Self-Assembled Integrated Sensor/Actuator Networks

This SBIR program would develop a process for the integration of electrically networked sensors and actuators with physically large composite military structures and platforms. NanoSonic would use its patented electrostatic self-assembly (ESA) process to form elastomeric, electrically conductive patterned interconnects in free-standing plies to allow the interfacing of multiple distributed sensor and actuator elements. ESA involves the layer-by-layer deposition of polymers, nanoclusters and other molecules to form functional thin films with a wide degree of control over multiple constitutive properties. Recent work has demonstrated the ability to control these properties both through the thickness of the film as well as patterned in the plane of the film. Patterned functional films may be co-cured into advanced polymer matrix composites without affecting structural integrity, yielding an integrated multifunctional structural/electronic component. Free-standing network plies may also be applied as decals to the surfaces of composites. During Phase I, NanoSonic would work with major corporate partners and leading research universities to design, fabricate and evaluate the performance of sensor and actuator network-integrated and networked composites. During Phase II, NanoSonic would work with defense industry partners to transition this technology to composite structural platforms to provide mission performance and health monitoring information.
