Paper Abstract

Traditional micro-fabricated inertial measurement devices like MEMS accelerometers, gyroscopes, and IMUs consist of two principle components: (1) a micromechanical structure that responds to inertial forces and deforms in a way that can be measured electronically by, for example, changing the height of a gap, and, thus, its capacitance; (2) an analog or digital computing device that integrates the electronically sensed acceleration to yield velocity and position, and then records this information for later use. These two components must be replicated in some fashion in a "nano" version of the same devices, specifically a nano-IMU is considered. The proposed approach combines an inertially-sensitive nanostructure or nano fluid/structure system with a micro- or nano- sized chemical reactor that functions as an analog computer. This paper will outline the feasibility of using a cantilever-based acceleration-sensing valve to feed reactants into a first order chemical reaction. The proposed approach to the development of a nano-IMU would allow the benefits of existing MEMS IMU technology to be applied to an even broader array of applications by enabling the development of a new class of geospatially-sensitive drugs and materials and has application in a variety of military, intelligence, and commercial activities.
