When we talk about biomedicine and bioengineering, it is hard to believe that they are sciences so closely tied to our daily lives. After all, it’s not like we go to the store on a Saturday to buy a robotic prosthetic right leg. However, even if it seems like fiction or a fantasy story, this is getting closer to our reality than we think.

However, before talking about biomedicine or bioengineering in our daily lives, let’s try to understand a little better what it is about. In itself, its name is quite illustrative. It is a discipline that connects engineering with health, to create equipment, machinery and solutions that help us diagnose, treat, cure and prevent diseases.

You see it? It looks a little closer than you imagined, and now we’ll explain why it’s so important tukif.



To understand why biomedicine is so important in everyday life, just think about how traditional medicine worked 500 or 1,000 years ago. The flu was a disease that could end your life, a broken arm was more than enough reason for an amputation. And like these cases, examples abound with almost all the emergencies that today we consider, although painful, harmless.

The fact that today we can go to the nearest health center and take an X-ray is an achievement of biomedicine, for example. The same is true of many drugs currently available on the market. Its creation was a joint achievement between chemistry and this discipline.

Biomedicine and medical engineering are therefore a way to improve the general quality of life of human beings. Thanks to their work, doctors are able to provide more timely care and save lives.

Those who dedicate themselves to this professional career are currently highly valued in the professional market due to the positive impact that their work brings to their surroundings. Especially in developed countries, where the proportion of the elderly population is much higher.



We already talked about how biomedicine helps the general population. However, one of his greatest contributions is the development of highly sophisticated engineering pieces, which seek to replicate the perfect machine: the human body.

Previously, and going back to amputation a bit, losing an arm meant replacing it with a stick and losing all mobility, if not gangrene killed you first.

Today it is different. Biomedicine has managed to create prostheses that have a design that gives the patient partial or almost total autonomy and mobility, depending on their sophistication. In addition, many of them are designed to replace the lost limb, even aesthetically.

If we get a little more futuristic, it is worth highlighting the great innovations in ophthalmology, with the new ocular prostheses that stimulate the retina and allow an approximation, although rough and rudimentary, to objects and shadows.

What is the most amazing thing about biomedicine for you? Leave your opinion in the comments.

The example of General Stress Optics

High-precision 3D contouring of gears for aerospace industry General Stress Optics has developed the necessary technology to perform high precision contouring. A study was carried out in which the profile of a spur gear was measured using our technology; the results were compared to results obtained via CMM. Below we see the 3-D reconstruction of one gear tooth obtained by us. The results below show that the agreement in between the two procedures is within 1-micron.

Complex geometries or high tolerance requirements push mechanical measuring devices to their limits, with the aid of optical techniques one can obtain fast and highly accurate results. One example is the spiral bevel gear which has a very complex geometry and is difficult to measure using CMM. For that reason most of the time the qualification of a gear is determined via a 9×5 matrix test in which the points are taken along the described matrix. These points are then matched to the master that is also measured and the values are compared. If one wishes to obtain a more detailed analysis it would require increasing the matrix size and thus increase measurement time.

With our technology one can obtain a full field view of the surface and therefore is not limited to a small matrix of points. In this case in order to demonstrate the power of the technique we simplified our measurement to the same matrix and below one can see how well they agree to the points measured via CMM.

Holographic Moiré to new heights. We were able to measure displacements in the nano-meter range.The Bi-Metal Laminate composite that was measured for this experiment had a thickness of 0.008″(~200 microns). The set up that was used can be seen in the images below. An optical bench was attached to an Instron machine, a special fixture was designed to illuminate the surface while the piece experienced the compression. The field of view was 480 x 360 microns and we had resolution in the micron range. With the power of the HMSA we were able to obtain strain values and create graphs that contain the loading and unloading properties of the Bi-Metal Laminate Composite along with a 3-D representation of the strain field at specific loads.
