The invention provides a pressure sensor, and further provides electronic skin, touch screen equipment and safety alarm equipment correspondingly, wherein the electronic skin, the touch screen equipment and the safety alarm equipment are based on the pressure sensor. The pressure sensor comprises a substrate. The substrate is provided with a plurality of sensing units arranged in an array mode; a static nano generator with two friction layers is adopted in the sensing units, when external force is applied to the sensor, the distance between two friction layers of each sensing unit feeling the external force is changed, and electrical signals output outwards by two corresponding electrode layers are also changed; electrode layers of all sensing units are led out of the sensor through wires, so that functions like pressure (stress) positioning and pressure field mapping can be achieved. The electronic skin, the touch screen equipment and the safety alarm equipment do not need to be powered by power supplies and can conduct pressure induction in a self-driven mode.

A flooring system comprising a plurality of electrode pairs in contact with a metaplastic composite material. The metaplastic material is such that it locally conducts electrical current in an area where any load is applied to the metaplastic. An electric potential is applied to one or more interdigitated electrodes located at a face of the metaplastic material in line with applied loads. Larger area coverage can be obtained either by pre-installing a subsurface layer comprising of an array of interdigitated electrodes and their trace line outputs and then covering this layer with a tiling of metaplastic material sheets that is in direct contact with the array of interdigitated electrodes, or, by directly attaching one or more interdigitated electrodes and their output trace lines to an individual sections of metaplastic material and electrically interconnecting their outputs. By applying a sufficient number of interdigitated electrodes and sheets of the metaplastic material and monitoring the electrical current flowing in each interdigitated electrode so placed, it can be determined whether and where loads are being applied to the PCC flooring material and the approximate size and shape of the load.

With these extracted features, the system conducts hierarchical classification at an individual step level and at a collection of consecutive steps level, achieving high degree of accuracy in the identification of individuals.

Fall detection method and systems with its unique designed sensors are disclosed. The capacitive sensing based systems use the abrupt changes of the capacitance value to detect whether a real fall event happens, while the reed sensor/or reed switch based systems work in power saving passive mode to detect the real fall event by analyzing the binary “on/off” signal available from the reed sensor/or reed switch. Both rely on the orientation change of the host body respects to local gravity direction during the falling process. The system can present either as a standalone system or a built-in component with supporting software installed on other devices.
