Abstract

At present, the earhook of hearing aid devices has to be bended in the right position manually. The idea is to use a special material that consists of a shape memory alloy. The production itself stays the same. By using this material with shape memory effect, the earhook can be twisted and turned or squeezed in any direction in a way that it does not look like before (see Figure 1).

Shape Memory Alloy for Earhooks

Idea: Benjamin Neumann, SG-Singapore; Harald Klemenz, SG-Singapore

At present, the earhook of hearing aid devices has to be bended in the right position manually. The idea is to use a special material that consists of a shape memory alloy. The production itself stays the same. By using this material with shape memory effect, the earhook can be twisted and turned or squeezed in any direction in a way that it does not look like before (see Figure 1). By applying heat afterwards the earhook will readjust to its original position and form. This is for users very convenient if the bearer accidentally steps or sits on the hearing instrument and bends the earhook. In this case the user just needs to heat it in water, with a blow-dryer or another method like a specially designed tool for such incidents.
