Although medical doctors and engineers generally work in completely different domains, there's a fair amount of overlap between the disciplines. At the end of the day, they both solve problems, and while doctors clearly focus on the biological aspects of disease, there just might come a point where the problem has to be addressed with engineering principles. From the intricate design of an artificial hip to the electrical interface between an amputee's nervous system and a prosthetic limb, biomedical engineers can make a tremendous contribution to positive patient outcomes. 

Nyeli Kratz, a recent biomedical engineering grad, has worked on quite a few engineering solutions to diseases. Many of her projects, like this stand-up mobility aid or a wheelchair attachment that lets a tetraplegic father interact with his newborn child, seem aimed at making it easier for patients to interact with the world. She'll stop by the Hack Chat to talk about these projects in particular as well as what the engineer brings to the table when it's time to design hardware that heals.

    OK, welcome everyone, let's get started. I'm Dan, I'll be modding today along with Dusan as we welcome Nyeli Kratz to the Hack Chat. Today we're talking about biomedical engineering.

    Hello and welcome everyone!
    Dan Maloney  3:01 PM
    Hi Nyeli! Can you kick things off with a little about yourself?
    Dan Maloney  3:02 PM
    @chordophony - Nope, just a text chat, AMA style
    Nyeli Kratz  3:02 PM
    Hi I'm Nyeli! I'm a recent grad from Johns Hopkins University and I studied biomedical engineering and robotics. BME is definitely a broad topic but I'm happy to chat about any of my projects! Some of my favorites are a one-arm-drive standing mobility device for pediatric hemiplegia patients and a wheelchair attachment for a tetraplegic new dad.

    Gotta admit I'm surprised we haven't had anyone in BME on before. I nearly went that way as an undergrad, but, you know, math...
    Walter Lite  3:03 PM
    nice work
    Nyeli Kratz  3:05 PM
    Thank you! BME was an awesome major for undergrad since it gave me a lot of opportunities to apply my technical skills to solve meaningful problems
    Walter Lite  3:05 PM
    are you presenting at RESNA this year ?
    shahmalekim  3:06 PM
    Nice Work Nyeli, is there a plan to add AI to the Agile Stand in future roadmap?
    rothemike  3:06 PM
    Hi there, I became a new quadriplegic on October 14, 2023. I would love to hear more about your wheelchair attachment if possible. Thanks for doing what you do
    Walter Lite  3:06 PM
    I spent over 20 years in Cinica and rehab engineering ....

    I am Biomedical engineer and have been focusing on Cybersecurity of medical devices (IoMT) for the past 5 years.
    Thomas Shaddack  3:07 PM
    Is there any standard for such attachments? T-slots? Spaced arrays of holes? NATO rails...?
    Dan Maloney  3:07 PM
    So going back to the comment about BME being a broad topic, seems like there needs to be a mix of ME, EE, and even CE involved in a lot of these projects. Do people come into BME with a sort of "concentration" in mind? Or does everyone sort of have to be a generalist?
    Nyeli Kratz  3:08 PM
    Hi @rothemike this was my wheelchair attachment project. Josh Basile is super awesome. He came to us a few months before his baby was due looking for help designing an attachment to his wheelchair to allow him to spend more time one on one with his newborn and this is what we came up with.
    Walter Lite  3:08 PM
    you have to believe that you can make a difference
    chordophony  3:08 PM
    hi Nyeli, those projects look awesome, and it must be great to work on something that can really help people! my daughter is studying BME, and I'm curious about the types of jobs you've found out there where you can work on projects like those? can anyone else offer advice or resources about BME careers?
    Nyeli Kratz  3:10 PM
    At Hopkins we all have concentrations within the major. Mine was imaging and medical devices which is still pretty broad. People can definitely specialize within BME @Dan Maloney. Some other students chose to focus on data science or more on the biology immunoengineering or neuroengineering side
    Walter Lite  3:10 PM
    and ....... try to get funding for your projects
    shahmalekim  3:10 PM
    @Dan Maloney , good question, as far as I know people get into biomedical engineering with different backgrounds and in Masters and PhD you can normally pick a stream...

### Biomedical Engineering and Nyeli Kratz's Contributions

Medical doctors and engineers often overlap in problem-solving, especially in biomedical engineering. While doctors focus on biological issues, engineers bring technical solutions to medical problems.

#### Role of Biomedical Engineers

Biomedical engineers design medical devices and systems to improve patient outcomes, such as:
- **Artificial Hip Joints:** Restoring mobility.
- **Prosthetic Limbs:** Providing functionality to amputees through nervous system interfaces.

#### Nyeli Kratz's Work

Nyeli Kratz, a recent biomedical engineering graduate, has developed innovative solutions, including:
- **Stand-Up Mobility Aid:** Helping individuals stand up independently.
- **Wheelchair Attachment:** Enabling tetraplegic fathers to interact with their newborns.

#### Upcoming Hack Chat

Nyeli will discuss her projects and the role of engineers in medical device design, focusing on hardware that aids healing and patient interaction.

I'd like to know how you find do-it-yourself assistive technology and devices, where you get help to produce, improve and use? Many disparate sites are out there, from thingiverse to many fablab sites. Has anybody thought of unifying them with some aggregator? Where do BME get their inspirations?
