Acoustic Engineers use Carbon Nanotubes
Our students and faculty know what tomorrow needs. Acoustics engineering focuses on making spaces sound the best they can by analyzing complex sound waves, testing new materials, and building sound-cancelling devices. That matters because in places like hospitals, noisy heating and cooling units affect people’s ability to recover from illness and prevent airborne infection.

Research in the Human-Interactive Robotics (HIRo) Laboratory focuses on the development of lower-extremity assistive and rehabilitation devices for enhanced agility and improved mobility. Our goal in the HIRoLab is to further the critical understanding of the dynamics of gait, especially during different maneuvers, through experiments with human subjects and mathematical modeling. The lab measures approximately 1,000 square feet.
Major Lab Equipment
The lab is equipped with an Anklebot, a wearable therapeutic robot (by Interactive Motion Technologies Inc.). In addition to its intended use for rehabilitation, the Anklebot is used for studies on the estimation of mechanical impedance of the human ankle.
Bagnoli Desktop EMG Systems
This system supports eight channels for monitoring surface EMG signals and other biological signals. The system includes surface EMG sensors, force sensors, foot switches, goniometers, and EMGworks software with signal acquisition and signal-analysis modules to record and analyze both EMG and auxiliary signals.
Delsys Wireless Trigno system
This is an eight-channel, wireless, surface EMG measurement system with built-in accelerometers. The device is employed in experiments that measure the leg’s muscle activities, identify the heel strike, and lower leg accelerations during the gait.
Real-Time Camera system
The lab is equipped with an Optitrack high-speed camera system. The system consists of eight Prime 17W cameras with a low latency of 2.8 ms during wireless communications. This system is used for gait analysis and to monitor and analyze the interaction kinematics of the ankle-foot prostheses in different evaluation platforms.
The lab has a multicomponent Kistler 9281E force plate with a wide measuring range of –10 kN to 20 kN and a natural frequency of 1000 Hz. It is used for measuring the ground-reaction forces in the gait experiments.

Heavy-duty Diesel Engine Lab
The Heavy-Duty Diesel (HDD) Engine Lab is the experimental facility supporting the Diesel Aftertreatment Research Consortium and other industry- and federal-funded research. The lab features a dual-ended 500 hp dynamometer with two state-of-the-art diesel engines with full control of engine and dynamometer operation including transient cycles. Emissions of gaseous and particulate matter concentrations provide the detailed data for characterization of aftertreatment components, dosing for particulate matter oxidation, and SCR NOx reduction. High-output electrical heaters provide precise control of exhaust gas temperature separate from engine operation. Procedures have been developed for diesel oxidation catalyst (DOC), catalyzed particulate filter (CPF), and selective catalytic reduction (SCR) component evaluation. Results from the experimental work support the development and validation of detailed and reduced order models and estimators and prototype sensors.

The focus of the Ion Space Propulsion Lab (Isp Lab) is to develop and study next-generation thruster systems that use electrical energy to propel spacecraft. Electromagnetic forces are used to manipulate and exhaust ionized gases, producing reactive forces on in-space vehicles. The so-called “plasma thrusters” can only operate in the vacuum of space, so the Isp Lab maintains large, space-simulation chambers that enable ground-based testing of full-scale flight systems.
Current projects include xenon and magnesium Hall-effect thrusters that are used to raise the orbits of geostationary communications satellites, arcjets that are used to maintain orbits against gravitational perturbations, and electrospray microthrusters that are used to maneuver cell-phone-sized nanosatellites.

Micromechanical Applications and Processes Lab
The Micromechanical Applications and Processes Lab is part of the Multi-Scale Technologies Institute at Michigan Tech. In this lab, scientists research components and systems that use features and phenomena spanning dimensional scales, from nanometers to millimeters. The lab uses a precision micromilling machine that is capable of machining with 1–2-micrometer tolerances and has used tools less than 25 micrometers in diameter, or approximately one-quarter the diameter of a human hair.
Metrology is conducted for surface roughness at the nanometer scale; optical surfaces can be fabricated with natural-diamond cutting tools; and a single layer of opto-electric proteins or other biomolecules can be deposited onto surfaces for bio-solar cells and biosensors, for example.
Recent research includes modifying the surface of orthopedic implants, which results in nanoscale features for enhanced bone bonding and antibacterial properties; developing nanoscale biomolecular strain gauges for shock measurement; and separating and sensing potential disease biomarkers using microfluidic methods.

A nanoindenter is a low-load indentation system for acquiring mechanical characterization data at the submicron scale. A diamond tip is used for the indentation. Given the known geometry of the diamond indenter tip, the depth of an indentation yields the area of contact between the tip and material being indented. Making an indentation with a controlled force, while continuously monitoring the displacement of the indenter, produces data from which hardness, modulus of elasticity, fracture behavior, and other mechanical properties can be calculated. The Nanoindentation Lab houses the Agilent NanoIndenter XPS system with the following options:
- Continuous Stiffness Measurement
- Lateral Force Measurement
- High-Load System
- High-Performance Table
- Dynamic Contact Module
- Nanopositioning Stage and Nano-Vision Microscope
