Living technology is a field of technology that gets its usefulness from life-like properties—the same traits that make living organisms work. It sits at the crossroads of artificial life and complex systems and matters beyond biology, including nanotechnology, information technology, artificial intelligence, environmental technology, and how wemanage human society.

In simple terms, living technologies are designed to gain their value from life-like behavior. They are characterized by robustness, autonomy, energy efficiency, sustainability, local intelligence, self-repair, adaptation, self-replication, and evolution—properties that current technologies often lack. By making technologies more life-like, engineers hope to create systems that are smarter, more resilient, and better suited to real-world needs.

The broader idea of technology includes not just physical tools but social tools and institutions. Governments, healthcare systems, economies, and laws can be thought of as technologies we design and improve to benefit society.

The term living technology was coined in 2001 by Mark Bedau, John McCaskill, Norman Packard, and Steen Rasmussen. It comes from ideas in artificial life and complex systems, but with an engineering focus: building technologies whose life-like properties emerge from the interactions of many smaller parts, rather than from a fixed blueprint.

This approach has driven several projects. The European project Programmable Artificial Cell Evolution (PACE) helped establish the European Centre for Living Technology (ECLT) in Venice. The Protocell Assembly project at Los Alamos explored similar ideas. The European Commission funded follow-up efforts, and in 2007 the Center for Fundamental Living Technology (FLinT) started at the University of Southern Denmark. A big ongoing vision, Sustainable Programmable Living Technologies (SPLiT), was proposed in 2010 and ranked highly, though it did not receive funding at that time.

Today, living technologies are becoming more life-like and intelligent. They promise powerful capabilities with less environmental disruption, greater sustainability, fewer failures, and better alignment with human needs and ways of interacting with technology. Research tends to be bottom-up: system properties emerge from how parts interact, rather than from detailed, top-down design. The goal is adaptive systems that can develop over time like ecosystems.

Ethical questions come with living technology. These include how to safely create life-like entities, safety concerns if such systems proliferate, ecological impacts on biodiversity and privacy, and who is responsible for ongoing processes rather than finished products. Projects like PACE have addressed some of these issues with guidelines.

There are many versions of living technology, from simple, life-like features to more advanced forms. Across the spectrum, the core idea remains: technology that derives its main function from life-like properties rather than purely non-living mechanisms.
