Bed Sore Sensors: PCBs and Enclosures

I spent the week 3D printing these enclosures for the bed sensor electronics and LCD display. Sleeping in one position too long causes bedsores due to extended applied pressure on local vasculature. We hope this device can be developed to… Continue Reading →

Device for the Improvement of Neuronal Feedback: Sub-Threshold Tactors

This is a quick instructional video our research associate, Henry Do, made to help doctor of physical therapy (DPT) students learn about the device they’ll be using for data collection for their capstone studies. Good luck you guys!

Exploring Servo Motors for use in Rehab Engineering

Learning electronics is a test of patience. Plenty of reading and plenty of tinkering. Our team is constantly adding new technologies and skills to our tool belt. Here is a comedic video of our lab research associate, Henry Do, stumbling… Continue Reading →

Building a Platform for the GRAIL

Chris Hoang is a whiz at constructing things. He built this removable platform for our GRAIL system for an upcoming study (more on this soon). When designing the platform, Chris had to consider the multiple factors from material properties to… Continue Reading →

Video: Basic Introduction to Our Prototype Shoe Sensors

Sticky post

This is a prototype shoe (v2) I helped design and build. It was designed for children suffering from habitual toe-walking, which can lead shortened Achilles tendon. Since the behavior is often due to an unconscious habit, it’s function make patient’s… Continue Reading →

Here’s my colleague Chris Hoang explaining how we start to approach biomechanical data processing! For more check out my Instagram: @henrydodesign

Hi Everyone, the Motion Capture Lab is where I do some of my research. My current interests centers around gait analysis and fall risk assessment. #biomechanics #motioncapture

Let’s Welcome Chris Hoang to the GRAIL Lab!

Chris Hoang is a wonderful new addition to our lab. His unique blend of skills from healthcare volunteering, CAD design, and mechanical aptitude will prove extremely useful for designing and constructing experimental devices for our lab.

Presenting our research | Crean College of Health and Behavioral Sciences

Here is Henry Do (above) and Michael Pollind (above) presenting their research on the use of wearable sensors in fall risk assessment in older adults. Here is Sharon Kim presenting her work with machine learning/deep learning algorithms and idiopathic toe-walking in… Continue Reading →

Human Factors Engineering: Making Shoes for Data Collection that Integrate Fashion and Technology

Passion drives persistence! (1) Stochastic Resonance Wearable (2) Gait/Postural Stability Insole Sensor (3) Ideopathic Toe-Walk Rehabilitation Shoe View this post on Instagram Soldering is overrated. When fixing broken wire connections, the most time and effort efficient method is to through… Continue Reading →

Our Lab Prides Itself on Designing Original Circuits and Software for Our Motion Sensors

This is the smallest motion sensor our lab has achieved. We’ve swapped out our prototyping parts for smaller high-end components and shrank the board to the size of a penny. We’ve improved power efficiency by including idle period protocols in… Continue Reading →

Bed Sensor Enclosure Design

Motion Sensor Prototype (coin size)- Acryllic Glass cover to enable visual feedback capacity, battery and SD card ports, and chamfered corners to improve comfort from wearing. #fusion360 #pcbenclosure  Motion Sensor Enclosure developed using parametric modeling. I am not a big fan of… Continue Reading →

Biomechanics is Interdisciplinary and All Our Projects are Thanks to Our Wide-Skill Sets

This is the smallest motion sensor our lab has achieved. We’ve swapped out our prototyping parts for smaller high-end components and shrank the board to the size of a penny. We’ve improved power efficiency by including idle period protocols in… Continue Reading →

Developing a Mobile App to Improve Data Collection Efficiency from Arduino-Based Accelerometers

  I’m taking a mobile app development course online and made this prototype app. I’m just working on the user interface and visual display, but I made this barebones prototype to illustrate its core function: data collection. I want to… Continue Reading →

Our Lab’s New Driving Simulator Will Bring Fresh Projects to Rehabilitate Our Stroke Patients

We’re getting trained right now on a new driving simulator. We’re going to use it for driving and neurorehabilitstion research on stroke patients. Lots of kinematic data processing in Matlab awaits in the future. Love my field.
