Smartphone-based Ultrasonic Respiratory Evaluation

05314

University of Pittsburgh researchers have developed a novel, smartphone-based tool that leverages ultrasonic technology to evaluate respiratory function.

The "Smartphone-based Ultrasonic Respiratory Evaluation (SURe)" uses the existing hardware in smartphones—specifically the speaker and microphone—to provide accurate, convenient, and non-invasive pulmonary function measurements.

The present invention relates to systems and methods for pulmonary function testing, and, in particular, to systems and methods for estimating lung function, calculating airway mechanics and/or detecting airway obstructions using an electronic apparatus, such as a smartphone or similar device.

Integrated AI and Sensing System for Pulmonary Disease Evaluation

06395

University of Pittsburgh researchers have developed system techniques integrating artificial intelligence (AI) and smartphone sensing, namely PTEase, that can be used as a pulmonary telemedicine device by patients to accurately evaluate pulmonary disease conditions and provide clinically relevant information out of clinic.

Using only a commercial smartphone and a 3D-printed attachment with this novel multi-task machine learning (ML) model, it is possible to assess airway measurements from PTEase, extract appropriate biomarkers and determine key clinical information including the probability of disease and lung function indices.

There are existing pulmonary function tests, but these require specialist equipment, are costly (e.g., spirometry can cost >$50,000) and are aerosol-generating, so not suitable during a highly infectious respiratory pandemic.

Novel use of Goubau Waves in Passive Sensing

06116

These waves can travel large distances compared to free space propagation and collect data from sensors to monitor structural or environmental parameters in real time with secure data transfer, overcoming the shortfalls of existing technology.

These low loss, single line guided surface electromagnetic (EM) waves could be used to deliver wireless power to passive sensors over long distances and securely transmit collected data back to monitoring equipment.

However, they have several disadvantages including a short communication range due to rapid EM attenuation in free space, making them unsuitable for use in large systems or underground structures like well-bores or pipelines.
