The design of current small arms ammunition requires the use of radial and lateral accelerations to permit the inclusion
of current Micro Electro Mechanical Systems (MEMS). Research at Louisiana Tech's Institute for Micromanufacturing
into equipping small arms with MEMS technology has led to the development of a new type of small arms system. This
ammunition is able to accelerate outside of its barrel, thereby decreasing the required acceleration for a specified
maximum velocity. Additionally, the design of this ammunition eliminates the lateral accelerations typically required to
stabilize current small arms ammunition, and permits the inclusion of non-metallic barrels and other components. A
review of the current design and performance standards of this ammunition is presented, along with the current MEMS
technology being tested for inclusion into this ammunition. A review of new armament systems, capabilities, and
applications as a result of these advances is also presented.
This paper reports on a low-cost, borosilicate glass-based spectroscopic sensor for the detection of water contaminants.
10 μL water samples are inserted into a sandblasted sample reservoir in a borosilicate glass substrate and are partially
evaporated with a 200 nm thin-film Cr microheater/cathode patterned to the bottom of the reservoir. The relative
contaminant concentration within the partially evaporated sample is greater, providing a means of measuring lower
concentrations of impurities. An on-chip plasma discharge is stuck to the sample, sputtering the water contaminants into
the discharge, doping its spectral emissions. Cu and Fe impurities are detected at 10 ppm in a 2.5% HNO<sub>3</sub> solution and
Ca and Mg contaminants are detected at 100 ppm. The on-chip microheater yields temperature changes as high as 96 °C
when supplied with 100 mA. Multiple single-use sensors can be fabricated inexpensively on the borosilicate glass
substrate using simple, standard photolithography techniques.
