3D audio assistance blades
HARTING Mitronics AG, Switzerland, a company of the HARTING Group, Germany, is noted for its expertise in Molded Interconnect Device (MID) technology, a 3D contour-following electromechanical embedded technology. A hearing aid (Figure 2) currently in production at Siemens Audiological (Medical), Germany, using MID technology was runner-up for the Hermes Award for product innovation at the Hannover Messe Fair, and won the MID Industrial Prize at Productronica in Munich. With MID technology, Siemens Medical can use three directional stereoscopic microphones and ear-to-ear wireless communication to enable simultaneous 3D hearing with optimized adaptive noise cancellation in a device smaller than traditional hearing aids, so it is practically embedded in the human ear. HARTING Mitronics used a laser system from LPKF, Germany, in a laser direct structuring process to produce the MID devices.
