The Award database is continually updated throughout the year. As a result, data for FY23 is not expected to be complete until September, 2024.
Download all SBIR.gov award data either with award abstracts (290MB)
or without award abstracts (65MB).
A data dictionary and additional information is located on the Data Resource Page. Files are refreshed monthly.
The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: NEXUS PHOTONICS INC Topic: N21BT019
We propose to develop tunable, high-power handling, low-loss phase-to-amplitude conversion photonic-integrated circuit (PIC) based device on heterogeneous SiN platform. The use of SiN for waveguide is the key to meet the stringent requirements, while additional heterogeneously integrated components are the key to enable tuning and locking of the phase-to-amplitude device. Nexus Photonics, realizi ...STTR Phase I 2021 Department of DefenseNavy
SBC: TDA RESEARCH, INC. Topic: N21AT001
Hemp fibers have been used in textile applications for thousands of years, but have been limited to textiles for home furnishing, rope, sacks, and other non-clothing textile applications. However, new treatment methods for hemp fibers to improve their hand, as well hemp’s general softening properties with time and wear, make these fibers attractive for use in performance clothing due to hemp’s ...STTR Phase I 2021 Department of DefenseNavy
Design of a High-Temperature Acoustic Liner for Enhancement of Detonation Wave Dynamics in a Lab-Scale Rotating Detonation CombustorSBC: HySonic Technologies, LLC Topic: N21AT011
HySonic Technologies, founded by Dr. Carlo Scalo, addresses this call by combining its capabilities in design of acoustically absorptive high-temperature materials with Dr. Carson Slabaugh’s (Purdue University) well-established expertise in designing and testing of Rotating Detonation Combustors (RDC) at various scales. HySonic’s history in the design of acoustically absorptive material relies ...STTR Phase I 2021 Department of DefenseNavy
SBC: DYNAFLOW, INC Topic: N21AT013
Decompression sickness (DCS) can occur during rapid pressure changes such as when a diver ascends rapidly or during high altitude flights. Rapid decompression can causes gases dissolved in body fluids and tissues to come out of solution and form bubbles. The symptoms of DCS include painful joints, neurological dysfunction, dermal effects, and cardiopulmonary collapse. Currently, divers rely on dec ...STTR Phase I 2021 Department of DefenseNavy
SBC: INTELLIGENT FUSION TECHNOLOGY, INC. Topic: N21AT016
In order to facilitate collaborative decision-making during modern surface warfare situations, locally learned knowledge among sailors and warfighters must be shared effectively in a timely manner. Current Naval approaches for collecting and sharing knowledge are inefficient and inflexible, as new contents are examined over extended timelines with no ability to dynamically update the knowledge bas ...STTR Phase I 2021 Department of DefenseNavy
SBC: HEAT, LIGHT, AND SOUND RESEARCH, INC. Topic: N21AT010
Both acoustic and electromagnetic waves exert forces of radiation on targets in their path of propagation. The radiation force (pressure) results from the change in wave momentum due to scattering by the target, averaged over one period of oscillation. Modulated radiation pressure (MRP) utilizes the acoustic radiation force by using a double-sided suppressed carrier modulated (DSB-SCM) incident ...STTR Phase I 2021 Department of DefenseNavy
SBC: PC Krause And Associates, Inc. Topic: N21AT012
Advancements in electronic warfare driven by sophisticated sensors and weapons are pushing shipboard power distribution systems to higher voltage, more power dense solutions. Reduced cost and increased flexibility necessitate solutions that are rapidly scalable and are characterized by longer life and lower maintenance. These objectives are in conflict, as increased power density reduces life and ...STTR Phase I 2021 Department of DefenseNavy
SBC: MICRO COOLING CONCEPTS Topic: N21AT012
High power semiconductor devices suffer from difficulty in dissipating heat and thermal stresses. Silicon carbide-based power modules, in particular, have increasingly challenging heat loads despite their high efficiencies. In general terms, the module packaging methods used to improve cooling (moving metal heatsinks closer to the die) also increase thermal stresses, and the methods used to reduce ...STTR Phase I 2021 Department of DefenseNavy
SBC: OCEANIT LABORATORIES INC Topic: N21AT014
In this Phase I project, Oceanit will design a self-healing computing system for use on Navy vessels to keep a ship's primary functions operational in combat should the original computing system be damaged during an attack.STTR Phase I 2021 Department of DefenseNavy
SBC: Handix Scientific Inc. Topic: N21AT015
Light absorption by aerosols is a key component to atmospheric extinction, and affects a number of processes relevant to the Navy. Satellite and other remotely sensed measurements can be strongly impacted by aerosols, obscuring targets and/or confounding interpretation of data products. Directed energy applications, including weapon and communication systems, are also impacted by absorption, which ...STTR Phase I 2021 Department of DefenseNavy
