Bioengineering Approaches to Energy Balance and Obesity (SBIR R43/R44) | Apply Online

Opportunity Summary:

The Bioengineering Approaches to Energy Balance and Obesity (SBIR R43/R44) opportunity, Funding Opportunity Number PA 07 435, is a National Institutes of Health (NIH) small business grant program focused on creating and testing new bioengineering technologies that can help researchers and clinicians better understand and address problems tied to energy balance. In practical terms, it targets the measurement and modification of how the body regulates energy intake (what and how much people consume) and energy expenditure (how the body uses energy through metabolism and activity), with the longer-term aim of supporting progress on weight control and obesity. The emphasis is on tools and technologies that can move the field forward by making energy balance research more precise, scalable, and clinically relevant.

A key feature of this announcement is its strong push toward innovative instrumentation and engineering-driven solutions. NIH is looking for projects that develop and validate novel sensors, devices, imaging methods, and other technical approaches that can be used to study or monitor eating behavior, metabolic processes, physical activity, and related physiological signals. The announcement explicitly expects these technologies to be developed and evaluated through collaboration between engineers and physical scientists, together with researchers from disciplines such as obesity, nutrition, physiology, behavioral science, or other relevant areas. That multidisciplinary angle is central: the goal is not just to invent a gadget, but to create something technically sound and biologically meaningful that can answer real research questions in energy balance and ultimately be usable by the broader scientific community.

The program is structured under the SBIR mechanism, meaning it is intended for small businesses developing products or enabling technologies with a clear development pathway. It supports Phase I (R43) work, typically aimed at establishing feasibility and developing early proof-of-concept, and Phase II (R44) work, which generally focuses on full development, optimization, validation, and steps that position the technology for broader use or commercialization. The opportunity also allows Fast Track applications, which combine Phase I and Phase II into a single submission to speed the transition from feasibility to development if the project is well positioned to move quickly. The announcement also notes that it runs in parallel with a companion FOA of the same scientific scope, PA 07 436, which uses the STTR mechanisms (R41/R42). The practical difference is that STTR requires a formal partnership with a non-profit research institution, while SBIR has different collaboration requirements; applicants choose the track that best fits their team structure and R&D plan.

In terms of what NIH expects these projects to accomplish, the central deliverable is a useful technology or research tool that expands what scientists can measure, image, model, or intervene on in the context of energy balance. While the immediate objective is to equip researchers with better tools to study energy intake and expenditure, the announcement makes clear that the eventual downstream impact should be to support therapeutic advances and behavioral changes related to obesity and weight management. That means successful projects are likely to be those that can demonstrate a credible link between the technology being developed and how it will enable new insights, better monitoring, improved interventions, or more effective translation into clinical or real-world settings.

Administrative and eligibility details matter for this program. The funding instrument type is a grant, and it falls under discretionary funding. There is no cost sharing or matching requirement. Eligibility is limited to small businesses, and foreign institutions are not eligible to apply, which is consistent with SBIR program rules. The opportunity was originally posted on August 20, 2007, with multiple receipt dates (rather than a single deadline), and it was later archived on September 5, 2010. The size and duration of awards are not fixed in the announcement because projects can vary widely in scope and maturity; NIH indicates that budgets and timelines will depend on the mechanism used (Phase I, Phase II, or Fast Track), the scientific and technical merit of applications, and the proposed costs and duration.

The announcement is associated with several CFDA numbers reflecting the cross-cutting health relevance of energy balance research, including 93.286 (Discovery and Applied Research for Technological Innovations to Improve Human Health), along with areas tied to cancer research and control (93.393 and 93.399), cardiovascular diseases (93.837), and aging research (93.866). That mix signals that NIH views obesity and energy balance technologies as broadly applicable across major disease areas where weight, metabolism, nutrition, and activity play meaningful roles. For applicants, this reinforces the value of framing the technology not only as an engineering advance, but also as a tool that could be widely useful for studying or improving health outcomes in multiple related domains.
