Dr. Meyer directs the Experimental Biomechanics Laboratory (EBL) at Lawrence Technological University with the goal to advance experimental biomechanics understanding by providing practical training to engineering and medical students and advancing the boundary of knowledge through translational research. The EBL enthusiastically cultivates collaborations with clinicians and the medical device industry to develop preventative and regenerative treatments for bone and soft tissue damage and disease. Recently, the EBL has partnered with ME and EE faculty to develop a ”Biorobotics/Haptics” facility that provides practical, hands-on experiences to students focused around the topics of sensing, perception, and control in next generation robotics.
Funding for the EBL equipment, supplies and personnel come from a variety of sources including; internal support from LTU, foundation grants, in kind donations from industry, and contract research project with industry partners. The EBL has supported LTU’s efforts for increased partnership with local hospitals such as Beaumont, Detroit Medical Center, Henry Ford and Providence. These projects are currently being developed in the areas of oral and orthopaedic surgery, sports medicine, simulations, radiology and robotic surgery. The EBL has trained/supervised more than 20 undergraduate student research projects, 11 BME senior projects, and 3 graduate student research projects.
Human Participant Testing Equipment
- A new Biomechanics Laboratory (1300 sq. ft.) was custom designed as part of the 2016 Taubman Complex building.
- Vicon three dimensional (3D) optical motion analysis system for gait analysis, biomechanical tissue testing, and 3D computer generated animation, including 10 Bonita cameras, and a Basler high speed reference video camera, with Nexus, Polygon and Plug In Gait software.
- Two Kistler portable, multicomponent, force platforms with built-in amplifiers and external control units to specify the operating sensitivity/maximum force level. The forceplates are digitized by the Vicon system to determine the relevant Ground Reaction Force (GRF) vectors needed for the analysis of human movement.
- Delsys® Trigno 16-channel, wireless sensor system with a variety of physiological monitoring sensors, including; surface electromyography (EMG), 3-axis accelerometers and/or, electrocardiography (EKG) electrodes. The wireless capability allows the muscle’s action potential and body segment’s movement data to be transmitted (over 100 ft) to the base station using a 2.4 GHz RF communication protocol. The digital data is transferred via USB to the computer and then recorded and analysed with Delsys EMGworks software. Or alternatively, the EMG voltage can be synced through the Vicon system to simultaneously record the 3D motions, GRF and EMG simultaneously during a human biomechanics experiment.

- Wii Balance Board uses Bluetooth technology and contains four pressure sensors that measure the user’s center of balance and vertical ground reaction force.
- Leap Motion controller is a small USB peripheral device which is designed to be placed on a physical desktop, facing upward. Using two monochromatic IR cameras and three infrared LEDs, the device observes a distance of about 1 meter. Markerless motion videos at 300 frames per second are analyzed to determine 3D position data of the hands. A user can perform computer interface tasks such as navigating a website, using pinch-to-zoom gestures on maps, high-precision drawing, and manipulating complex 3D data visualizations.
- Nike+ Shoe Sensor Kits consist of 2 insole devices each containing a 3-axis accelerometers and flexible electronics consisting of 4 pressure sensors and a fixture to hold a puck (rechargeable power and controller that connects the sensors and transmits data over Bluetooth). There are also iOS apps for wirelessly receiving and displaying sensor information.
- Myo gesture control armband reads the muscle activity in your forearm and gives you touch-free control of technology with hand gestures and motion. Out of the box, the Myo armband detects five distinct hand gestures and motion to wirelessly control technology. The Myo armband uses Bluetooth Smart to connect to Mac, Windows, iOS, and Android devices.
- Triax Smart Impact Monitor is a lightweight, impact sensing and reporting device, intended for using during sports activities where there is a possibility of head impact injury. The device may be comfortably worn during sports activities using either a headband or skullcap style holder. It will record all impacts and accelerations greater than a pre-programmed set-point. All measurements are transmitted in real time to a nearby base monitoring unit using a low power wireless link.
- NeuroSky MindWave safely measures and outputs the EEG power spectrums (alpha waves, beta waves, etc), eSense meters (attention and meditation) and eye blinks. The device consists of a headset, an ear-clip, and a sensor arm. It can be used with a wide variety of games, braintraining, education, and other brain-computer interface applications.
