Benefits of technology

[0025]A sensor can be associated with the base body. Here, it is concretely conceivable for a base body with a cuboidal, parallelepipedal or cylindrical shape to have a sensor on one of its surfaces. If the base body is configured as the sole of a shoe, it could be wedge-shaped. The sensor can detect the change in a magnetic field or the change in a magnetic field strength that results from a deformation of the elastic base body. A Hall sensor could be used as the sensor. Hall sensors are characterized by high resolution and reliability.
[0026]If the base body is configured as the sole of a shoe, the sensor could be embedded in the base body. With this a

DETAILED DESCRIPTION OF THE DRAWINGS

[0038]FIG. 1 shows a permanent magnet comprising a cylindrical base body 1. The base body 1 has a magnetic north pole 2 and a magnetic south pole 3. The base body 1 can be deformed elastically. This is schematically shown in the right-hand drawing in FIG. 1.

[0039]The base body 1 consists of a foam made of ethyl vinyl acetate in which magnetically hard particles 4 of strontium ferrite (SrFeO particles) are homogeneously distributed. These particles have a mean diameter of 0.5 μm to 5 μm. The strontium ferrite 4 was magnetized by an external permanent magnet or by a magnetic pulse in such a way that their elementary magnets are permanently oriented. Therefore, the permanent magnet 1 according to FIG. 1 exhibits permanent magnetization.

[0040]The base body 1 is made of a foam that has pores 6 that are in the range from 10 μm to 3 mm.

[0041]A sensor 5 is arranged on the circular base surface 7 of the cylindrical base body 1 according to FIG. 1. The sens...

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.

Description

[0001]This claims the benefit of DE 10 2007 032 821.6 filed on Jul. 12, 2007, through PCT / EP2008 / 005238 filed on Jun. 27, 2008, both are hereby incorporated by reference herein. The invention relates to a shoe for medical applications as well as to an insole for a shoe.BACKGROUND OF THE INVENTION[0002]Diabetics, in particular, suffer from circulation problems and are especially sensitive to pressure on the skin. Such pressure loads cause pressure sores on the body that can become infected and lead to ulceration.[0003]Shoes known from the state of the art often make use of foams. These foams become compacted over the course of time and thus cannot provide their full springy and cushioning effect. This results in areas in the shoes that can no longer provide springiness and cushioning. This can lead to pressure loads on the feet of the wearer.[0004]Especially diabetics, whose feet easily develop ulceration, suffer the effects of these pressure loads.SUMMARY OF THE INVENTION[0005]There...
