Smart-knee implants may soon occur, according to a study conducted at the University of Binghamton, New York State University faculty.
Knee replacement surgery is the most common replacement procedure, with the number of surgeries that grow annually. Many of these surgeries are supplanted to replace older or extinct implants. Increasingly, the dilemma is a surgery that is becoming younger and more active in patients. When they take surgery, they will remain physically active in general health, but this activity may once again be an implant. Often doctors do not know until their patients begin to develop their symptoms. Thereafter, the damage to the implant has already been done. In the case of young patients, knee replacement surgery is a tough job for five or ten years, but the level of activity to maintain the integrity of the implant has been optimal.
The researchers decided that they were able to create smart knee implants to control the changes that occurred in the activity. Assistant professor at Binghamton University, Assistant Professor, has been CEO of the National Institute of Health (NIH).
"We are working on a knee implant, monitoring how much pressure is being monitored by the sensor, so doctors can understand incomprehensible when this activity affects the negative impact," said Towfighian.
The sensors allow patients to give patients an excessive amount of time to implant a movement, to prevent and impede patients more damage to the implant. It allows you to find the sweet activity of each patient.
While the sensors resolved a problem, they brought another one. The researchers did not want the electrical sensors to have the battery required periodically, so they were able to achieve the smart goal of the implant. Instead, they worked on the energy harvesting mechanism to implement the knee implant through motion. Wathiq Ibrahim, a postdocer of the Towfighian group, developed and tested the energy collector's prototype under a mechanical machine, according to the equivalent body load to analyze its output.
They used a triboelectric energy, the type of energy that the friction receives. Every time someone goes through, the friction of the micro-surfaces binds each other to release the charging sensors.
The head teacher Emre Salman, from Stony Brook University, designed the circuit and needed 4.6 microwatts. Early studies have produced an average person's route in six micro power units, more than just enough sensing. This part of the research was complemented by Assistant Professor Ryan Willing from the University of Western Ontario, who worked on the implant design and sensor package.
These intelligent implants will not be given by doctors, but researchers will help develop future implants. "The sensors know more about the demands they put on implants, and with this knowledge, researchers can even increase implants," said Towfighian.
The hope of Towfighian is to extend the life of the knee implants and reduce the need for follow-up queries for activity sensors and self-powered systems. Young patients receive replacement surgery from generation to generation, this development is a potential for change of life.
