mechanical or electrical/electronic engineering?

[worldman]

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!

 

[worldman]

I would seperate a materials scientist with a biomaterials specialization, from a mechanical engineer

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?

No, you are not "missing" something, you are continually ignoring something. Without the packaging, there is no product; there's just a bunch of parts on a board. No package that small is "simple."

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

I have a VERY strong feeling a mech was involved in designing the implantable sensor for the unit IR linked to.

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.

I was leaning toward abandoning this thread... whoops! there I go... gone...

TheTick,

You are right ...by the way I am gone too

what is the role of mechanical engineering in improving the charging time and the range of an electric vehicle?

A. Designing the car.
You answered your own question. You want to be an electrical engineer.

Funny, my work as a mechanical engineer rarely involves packaging. Or designing. Or materials, or stress, or structures, or manufacting for that matter. I wasn't interested in things like that.

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.

Steve,
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.

Ok. My comment was made for the OP. Put in simpler words:

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

OP, again, ASK the right question, and save yourself needless diversions.

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.

Save yourself the trouble and go electrical. You seem to be trying to find faults with mechanical engineering so just don't become one.

 

[1gibson]

To find faults, he'd first have to acknowledge that ME's do anything other than make boxes.
