The work reported here is motivated by the discovery of far more important role played by the sub-Kolmogorov scales than commonly believed. The first part is devoted to an overview of main results and issues that prompted the present developments. The emphasis is made on a number of manifestations of nonlocal nature of turbulence involving direct and bidirectional coupling of conventionally-defined inertial and dissipative ranges showing (a) that both concepts are ill-posed and (b) that further progress requires sub-Kolmogorov resolution. The second part contains a presentation on design, manufacturing and tests in laboratory of a micro-hot-film sensor using modern micro-fabrication technologies, as a basis for a probe of much smaller scale than available today with access to quantities like vorticity and strain at sub-Kolmogorov scales in high-Reynolds-number flows.
