Mitra Hartmann

Mitra Hartmann is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mitra Hartmann rather than just read about it. In short: Mitra J.Z. Hartmann is a professor of mechanical engineering and biomedical engineering at the Robert R.

Key takeaways

Mitra Hartmann belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mitra Hartmann to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mitra Hartmann from memory before moving on to harder problems.

Reference excerpt

Mitra J.Z. Hartmann is a professor of mechanical engineering and biomedical engineering at the Robert R. McCormick School of Engineering and Applied Science at Northwestern University. She specializes in robotics, sensory acquisition behaviors, sensorimotor integration, and neuroethology. Her lab focuses on understanding sensory signals produced by whiskers and applying similar principles to robotics.

Career Hartmann earned a B.S. in applied and engineering physics at Cornell University and a PhD in integrative neuroscience from the California Institute of Technology (Caltech). She was a computational neurobiology postdoc at Caltech and a bio-computing postdoc at the Jet Propulsion Lab. She joined the faculty at Northwestern in 2003 and won the McCormick School of Engineering Teacher of the Year Award in 2009, 2010, and 2011. She became an American Institute for Medical and Biological Engineering Fellow in 2017 and is an editorial board member for the Journal of Neurophysiology, a programming committee member for the Barrels Society, and a National Institutes of Health SMI study section member.

Research

Hartmann focuses on animal whiskers and how information about touch is sent from the whisker to the brain, and whether similar techniques could be applied to robots. In July 2017, she and her team authored a paper analyzing how artificial whiskers could be added to robots, allowing them to map their environment by touch rather than sight. This is multi-disciplinary research and her lab is made up of neuroscientists, mechanical engineers, biomedical engineers, and civil engineers, among others. In April 2021, she published a paper in PLOS Computational Biology about how whiskers bend in an S shape when whisking and signals are transmitted from the base of the follicle, activated when the whisker is pushed against it, to the brain. This research may eventually be able to be applied to helping people with brain injuries or who have suffered from strokes regain the ability to walk. She currently holds four patents:

Sensing device with whisker elements (US 7,774,951, 2010) Object profile sensing (US 8,109,007, 2012) Sensing device with whisker elements (US 8,448,514, 2013) Systems, methods, and apparatus for reconstruction of 3-D object morphology, position, orientation and texture using an array of tactile sensors (US 8,504,500, 2013)

Worked examples

Example 1 — a first encounter with Mitra Hartmann

Start with the simplest possible case. Write down what Mitra Hartmann claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mitra Hartmann before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mitra Hartmann ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mitra Hartmann

In research: Mitra Hartmann appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mitra Hartmann in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mitra Hartmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women, American biomedical engineers, American mechanical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Mitra Hartmann outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
