A combined transducer capable of bone conduction audio and inertial haptics would enhance situational awareness, but this need has not been met by current technical solutions. In this Phase I SBIR topic A16-019, Vibrant Composites Inc. has extended its nonlinear resonant actuatorNLRA haptics technology towards creating such dual-use component. Initially developed to enable the most precise haptic communication components, NLRA technology has the potential to create a combined transducer core capable of both precise haptic communication and high fidelity bone conduction audio. The transducer design leverages Micro-Multilayer Etched Composite System manufacturing innovations to achieve a miniaturized form factor suitable for integration into a flexible, lightweight head-mounted system. In this Phase I SBIR, Vibrant Composites has delivered functional dual-mode bone conduction and vibrotactile transducer prototypes.
