    • A Universal Serial Bus data transport method and its device is disclosed. Data transport is performed through a high-speed transport technique based on a Universal Serial Bus, which consists of Universal Serial Bus protocol for communication between the device and the host, and SCSI protocol for interaction between the device and the upper driver layer. A data transport device using the Universal Serial Bus thus uses the embedded driver inside the operating system, which may be self-loaded/self-initialized, and have high data transport speed, and convenient to use.

    • An exemplary, highly integrated, SPM-based system for measuring the conductivity and/or force of substance under programmable engaging/stretching processes is described. A sample bias is applied across two electrodes. A substance to be measured is sandwiched between them. A first electrode is first brought relative to a second electrode (engaging) in programmable pathways that can be described as stretching distance versus time curves. The process of engaging the electrodes continues until a certain current reached, a certain force reached and whichever case happens first. The electrodes are then separated (stretching) in programmable pathways that can be described as stretching distance versus time curves. A periodic modulation can be applied to the engaging/stretching process to realize different stretch pathways. The sample bias across the electrodes is kept constant or swept in a programmable shape over time, described as a voltage-versus time curve. The conductivity, engaging/stretching distance, and/or force are measured simultaneously.
