STS Approach coped with influential representation according whom the world of technology is an ensemble of activities with its own rules, separated from social life, science and nature. Nevertheless researches highlighted as the divide between worlds of technology and other worlds belongs only to the discursive practice. The innovation practice gathers heterogeneous elements, not only "technologies", changing all together during a unique socio-technical process. The essential link among agency, signs, and devices characterize these processes, shaping unified and convergent ensembles, which are been conceptualized as heterogeneous alignments, technological systems, socio-technical networks, or, into the ANT approach, as actor-networks. Coming out from a long series of reflections, the analysis object of a sociology of technology doesn't result anymore as ensemble of human actors touched by a technological object or device, but as a coordinated ensemble of heterogeneous actors, devices and uses, and of their material and symbolic ecologies.
