In situ nano mechanics test

Turn pressure fittings

Turn pressure fittings is unique to the brook of in situ tensile test based on MEMS technology accessories, can realize nanowires in series products of PI or free film tensile test

Due to the 1 d and 2 d uniformly synthetic materials can be quickly, so we need a new mechanical characterization techniques to evaluate and optimize its mechanical properties, so that for the next generation products and devices.In order to solve these new materials provide appropriate test platform needs, brooke developed pressure switch (PTP) over the equipment, the in situ tensile device designed to and is used for SEM and TEM Hysitron PI Series PicoIndenter instrument used in combination.

Inhibits PTP device of the optical image (left) and inhibits PTP device clearance SEM image (right).
Loading/unloading and displacement curve (left), and inhibits PTP device deflection displacement and load with time curve (right).The linear elastic travel distance is greater than 4 microns.

Inhibits PTP device is a kind of MEMS fabrication of flexible devices consumables, can install nanotubes or film sample.After preparation, the sample will be transferred to the PicoIndenter system, and by applying quantitative tensile load.Mechanics data used to calculate the tensile properties and electron microscopy imaging can provide real-time video microstructure behavior.Electric version of the device's "electric pressure turned to pull (E - inhibits PTP)" to further expand its function, can be at four o 'clock in the tensile experiments of electrical measurement.
