Shoe for medical applications

Abstract

A shoe with a permanent magnet including a basic body having a magnetic North Pole and a magnetic South Pole and being elastically deformable solves the problem of realizing a shoe which is able to provide its wearer with information about the material properties and the condition of the shoe.

         12 : A shoe comprising:
 a permanent magnet including an elastically deformable base body having a magnetic north pole and a magnetic south pole; and   a sensor associated with the base body for detecting a change in a magnetic field or a change in a magnetic field strength that results from a deformation of the base body.   
     
     
         13 : The shoe according to  claim 12  further comprising a sole, the permanent magnet being positioned in the sole. 
     
     
         14 : The shoe according to  claim 12  further comprising a heel, the permanent magnet being positioned in an area of the heel. and/or in the area of the ball of the foot. 
     
     
         15 : The shoe according to  claim 12  further comprising a ball area for supporting a ball of a foot, the permanent magnet being positioned in the ball area. 
     
     
         16 : The shoe according to one of  claim 12  wherein the base body is made of a foam throughout which magnetically hard particles are distributed. 
     
     
         17 : The shoe according to  claim 12  wherein the base body comprises a foam made of ethyl vinyl acetate. 
     
     
         18 : The shoe according to  claim 12  wherein the base body comprises an elastomer from the group consisting of SBR (polystyrene butadiene rubber), NBR (nitrile-butadiene rubber), EPM (ethylene-propylene rubber), EPDM (ethylene-propylene-diene rubber), EVA (ethyl vinyl acetate), CSM (chlorosulfonyl-polyethylene rubber), VSi (silicon rubber) or AEM (ethylene-acrylate rubber). 
     
     
         19 : The shoe according to  claims 12  wherein SrFeO particles are distributed throughout the base body. 
     
     
         20 : The shoe according to  claims 12  wherein NdFeB particles are distributed throughout the base body. 
     
     
         21 : The shoe according to  claims 12  wherein the sensor is embedded in the base body. 
     
     
         22 : A shoe according to  claims 12  further compring a sole, the sensor giving the wearer of the shoe a signal as to whether the base body or the sole or parts of the sole are already severely deformed due to ageing. 
     
     
         23 : An insole comprising:
 a permanent magnet including an elastically deformable base body having a magnetic north pole and a magnetic south pole; and   a sensor associated with the base body for detecting a change in a magnetic field or a change in a magnetic field strength that results from a deformation of the elastically deformable base body.
