Program Solicitation: Higher-Order Composite Resonators for Extra resilience (HORCREX)
Office: Defense Sciences Office (DSO)
Proposal Due Date: 16 February 2025 by 1600 (ET)
Description: The Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO) is issuing a Disruption Opportunity (DO), inviting submissions of innovative basic or applied research concepts in the technical domain of novel micromechanical oscillators for applications toward precision positioning and navigation systems. This DO is issued under the Program Announcement for Disruptioneering, DARPA-PA-24-04. HORCREX aims to advance the development of high-performance inertial sensors by addressing the challenges of achieving both excellent sensitivity and resilience to shock and vibration in a single sensing proof-mass. The concept of mode-locking provides a possible pathway to achieve a spectrum of operational frequencies, including low-frequency modes which can then be used to demonstrate extended dynamic range (low noise and shock and vibration resilience). DARPA is interested in exploring a variety of methods, including different methods for transducing multiple vibration modes of a sensing proof-mass and for managing frequency variation and relative phase fluctuations across the full dynamic range of operational conditions. Regardless of chosen approach, each performer should fully explore the design space through modeling, characterization, and experimentation of mode families, materials, transducers, and locking mechanisms to stabilize a multiple-mode mechanical sensing platform. HORCREX will thus improve sensor survivability and ensure sensor operation through extremes of dynamic range, such as pinpoint landing of an unmanned aerial vehicle (UAV) in a turbulent weather system.

DARPA reminds you to check out “Working with DARPA: Global Participation and Engagements” – an online training module for global participants interesting in learning about how to work with DARPA. This module is available on DARPAConnect – an online platform that aims to broaden DARPA’s reach and stimulate growth and collaboration with small businesses and education institutions new to the national security space.
DARPA relies on global partnerships with fellow members of the international science and technology ecosystem to achieve its mission. In this module, you will learn more about opportunities for global participants to work with DARPA, helpful hints and tips for members of the international community, and success stories from previous DARPA programs with contributions from organizations outside of the United States.
