Recruiting studies
- NCT06231654Recruiting
Using a camera to check vital signs in children
This study tests if a special camera can measure heart rate and breathing in children without touching them. It may help make checkups easier and less stressful.
NiceAges 3–17 - NCT06536647Recruiting
Contactless vital sign check for ER triage
This trial uses a camera to measure your vital signs (like heart rate) without touching you, right in the emergency room. The goal is to see if this contactless method can help quickly assess patients when they arrive.
Hong Kong, None SelectedAges 18 years+ - NCT07719660Recruiting
Wearable blood pressure monitor comparison study
This study compares a wearable blood pressure monitor to standard measurements. It needs people whose arm can be used for a cuff and who can give consent, and some participants are in the ICU.
Dresden, SaxonyAges 21–85 - NCT07749183Recruiting
Light-based detection of atrial fibrillation in heart failure
This study tests a new device that uses light to detect irregular heartbeats (atrial fibrillation) in people with heart failure. If you join, you'll wear a small sensor that may help catch early signs of this condition.
BratislavaAges 18 years+ - NCT07548723Enrolling by invitation
Nerve Stimulation Device Reliability Study
This study tests how reliably a small ear-stimulation device measures heart-rhythm patterns. Researchers want to see if the device gives consistent readings across multiple measurement sessions, which could help doctors monitor heart health in the future.
SinopAges 18–40 - NCT07240831Recruiting
Blood pressure monitor trial for people with or without irregular heartbeat
This trial tests a small chest patch that measures blood pressure without a cuff, using a light sensor. It is designed for people who need 24-hour blood pressure monitoring, including those with atrial fibrillation or atrial flutter.
Birmingham, AlabamaAges 18 years+ - NCT04843371Recruiting
Using wearable data to predict heart pump strength
This trial tests whether a wearable device (Biostrap) can help predict how strongly your heart pumps, using echocardiogram (heart ultrasound) results. It may help doctors better estimate heart function from simpler measurements.
New Orleans, LouisianaAges 18–120 - NCT05795582Recruiting
Measuring blood flow in people with type 2 diabetes
This study tests a simple, noninvasive technique (photoplethysmography) to measure blood flow in the legs of people with type 2 diabetes. It may help doctors better detect and monitor peripheral artery disease (PAD), a condition that narrows arteries and can lead to leg pain or poor healing.
AntibesAges 18 years+ - NCT06222645Recruiting
Comparing two dyes in gastrointestinal surgery
This trial compares two dyes used during stomach or intestine surgery to see which helps surgeons see the blood flow better. It may help decide which dye works best for safe reconnections.
Yantai, ShandongAges 18 years+ - NCT06786364Recruiting
Measuring blood flow waves in sepsis patients
This study uses a special light sensor to measure blood flow waves in patients with septic shock. The goal is to see if these waves can help doctors understand how severe the shock is.
Mexico City, CuauhtemocAges 18 years+ - NCT07520344Recruiting
Testing a wearable device to measure body hydration levels
This study tests a wearable wrist device that measures hydration by sensing blood flow in your skin. Researchers will monitor how well it works when you're dehydrated on purpose, which could help develop better ways to track hydration for health and fitness.
Frisco, TexasAges 18–45

Common questions
- Are there clinical trials for photoplethysmography?
- Yes. Clin2 currently lists 11 recruiting photoplethysmography studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a photoplethysmography trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a photoplethysmography trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
