Technology maturity framework

Technology Readiness Level

Thermowafer uses the nine-level Technology Readiness Level (TRL) framework to communicate maturity with clarity. It is a disciplined way to distinguish a formulated concept from laboratory validation, prototype demonstration, and operational deployment.

The definitions on this page follow NASA’s published TRL framework. See sources.

TRL 2

Technology concept formulated

One approved Thermowafer platform entry is currently listed below. The indicator is manually maintained and is not an automated score.

Portfolio overview

Current project maturity

This overview is intentionally concise: it states what the company is prepared to claim today and identifies the evidence still needed to advance.

Assigned maturity

TRL 2

Concept / application formulated

Explore the framework

Wafer-scale MEMS micro-compressor and integrated cryogenic thermal-management platform

Core semiconductor cooling technology

TRL 2

Current basis

The platform concept and its intended application have been formulated. Current work emphasizes high-fidelity multiphysics simulation, resonant MEMS architecture optimization, and engineering of the enabling subsystem for chip-level cryogenic cooling.

Why not TRL 3 yet

Thermowafer is not presenting this platform as having completed experimental critical-function proof of concept. Advancing beyond TRL 2 requires documented analytical and experimental evidence validating the relevant key parameters.

Nine-level scale

The TRL framework

TRL 1 is the earliest research stage. TRL 9 represents successful operation in the final operational context. The descriptions below are concise, visitor-friendly restatements of NASA’s published definitions. [1]

1

Basic principles observed and reported

Scientific knowledge is generated that underpins a proposed technology concept or application.

2

Technology concept and/or application formulated

A practical application is identified, but it remains speculative and does not yet have experimental proof or detailed analysis supporting the concept.

Thermowafer’s current approved level
3

Analytical and experimental critical-function proof of concept

Analytical studies and laboratory demonstrations, modeling, or simulation validate predictions for key parameters.

4

Component and/or breadboard validation in a laboratory environment

A low-fidelity component or breadboard demonstrates basic functionality and relevant test environments are defined.

5

Component and/or breadboard validation in a relevant environment

A medium-fidelity system or component demonstrates overall performance in a simulated operational environment.

6

System/subsystem model or prototype demonstration in a relevant environment

A high-fidelity prototype demonstrates operation under relevant critical environmental conditions.

7

System prototype demonstration in an operational environment

A high-fidelity engineering unit demonstrates performance in the actual intended operational environment and platform.

8

Actual system completed and qualified through test and demonstration

The final configuration is demonstrated through test and analysis for its intended operational environment and platform.

9

Actual system proven through successful mission operations

The final product is successfully operated in an actual mission or operational environment.

How we use TRL

A TRL designation does not replace technical verification, reliability testing, manufacturing qualification, or system-level validation. It is a transparent maturity marker that helps partners and funding stakeholders understand the current evidence boundary.

What advancement requires

Progress from TRL 2 to TRL 3 requires documented analytical and experimental results that validate critical-function predictions. Further advancement requires increasingly representative components, relevant-environment demonstrations, and ultimately successful operational use. [1]
