be designed as sensors for a wide diversity of physical, chemical and biological applications. At the present time, these microstructures are commercially manufactured for a number of applications, ranging from atomic force microscopes (AFM) to deceleration sensors for automotive airbag deployment systems (SRS). MEMS based chemical sensors are fabricated in the form of extremely sensitive microcantilever structures.

Microcantilever sensors operate by detecting changes in resonance response or deflection caused by mass loading, surface stress variation or changes in damping conditions. Specifically, microcantilevers designed as explosives sensors are coated on one side with a chemical substance designed to absorb specific explosive molecules. An absorbed molecule induces the respective microcantilever to immediately undergo changes in deflection or resonance response. Induced changes in individual microcantilevers can then be detected and measured in real-time by a suitable microprocessor based system.

The fundamental advantages of this new hand-held explosive detection technology are very low cost, extremely high sensitivity and real-time operation. A proof-of-principle prototype is currently operating at Oak Ridge National Laboratory. Several US Government Agencies have invested approximately ten million dollars in the development of MEMS based sensor technology.

The Technology Development Program.
During the past two years, scientists at Oak Ridge National Laboratory (ORNL) have made remarkable progress towards the realization of a lifelong dream. This scientific dream has been the rapid and accurate detection and identification of chemical substances utilizing sensor chips very similar to mass-produced electronic integrated circuits. These new chips are called Micro Electromechanical Sensors (MEMS).

Last year, ORNL won the very prestigious R&D100 Product of the Year Award for a handheld explosives detector using MEMS technology. Due to these very significant scientific advances, Sense Technologies (Sense) and ORNL have jointly decided to undertake a final effort towards the development of a commercial explosives sensor chip with unique high performance capabilities. Towards this end, Sense has entered into a technology development agreement with ORNL. Under this agreement, Sense will provide ORNL with the required funding levels necessary to complete the development of this explosives sensor chip within the next 18 to 24 months.

Initially, this MEMS sensor chip will be capable of quickly and accurately detecting most explosives used by terrorists. Additionally, system modularity will greatly facilitate upgrading fielded systems as new detection capabilities are continuously expanded.

The Product Development Program.
Sense has also begun an intensive internal effort to develop a high performance hand-held explosives detector system utilizing this sensor chip. Immediately thereafter, Sense intends to apply to the pertinent regulatory agencies for the required approvals. Manufacturing and marketing operations for this product are tentatively scheduled to begin during the second half of 2007.

In the first quarter of 2007, Sense also plans to begin an internal effort to develop a very comprehensive and sophisticated cargo container security monitoring system for which Sense is in the process of applying for a US Patent. This effort will draw on the experience gained during the previous development effort.

The fundamental architectural criteria will be primarily focused around system modularity and field-upgrade capabilities, both designed to extend the technical longevity of fielded systems. These two fundamental capabilities protect the initial acquisition investment and thus provide an additional level of buyer comfort.
The Potential Customers.

The advent of a low cost, high-performance hand-held explosives detector, opens a whole spectrum of marketing possibilities. Some of the more obvious clients are national security agencies, customs, law enforcement agencies, fire departments, armed forces, private security firms and humanitarian organizations. The following is a partial list of the more obvious facilities, where such a product would have a very significant beneficial impact on existing security levels:

Transportation Infrastructure:
Airport facilities, subway stations, railroad stations, passenger bus terminals, maritime ports and marinas, cruise ships and ferries, commercial cargo and mail transportation companies, car and truck rental facilities (Inspections on vehicle return).

Product Distribution and Training.
Sense plans to create a national and international distribution networks consisting of reputable and well-established representatives and distributors of brand-name security products. These organizations will also be responsible for extensive operator training and responsive technical field support.

Several months prior to the commencement of manufacturing operations, Sense plans to establish a technical training facility in South Florida. This facility will ensure the appropriate level of technical expertise expected of all the personnel involved in sales, security management, security screening and field support.

The US National Market.
Actual security market projections are very difficult to ascertain, especially in the present security conscious environment. Conservatively, Sense believes that for a high performance, hand-held explosives detector with a price of under $2,000 there is an initial market of 1000 test units for the first year, followed by 10,000 units for the second year and 30,000 units for the third year.

Presently, there does not seem to be on the horizon, any other explosives detector technology with a price/performance ratio comparable to that of MEMS. Therefore, Sense believes that it can quickly achieve a dominant market position as a manufacturer of high performance explosives detectors.

Sense’s marketing strategy includes the generation of recurring revenues from the sales of new and refurbished replacement sensor cartridges, sensor cartridge upgrades, maintenance contracts, software update programs and technical training.

The International Markets.
Sense believes that the export market represents a market potential as large as that of the US. To satisfy this export market, Sense plans to create a distribution network consisting of reputable and well-established representatives and distributors of brand-name security products. These organizations will also be responsible for extensive operator training and responsive technical field support. Sense will sequentially address the US market, followed by the European, the Middle Eastern and Latin American markets.

Product Development and Manufacturing Capabilities.
Sense has brought together a very strong professional product development team consisting of project managers, electronic hardware engineers, software engineers, mechanical engineers, industrial engineers and technical writers. Sense has also created a Scientific Advisory Board that directs and oversees all of the Company’s research and development activities. In addition, if needs arise, Sense also has access to significant professional resources from local universities and engineering subcontractors.


Presently, Sense prefers to concentrate all of its resources on product development, marketing and technical field support. Therefore, highly qualified and experienced local contract manufacturers will perform most product manufacturing.

Sense has all of the required resources necessary to fully cooperate in all respects with ORNL in the development of this technology. Furthermore, Sense also has all of the required resources necessary to develop, manufacture and market all applications of this technology.

Sense intends to establish itself as a broadly recognized manufacturer of superbly crafted instruments designed for rugged real-world field applications. Towards this end, rigid emphasis will be placed on engineering excellence, strict quality control and professionally responsive field support.

The Competition.
A number of companies are manufacturing and marketing hand-held explosives detectors. These products operate under various scientific principles completely unrelated to Sense’s proprietary MEMS technology. All of these competing detectors are much larger, heavier and significantly costlier than Sense’s MEMS detector. Sense believes that its proprietary detector technology is significantly superior to all other existing technologies.

Oak Ridge National Laboratory.
Oak Ride National Laboratory (ORNL) is the US Department of Energy’s largest science and energy laboratory. Managed since April 2000 by a partnership of the University of Tennessee and Battelle. ORNL was established in 1943 as a part of the secret Manhattan Project to pioneer a method for producing and separating plutonium.

During the 1950’s and 1960’s, ORNL was an international center for the study of nuclear energy and related research in the physical and life sciences. The creation of the US Department of Energy in the 1970’s, led to an expansion of ORNL’s research program into areas of energy production, transmission and conservation. By the turn of the century, the laboratory supported the nation with a peacetime mission that was just as important, but very different from the days of the Manhattan Project.

ORNL has a staff of more than 3,800 and approximately 3,000 guest researchers who spend two weeks or longer each year at Oak Ridge. ORNL funding for FY2005 exceeds $1 billion. UT-Batelle has provided more than $6 million in support of math and science education, economic development and other projects in the greater Oak Ridge region.

ORNL is an international leader in a range of scientific areas that support the Department of Energy’s mission in the Office of Science. The laboratory’s six major scientific competencies include neutron science, energy, high performance computing, complex biological systems, advanced materials and national security.
