Chest-mounted piezoelectric sensor to help detect pneumonia early in hospitalized stroke and dialysis patients
Evaluating the Feasibility of a Piezoelectric Smart Sensor as an Aid to Help Clinicians Screen for the Development of Pneumonia in an At-risk Population
We will try a small chest sensor to see if it helps clinicians detect pneumonia earlier in hospitalized adults who have had a stroke or are on dialysis.

What this trial studies
This proof-of-concept study will enroll 70 hospitalized adults with either imaging-confirmed acute stroke or end-stage renal failure on hemodialysis at National University Hospital, Singapore. A piezoelectric sensor will be applied to six points on the posterior chest once daily (excluding weekends, public holidays, and discharge day) for up to two weeks while patients are warded. If the sensor or treating clinician detects abnormal chest sounds, a chest x-ray and other investigations will be performed according to clinical practice. The study will assess feasibility of using the sensor as an aid to screen for pneumonia and inform potential wider use in settings such as nursing homes or community care facilities.
Who should consider this trial
Good fit: Hospitalized adults aged 21 or older with imaging-confirmed acute stroke or end-stage renal failure on hemodialysis who are mentally competent to give informed consent are ideal candidates.
Not a fit: People younger than 21, those unable to give informed consent, those with active dermatological conditions, or patients not hospitalized at the study site are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the sensor could help clinicians detect pneumonia earlier in at-risk hospitalized patients, enabling faster diagnosis and treatment and potentially improving outcomes.
How similar studies have performed: Similar acoustic or sensor-based lung monitoring has been piloted in small studies, but routine use for pneumonia screening remains largely unproven.
