MedicalResearch.com Interview with: Professor Sherry Towfighian PhD Mechanical Engineering Binghamton University   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We wanted to avoid using batteries in a load monitor that can be placed in total knee replacement. We looked into energy scavenging technologies and studied the most appropriate one for this application. Energy scavenging is converting wasted energy such as walking to electricity for low power sensors. Our research study showed walking can provide enough electrical energy (about 6 microwatts) for low power load sensors. These load sensors are important in providing information about the mechanical load throughout different activities. It can be used in the future to create a self -awareness device for the patient to avoid certain activities.  (more…)
