Completed TRL 3 (started at 2, targeting 3)
The objective of this project is to develop a Piezoelectric Instrument for Precision Exploration Sampling (PIPES). PIPES is a miniaturized liquid sample acquisition and handling system, which looks like a straw and is powered by a hand-held box. The “straw” contains multiple flow paths for parallel sampling. Enabled by 3D printing, PIPES integrates acoustic actuation to achieve multiple sampling functions, including pumping, filtering, and mixing, in one compact unit. The PIPES system seeks to fill a gap in NASA’s current in-flight sensing capabilities: the lack of miniaturized fluidic sampling and handling systems. The PIPES will make dramatic improvements at the system level in terms of weight, cost and operational simplicity. Moreover, as a versatile micro- to meso-scale fluidic sampling system, the PIPES can work with multiple meso- and micro-scale detection technologies such as electrochemical sensors, micromachined chromatographs and miniature mass spectrometers. Therefore, PIPES has great crosscutting potential in biomedical and environmental applications.
PIPES as an integrated end-to-end in situ system will make sampling in space exploration more effective. The low-weight, low-cost and simple operation is particularly suitable for space exploration. PIPES as a versatile system that can work with multiple detection instrument systems has great crosscutting potential in biomedical and environmental applications.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
