- Design and 3D printing of a focused ultrasound lens to provide differential tissue heating to effect targeted drug release during pediatric cancer treatment. Certain chemo drugs cause heart damage in children when delivered in effective cancer treatment doses. By coating the drug in a temperature-sensitive wax and gently heating the tumor with focused ultrasound, the system dose can be kept to safe levels while still treating the cancerous region with a full dose.
- Development of a process to use MRI images to extract a model of the prostate and then 3D print a mold from this model to fix the prostate for pathology processing and examination.
- Software development of a neuro triage device application to analyze eye tracking and response data to detect head trauma.
- Design and prototype of low noise, miniaturized (3cmx2cm) interface board to support electroneuromodulator impedance spectroscopy studies on rodents.
- Development of prototype electronic hardware (MCU, power management, analog circuits), 3D mechanical design, signal processing algorithms, and system software for an industry sponsor in support of product development.
- Support of brain research at the UT Dallas Center for BrainHealth with the development of a flexible multifunctional system for transcranial electrical stimulation. Current systems are limited in their single electrical signal modes, number of nodes, measurement and programing. The new system will have multiple electrical signal modes, an expanded number of nodes, enhanced measurement capabilities and easier programming. Possible applications include PTSD treatment, memory enhancement and coma treatment.
- Prototype of a device to provide ophthalmic surgeons with low cost, disposable, hands-free illumination of the internal structure of the eye during surgery.
- Design and prototype of a microcontroller-based control and recording system integrated with LED illumination embedded in an eyeglasses-type frame. Device supports experimentation in the treatment of long nerve demyelination using optic nerve stimulation.
Dr. Robert Gregg, assistant professor of bioengineering and mechanical engineering, is developing powered prosthetics that apply robot control theory to dynamically respond to the wearer’s environment, enabling amputees to walk with the confidence and ease of natural locomotion.
Dr. Gregg’s lab focuses on the development of the algorithms controlling the prosthetics, while the Applied Research Center engineering team applies their knowledge and experience to build the devices, developing several generations of prosthetic legs to support implementation and testing of the control algorithms.
