Researchers led by Professor William Kaiser have invented a novel wireless, passive, and biocompatible sensor that can sense flow in bronchoscopically implanted stents in situ and in the absences of specialized equipment. This invention can be used as a straightforward electromechanical upgrade to current stent fabrication methods and can be used in place of current stents. This technology offers a safe and convenient method for effectively guiding COPD rehabilitation and treatment that has not been previously available and could potentially be used for other biosensing applications, such as orthopedic and dental implants as well as wearable fabrics (i.e. smart patches).

State Of Development Wireless sensor system development confirms feasibility Background Chronic obstructive pulmonary disease (COPD) is a progressive and debilitating disease affecting between 10-24 million adults in the U.S. alone, and is expected to become the third most common cause of death worldwide within the next decade. Routine visits are necessary for patients after undergoing lung volume reduction surgery to monitor for changes in pulmonary function and complications, but real time changes in lung function can be missed during these visits. The addition of sensor technology to stents has the potential to transform the treatment for emphysema, as it will decrease the risk of delay in determining complications and provide on-demand feedback without a visit to the clinic.
