Compact and Connected – 3D-Circuits Revolutionizing Wearable Medical Devices

Imagine you need a hearing aid in the future. Today’s hearing aids are quite large and are often visibly placed behind the ear.  Wouldn’t it be great to have an in-ear hearing aid which is almost invisible without any limitations? This is where 3D-Circuits come into play, curious?

What is 3D-MID? 
3D-MID stands for Mechatronic Integrated Device, also known as 3D-Circuits. This technology is a manufacturing technology which integrates circuits directly into three-dimensional thermoplastic substrates. For example, the housing of a hearing aid, which is needed anyway, is used to support the circuitry on its inside, and a separate circuit board can be replaced. This technology enables the seamless combination of electronic and mechanical functions in a single component, which also eliminates the need of additional connecting points for the antenna. By eliminating these requirements, in-ear devices can be made as small as possible, which not only makes hearing aids nearly invisible, but also improves performance and comfort. This is achieved through customer-designed shapes for a perfect fit to the ear, improving sound quality and minimizing power consumption by reducing the weight of the entire component.

Functional Integration and Miniaturization 
Functionality and size constraints are paramount concerns in hearing aids and other medical devices. Here’s where 3D-MID’s technological prowess shines:

Function Density
With 3D-MID, the integration of both electrical and mechanical functions reaches new heights. The result? A higher function density that enables you to pack more capabilities into the same space. This advancement facilitates your pursuit of miniaturization, without compromising on the range of functions, for example improving sound quality and reducing power consumption for hearing aids.

Space Optimization
The quest for function integration and miniaturization doesn’t just save space and weight; it transforms how wearable medical devices are designed and utilized. Imagine delivering enhanced capabilities within a sleeker and more comfortable form factor. With 3D-MID, this imagination turns into reality. For example, hearing aids should be as small as possible, adapting the shape of a human ear and running without having any problems.
