mechanical or electrical/electronic engineering?
(OP)
Hello!
What is the most crucial type of engineering, in order to develop a sensor? or an implantable cardiac pacemaker? or a system to measure a substance in blood? other medical devices?
ofcourse I understand that other professionals are needed, like biologists, chemists, doctors, physicists, etc, but between mechanical and electrical/electronic engineering, which is more essential?
thanks!

What is your desire, mech or elect? Do you have the aptitude for one?

It's quite surprising that mech engs make those sensors, because I 'd expect elects to make them!

I am worried about your comment to the OP.
Now in general I see here and in other forums a growing tendency of criticizing very quickly (jumping at very first possible occasion) new/inexperienced people. The pattern is specific and often it is finger pointing to attitude problems with sort of statement "you will go no where with that attitude".
It often happens more and more when (green) people complain about that they are uncomfortable with a boss, with a coworker, when they feel not valued etc.
Yes years of experience matter, definitely. But I am getting quite annoyed becomes its is becoming predictable harsh comments.

RE: mechanical or electrical/electronic engineering?
What about MEMS devices in sensors? That's more mechanical than electrical. Peristaltic pumps? Same. Microfluidic devices for blood testing, as the OP mentioned? Mechanical.
I could create a similar list with "chemical" after them all, or "bio", or, or, or...

Your impact as an innovator will be dictated more by your personality than your education. You're either a creator or you're not.
RE: mechanical or electrical/electronic engineering?
I may rephrase my question in order to become more understandable
what prevents us from having now a device that detects blood glucose without having to draw blood?
I doubt that an unsolved mechanical property prevents us
is it the correct signal processing? is it the correct radiation properties? not sure
but I doubt it's a mechanical problem that prevents us
RE: mechanical or electrical/electronic engineering?

"but I doubt it's a mechanical problem that prevents us"
How do you know? What is your basis for this assertion? What makes you think it's that easy to measure glucose? Do you really think that millions of people want to prick their fingers multiple times a day?

RE: mechanical or electrical/electronic engineering?
I suppose a test strip with a reactive material comes in contact with blood, reacts with glucose and in a concentration-dependent way, this reaction changes the electrochemical properties of the reactive material, which digital signal is processed and results in the measurement of glucose
the question is, will we be capable to measure the glucose non-invasively? there are many attempts, so it seems yes
but what is the role of mechanical engineers in this technological advance? chemists may play a role, physicists may play a role, electronic engineers may play a role, but what about mechanical engineers? are they only for the packaging of the device?
RE: mechanical or electrical/electronic engineering?
You seem to think you know about sensors already. Pick a field that interests you.

If not for the packaging and materials design how would they do this: http://www.medtronicdiabetes.com/treatment-and-pro...

RE: mechanical or electrical/electronic engineering?
and I cannot see that a simple package, a box to include inside few chips is as important as the heart of the device
am I missing something?

Initially I thought it was ignorance on the OP's part that prevented him from initially seeing the importance of the other fields... with his repeated attempts at downplaying the other fields, despite our attempts to convince him otherwise, now I'm leaning towards youthful arrogance and naiveté.

You answered your own question. You want to be an electrical engineer.

I chose a job with loads of fluid dynamics (compressible and incompressible), heat transfer & thermo, much signal processing and control design, loads of newtonian mechanics, ODEs and PDEs. Quite a lot of simulation and programming too.
Mech would need quite a big pigeon-hole.

RE: mechanical or electrical/electronic engineering?
It depends on your area.
I work with mechanical engineers that have never designed a part in their life. They wouldn't know where to start.
But, they know materials and basically do what you describe.
I also work with electrical engineers that design PCB's along with test equipment/tooling.
These days having a working knowledge of a mix of disciplines helps with your future, and helps the company.

Please don't tell me what it is that I do with my Mech Eng degree. You'd be surprised.

RE: mechanical or electrical/electronic engineering?
You continue to ask questions about ME components of electronics, which is NOT the right question. MEs play critical part of the overall efficiency of an electric car, and it's not just only about the battery. If that's the way you think about systems, you and your company will fail miserably. Systems are always compromises between critical requirements. CFD, as mentioned above plays a critical role in lowering the aerodynamic drag of the vehicle, and the ability of the car's thermal controls to keep the batteries and equipment from overheating. An efficient "packaging" job means there's more room for more battery. A better "package" means the battery could take less room and be more efficient in volume and weight. Efficiency in the drive train determines how much power is consumed per mile, regardless of how efficient the battery is.
