SYNOPSIS: This Request for Information (RFI) seeks innovative concepts and technologies from a wide range of stakeholders- including industry, academia, and non-traditional partners- to address the challenge of particulate and vapor infiltration at the interface between worn protective systems. The focus is on mitigating undesired airflow and contaminant ingress caused by pressure fluctuations and dynamic body movement, commonly referred to as the “bellowing effect.” The objective is not to improve current fielded configurations, but to explore forward leaning solutions that inform future research and development efforts across a variety of applications. The Government requests that responses to this Sources Sought be submitted electronically to Juan Fernandez, juan.f.fernandez15.civ@army.mil and Audrey Swartz, Audrey.j.swartz.civ@army.mil no later than August 8th, 2025, by 5:00 p.m. EST. DESCRIPTION: The Joint Project Manager for Chemical, Biological, Radiological, and Nuclear Protection (JPM CBRN P) is conducting market research to identify innovative solutions that address the persistent challenge of contaminant infiltration at the interface between physically integrated protective components worn by individuals. This RFI seeks to understand novel approaches for controlling air and particulate movement across dynamic interface zones – areas subject to frequent motion, stretching, or bending, which can lead to air exchange and penetration of harmful substances. A key issue is the bellowing effect, in which movement-induced pressure changes cause the interface to act as a leak path, reducing the effectiveness of the protective system as a whole. This effort is intentionally broad and not limited to traditional chemical-biological protective ensembles, nor to any specific combination of garments, materials, or equipment. We encourage ideas from across sectors and disciplines, including but not limited to those working in textiles, seals, adaptive materials, soft robotics, wearables, fluid dynamics, and beyond. JPM CBRN P is interested in technologies at any stage of maturity that could reduce or eliminate particulate and gas infiltration through interface points, particularity under conditions of continuous or high-mobility use. Solutions may be component-based, system-level, or even conceptual framework that can guide future integration efforts. This is not a call to upgrade or modify currently fielded systems. Rather, it is an opportunity to explore breakthrough ideas that reimagine how dynamic interfaces manage movement, airflow, and sealing performance in protective configurations. RESPONSES: responses should include as much of the following information as is available: Manufacturer Product name Interface Solution(s) Estimated unit cost for a complete system Production capability Existing government contract vehicles Product Description to include: Description of interface solution and materiel composition, including estimated technology readiness level and/or manufacturing readiness level. Manufacturing details including any unique manufacturing techniques (ex. injection molding), location, and manufacturing readiness levels. Test plans, reports, and any other relevant documentation to support claimed performance characteristics and interoperability performance. Manufacturer production capability, to include maximum and minimum production rates by month. Identify if the system is currently being used by commercial industry and/or government; provide names and/or examples of users. Any data rights assertions/anticipated assertion. Any factors that will significantly impact costs. If there are any significant lead times for materials/systems. If applicable: estimated power usage over 24 hours. If applicable: if the system has reuse capability or decontamination procedures. If applicable: include the weight of the system It is requested that respondents having systems or technologies believed to be suitable as described herein, submit electronic copies of any available product data sheets, related brochures, descriptions, price lists, technical/operator manual(s), test reports, or other documentation as available and deemed appropriate. There is a ten-page limit on submissions outside of any additional documents listed here. Respondents may submit multiple technologies but should clearly identify the advantages/disadvantages of each.
