ME Project #3: Engineering a Synthetic Neuron Using Bottom-Up Synthetic Biology
Faculty Mentor: 
Allen Liu, allenliu@umich.edu
Project Description: Building synthetic cells is an exciting area of synthetic biology with opportunities to unravel basic design and organizational principles of cellular life. Besides a cellular reconstitution approach of using purified protein components, the current paradigm in the construction of a bottom-up synthetic cell system involves lipid bilayer vesicle encapsulation of cell-free expression systems to engineer active membranes. The Liu lab and his collaborative team have identified neuron as a potentially tractable system to construct from the bottom-up. Neurons convert biochemical information (through binding of a neurotransmitter) to electrical signal (via action potential) and back to biochemical signal (through the release of neurotransmitters). These distinct and separable processes can be reconstituted in a synthetic neuron by using natural and engineered proteins. As part of the team, the student involved will be offered an opportunity to work on reconstituting ion channels using a mammalian cell-free expression system and testing their functions using electrophysiology.

Faculty Mentor: Serife Tol, stol@umich.edu
Project Description: Metamaterials can manipulate and control the propagation of acoustic/elastic waves in ways that are not possible in conventional materials. Although metamaterials have helped to advance technology, researchers have mostly relied on linear and passive unit cells which limit their applicability. This project focuses on the exploration of active unit cells with piezoelectric materials which can be controlled externally by means of electrical loading. The theoretical framework developed from this research will form the basis for the design of tunable and adaptive structures. The results of the project can be extended to novel concepts toward enabling next-generation multifunctional wave devices (i.e. energy harvesters, sensors, mechanical lenses, mechanical filters, noise and vibration absorbers, etc.). 

Keywords: Metamaterials, piezoelectric energy harvesting, vibration/noise isolation, active unit cell, elastic wave control, adaptive structures

ME Project #10Conformal Metamaterials for Preserving and Transmitting Wave Energy
Faculty Mentor: Serife Tol, stol@umich.edu
Project Description: This project focuses on conformal metamaterials/phononic crystals for non-planar structures. One direct application of this research is the design and integration of conformal elastic lenses with pipe-like structures to enhance sensing in nondestructive testing. Hence, signals carrying the critical damage information can be preserved and transmitted over long distances without suffering from the attenuation problem. Collaborative research explores the focusing of different wave modes in long range pipelines toward increasing the signal to noise ratio of the sensors and thereby improving damage detection capability. Fluid-structure interaction will also be investigated in this research. Additive manufacturing techniques are to be incorporated in the design and experimental phases of the project.

Keywords: Conformal metamaterials, wave focusing, enhanced sensing, nondestructive testing

ME Project #11Data-Driven Balance Training: Collection and Post-Processing of Older Adult Balance Data
Faculty Mentor: Kathleen Sienko, sienko@umich.edu
Project Description: Age-related declines in balance function drastically impact quality of life and present long-term care challenges; falls are the leading cause of fatal and non-fatal injuries among older adults. Successful fall prevention programs include balance exercise regimes, designed to recover, retrain, or develop new sensorimotor strategies to facilitate functional mobility. We seek to develop an automated system for evaluating balance performance and recommending training exercises for older adults. Our approach leverages body kinematic data collected from inertial measurement units, and uses them to create data-driven models via machine learning techniques that can then accurately assess and predict patient performance. This SURE project will focus on the collection, post-processing, and preliminary analysis of older adult balance-related data in a controlled laboratory setting. The student will work together with a graduate student and/or a post-doctoral fellow to collect, post-process, and perform a preliminary analysis of inertial measurement unit, passive motion tracking, and video data.

ME Project #12: Data-Driven Balance Training: Data Analytics and Machine Learning
Faculty Mentor: Xun Huan, xhuan@umich.edu
Project Description: Age-related declines in balance function drastically impact quality of life and present long-term care challenges; falls are the leading cause of fatal and non-fatal injuries among older adults. Successful fall prevention programs include balance exercise regimes, designed to recover, retrain, or develop new sensorimotor strategies to facilitate functional mobility. We seek to develop an automated system for evaluating balance performance and recommending training exercises for older adults. Our approach leverages body kinematic data collected from inertial measurement units, and uses them to create data-driven models via machine learning techniques that can then accurately assess and predict patient performance. In particular, this SURE project will focus on the data analytics tasks. The student will work collaboratively within the team to process and manage collected datasets, explore and identify representative features, and build and validate machine learning models. Furthermore, the student will also explore the effects of uncertainty in the data and models, and analyze how it affects the prediction quantities. Experience in Python programming is a plus.

ME Project #13: Modeling Feedback Dynamics in the Arterial System
Faculty Mentor: Kenn Oldham, oldham@umich.edu
Project Description: This project will compare experimental measurements of feedback mechanisms for regulating blood pressure in the cardiovascular system with models proposed from prior literature.  The faculty mentor’s research group has recently developed wearable sensing techniques to continuously measure changes in artery behavior, such as vascular resistance and stroke volume, that have generally been difficult to monitor non-invasively.  Preliminary results from animal and human subjects suggest that there are consistent feedback dynamics observed between blood pressure fluctuations and these phenomena.   The student will evaluate whether various feedback models presented in literature are consistent with apparent experimental feedback behavior, and attempt to fit model parameters to experimental subject data.   Suggest background of dynamic systems and fluid dynamics coursework.

ME Project #14One-way Waves
Faculty Mentor: Karl Grosh, grosh@umich.edu
Project Description: In this research, new classes of highly directional acoustic waveguides are developed for transmitting acoustic waves in one direction either as part of a communication network or for absorbing waves for noise control. One goal is to produces an acoustic system were waves enter without reflection, a perfect acoustic black hole. We use mechatronic systems and modeling to achieve this goal. Our new approach is to use a network of distributed sensors whose signal is directed forward in space to an array of actuators located in a distributed fashion further down the waveguide. When the energy carried by an acoustic wave is fed forward in a unidirectional fashion via a distributed amplifier network, a preferential direction is created because the information (energy) is nearly instantaneously transmitted in only one direction by the electronics, while fluidic or structural disturbances propagate at the group velocity of the waveguide. This distributed, local control enables us to dramatically alter the wave propagation (we’ve essentially created an artificial wind to transport energy in one direction). We have had great success in working toward this goal and look to continue this through this summer SURE program. The summer research will involve electronics, acoustics, and vibration along with fabricating electro-mechanical systems.

ME Project #15: Connected Testbeds for Connected Automated Vehicles
Faculty Mentor: 
Tulga Ersal, tersal@umich.edu
Project Description: Connected testbeds, i.e., remotely accessible testbeds integrated over a network in closed loop, will provide an affordable, repeatable, scalable, and high-fidelity solution for early cyber-physical evaluation of connected automated vehicle (CAV) technologies. Engineering testbeds are critical for empirical validation of new concepts and transitioning new theory to practice. However, the high cost of establishing new testbeds or scaling the existing ones up hinders their wide utilization. Enabling high-fidelity cyber-integration of existing but geographically dispersed testbeds can dramatically increase accessibility to engineering experimentation, just as the internet dramatically increased accessibility to information. This project aims to develop a scientific foundation to support this vision and demonstrate its utility for developing CAV technologies.

ME Project #16: Motion of Water Droplets on Lubricated Surfaces
Faculty Mentor: Solomon Adera, sadera@umich.edu
Project Description: Controlling the motion of droplets on solid surfaces has broad technological implications ranging from microfluidics to thermal management. Past approaches utilized gradients in topography, temperature, chemical composition, surface tension or a combination thereof to manipulate droplets on solid surfaces. In this study, we utilize asymmetry of the wetting ridge to trigger motion of water droplets on lubricated surfaces. Specifically, we will investigate the motion (directionality and speed) of droplets on micro/nanoengineered surfaces. Additionally, we will investigate the criteria and time scale for coalescence. The results of this study will aid the rational design of lubricated surfaces for various engineering applications.

ME Project #17: Millimeter-size Bump Optimization for Fog/Water Harvesting
Faculty Mentor: Solomon Adera, sadera@umich.edu
Project Description: Inspired by the Namib desert beetle, millimeter-size bumps have been demonstrated to enhance fog/water harvesting by directing vapor transport towards the apex of the bump. Experimental results have shown a 6x increase in water collection at the apex of a bump (due to higher vapor concentration gradient) when compared to the flat base. This work, which involves both experiment and modeling, is aimed at optimizing the size (diameter and spacing) of the bumps to maximize fog/water harvesting.
