An apparatus for detecting fall-down includes a storing unit, an angular velocity measuring unit, an acceleration measuring unit, an acceleration extracting unit(15), and a fall-down determining unit(16). The storing unit stores fall-down data vectors. The angular velocity measuring unit measures an angular velocity value. The acceleration measuring unit measures an acceleration value. The acceleration extracting unit extracts a kinetic acceleration value and a gravitational acceleration value by filtering the acceleration value measured by the acceleration measuring unit. The fall-down determining unit converts the angular velocity value which is measured by the angular velocity measuring unit, and the kinetic acceleration value and the gravitational acceleration value which are extracted by the acceleration extracting unit, into a fall-down data vector, and determines a user's fall-down by comparing the converted fall-down data vector with the fall-down data vector stored in the storing unit.

Abstract:
A pressure sensor for an electronic skin and a fabrication method of a pressure sensor for an electronic skin are provided to read intensity of pressure, unable to obtain from a conventional pressure sensor using pressure-dependant conductive rubber. A pressure sensor for an electronic skin includes a pressure-dependant conductive rubber(1), electrodes(2,3), an elastic rubber(4), a voltmeter(10), an ammeter(20). The elastic rubber is a substance for making the pressure-dependant conductive rubber slowly react on the pressure. The elastic rubber disperses the pressure applied to the pressure-dependant conductive rubber. When an elastic coefficient of the pressure-dependant conductive rubber is k1, an elastic constant of the elastic rubber is k2, a total elongated length is x, and an elongate length of the pressure-dependant conductive rubber and an elongated length of a buffering rubber are respective x1 and x2, formulas such as x=x1+x2 and k1x1=k2x2 are established. A pressure representing a change of conductivity is applied by x1. Since actually elongated length x is dispersed into x1 and x2, change of resistance is dull.
