    摘要: A fall detection system includes first sensing devices, second sensing devices, positioning modules, a data server and a display device. The first sensing device is configured to detect a posture of a body part of a user for obtaining body part posture data. The positioning modules are configured to detect positions of the first and second sensing devices, so as to obtain corresponding body part position data. Each of the second sensing devices is disposed on a shoe to detect a posture of a user's feet and to measure a distance from an ambient object for obtaining feet posture data and distance measurement data. The data server is configured to receive the body part posture data, the body part position data, the feet posture data and the distance measurement data to determine if the user falls down.

    摘要: A method for detecting an analyte comprises the following steps: providing a SERS-active substrate and a Raman spectra database; applying a sample onto the SERS-active substrate; applying an incident light by a Raman spectrometer onto the SERS-active substrate to generate a Raman spectrum of the sample; and comparing the Raman spectrum of the sample with a Raman spectra database to identify an analyte in the sample. The SERS-active substrate comprises: a support; a first dielectric layer disposed on the support, wherein the first dielectric layer is formed by a plurality of first nanofibers; and a plurality of noble metal particles formed on the plurality of first nanofibers.

    摘要: A grasping-response evaluation system includes: a base mechanism; a positioning module mounted in the base mechanism; a controlling device operable to control the positioning module to switch between the grasping and releasing states; a bob to be engaged with the positioning module in the grasping state; and a traction rope connected between the bob and the base mechanism. When the positioning module switches from the grasping state to the releasing state, the bob becomes disengaged from the positioning module, falls downwardly relative to the base mechanism, and simultaneously pulls down the traction rope. When a grasping-data collecting device removably disposed on the base mechanism and connected to the traction rope is lifted by a user's hand, it pulls up the traction rope, and measures a grasping force of the user's hand.

    摘要: A modified electrode, manufacturing method thereof and use thereof are provided. The manufacturing method includes steps of: mixing a carbon nanomaterial with 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), followed by drop-casting on a screen-printed carbon electrode, to obtain carbon material modified electrodes; and electrochemically pre-treating the carbon material modified electrodes by cyclic voltammetry technique, constant potential technique, or constant current technique to obtain a modified electrode. 3-Ethyl-6-sulfonate benzothiazolinone imine and 3-ethyl-6-sulfonate benzothiazolone compound are formed on a surface of the modified electrode, and the modified electrode is used for protein analysis, protein immobilization and related biosensor, electrochemical catalysis or biofuel cells.

    摘要: An invisible ink and a method of making the same are revealed. The invisible ink includes anodic aluminum oxide (AAO) powder and at least one solvent. The method of making the invisible ink includes the steps of taking an aluminum substrate and carrying out anodic oxidation on the aluminum substrate at least once to form an anodic aluminum oxide (AAO) layer on a surface of the aluminum substrate, separating the AAO layer from the aluminum substrate and pulverizing the separated AAO layer to get AAO powder, and adding the AAO powder into a solvent to obtain the invisible ink.
