Glossary Term
Technology Readiness Level (TRL)
Definition
Technology Readiness Level (TRL) is a systematic metric used to assess the maturity of a particular technology, from its inception to its potential for deployment in real-world applications. TRLs range from 1 to 9, with each level representing a stage in the development process. TRL 1 is the basic concept and research phase, while TRL 9 represents a fully operational system that has been tested in real-world conditions. In the context of the MedTech industry, TRLs help organizations evaluate the technological maturity of medical devices, diagnostics, and other health technologies, enabling informed decision-making regarding development, funding, and regulatory approval.
Relevance to the MedTech Industry
TRLs are crucial for guiding the development of new medical devices and technologies. They provide a clear framework to evaluate the stage of development, highlight areas that need improvement, and inform decisions regarding clinical trials, regulatory submissions, and commercialization. TRLs are used by investors, manufacturers, regulatory bodies, and healthcare providers to assess the risk and potential of a medical technology. Understanding the TRL of a product allows stakeholders to manage expectations, allocate resources effectively, and ensure that the technology meets safety, efficacy, and regulatory standards before it reaches the market.

The Range of Technology Readiness Levels
TRL 1 – Basic Principles Observed:Early research begins, and fundamental scientific principles are observed. There is no practical application at this stage, but the basic concept for a potential technology is identified.
TRL 2 – Technology Concept Formulated:Initial applications of the technology are proposed based on scientific principles. Feasibility studies are conducted to explore the potential uses of the technology.
TRL 3 – Proof of Concept Demonstrated:The technology’s feasibility is demonstrated in a controlled environment, typically through laboratory-based experiments or simulations.
TRL 4 – Technology Validated in Lab Environment:The technology is tested in a laboratory setting with more realistic conditions to validate its core functionality and assess performance against key metrics.
TRL 5 – Technology Validated in Relevant Environment:The technology is tested in an environment that closely resembles real-world conditions, often through pilot projects or preclinical studies.
TRL 6 – Technology Demonstrated in Relevant Environment:The technology has been demonstrated in a simulated operational environment or through small-scale clinical trials, showing that it works in the intended real-world context.
TRL 7 – System Prototype Demonstration in Operational Environment:The technology is now demonstrated in a fully operational environment, such as through field trials or larger clinical studies, validating its readiness for deployment.
TRL 8 – Actual System Completed and Qualified:The technology has been fully developed, tested, and verified in real-world conditions. It is considered ready for mass production and commercialization.
TRL 9 – Actual System Proven in Operational Environment:The technology is fully deployed and operational, with real-world use proving its functionality, reliability, and performance in the intended environment.

Prototype Testing: The process of testing early models or prototypes to evaluate the functionality and design, often used to validate a product at lower TRLs.
Preclinical Studies: Research conducted on animal models or laboratory conditions before clinical trials, typically associated with TRLs 4 and 5.
Clinical Trials: A critical step in moving a technology through TRLs 6–9, involving testing the product with human subjects to confirm its safety and efficacy.
Regulatory Approval: The process of gaining approval from regulatory bodies such as the FDA or EMA, which is essential for moving products to higher TRLs and ultimately to market.
