    Abstract: A flexible electromyographic electrode array and a preparation method therefor, and an electromyographic signal collection apparatus and an electrophysiological signal collection method. The flexible electromyographic electrode array comprises: a flexible substrate (100); several liquid metal electrodes, wherein the liquid metal electrodes are arranged on the flexible substrate (100), and the liquid metal electrodes each comprise a wire and a circuit board connection pattern (110) which is located at one end of a wire (120); and several electrode contacts (130), wherein each of the electrode contacts (130) is connected to the other end of the wire (120), and the electrode contacts (130) are made of a contact solution which contains a hydrophilic polymer and a poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate. The preparation method comprises: printing liquid metal ink onto a substrate material, so as to form a metal electrode pattern; transfer-printing the electrode pattern onto a flexible substrate, so as to form several metal electrodes; and performing plasma cleaning by means of a mask, and dripping the raw material of electrode contacts (130), so as to form the electrode contacts (130). The electromyographic signal collection apparatus comprises a flexible electromyographic electrode array. The electrophysiologic signal collection method comprises: covering the skin surface of a subject with a flexible electromyographic electrode array, and acquiring an electromyographic signal. The electrode contacts have good biocompatibility, high conductivity and low impedance, the tight attachment between electrodes and skin can be realized by means of the electrode contacts, and the impedance of the electrode contacts (130) does not increase due to the loss of moisture, such that the quality of signal recording is prevented from being affected by the generation of noise.

    Abstract: Disclosed are a machining method and a machining device improving machining efficiency and preserving workpiece surface integrity. The machining method improving machining efficiency and preserving workpiece surface integrity includes: setting a workpiece (300) and a machining unit (400); and machining the workpiece (300) by the machining unit (400) at a preset machining speed, wherein the preset machining speed is not lower than a machining speed corresponding to the embrittlement of the workpiece material. The machining device improving machining efficiency and preserving workpiece surface integrity is used for executing the machining method having the same merits. The machining device includes: a base (100) used for mounting the workpiece (300) and the machining unit (400), and a driving unit (200) connected to the machining unit (400) and used for driving the machining unit (400) to the preset machining speed. By the machining method, the machining speed of the machining unit (400) is set during machining, which results in "skin effect" of subsurface damage caused by the embrittlement of the workpiece material (300) and enables the damage depth of the workpiece (300) to be confined in a shallow subsurface layer, so that the damage depth of the workpiece (300) is reduced, the workpiece integrity is preserved, and the machining quality and the machining efficiency are improved.

    Abstract: The disclosure relates to an opto chip (10) for detecting a physical parameter of a liquid sample, comprising an optical structure monolithically integrated with a substrate layer (11) and a functional layer (12), wherein the substrate layer (11) is light-transmissive and configured to have an upper surface (112) for receiving a droplet (20) of the liquid sample and a lower surface (111) bonded to the functional layer (12); and the functional layer (12) comprises a light-emitting region (121) and a light-detecting region (1222) with the light-emitting region (121) being configured to emit measurement light (121a, 122a), and the light-detecting region (122) being configured to receive reflected light (121b, 122b) derived from the measurement light (121a, 122a), wherein a signal of the change in intensity of the reflected light (121b, 122b) is converted into a photocurrent signal. The opto chip (10), viscometer and detection method described utilize a monolithic integrated opto chip (10) and eliminate the need for complex external optical calibration, making the viscometer easy to operate and reducing the overall size of the device. In addition, the chip-scale viscometer provided has a large detection range.
