Frequently asked questions
How does the SleepSense sensor detect snoring?
The SleepSense Piezo Snore Sensor utilizes advanced Piezo-electric technology to accurately detect snoring events during diagnostic sleep studies. The mechanism works as follows:
- Vibration Conversion: An internal Piezo crystal captures the mechanical vibrations transmitted through the patient’s neck tissue, which are generated by snoring.
- Signal Output: This mechanical energy is immediately converted into a small, measurable analog voltage signal (typically aiming for 1 mV peak to peak).
The sensor is engineered for optimal signal stability. Its integrated small bump maintains constant skin contact to ensure artifact resistance against movement or sweating, and it is built with high noise immunity for clean signal acquisition in clinical settings.
Which professional sleep study systems are compatible?
The SleepSense Piezo Snore Sensor is highly versatile for professional diagnostic use, connecting via a 1.5 mm touch-proof connector to an AC jack box (no batteries are required).
It is compatible with various monitoring equipment from leading polysomnography manufacturers, including:
- Carefusion: SensorMedics Viasys, Somnostar z4
- Cadwell: Easy III
- CompuMedics: Grael HD PSG, Somte, E Series
- Natus: Sandman 32, Sandman 20, Xltek, Biologic, Grass, Stellate
- Nihon Kohden: Polysmith
- NeuroVirtual: BWII PSG, BWIII PSG/EEG
Is this snore sensor battery-free?
Yes, this snore sensor is battery-free. The SleepSense Piezo Snore Sensor operates passively, meaning it requires no external power source or batteries. It connects directly to a compatible AC jack box using the integrated 6’4” cable and 1.5 mm touch-proof connector.
What are the typical polygraph settings?
The SleepSense Piezo Snore Sensor is engineered for specialized diagnostic purposes and operates within defined parameters. The typical polygraph settings used are:
- Sensitivity: 20 to 75 µ/mm
- Low Frequency Filter: 10 Hz
- High Frequency Filter: 100 Hz
The typical output signal produced is 1 mV peak to peak, although the actual amplitude can fluctuate based on the patient’s snoring magnitude, neck density, position, and the specific polygraph equipment used.
What is the purpose of the sensor's bump feature?
The SleepSense sensor includes a small internal bump (or protrusion) as a critical part of its Consistent Contact Design.
This feature ensures:
- Continuous, reliable contact with the patient’s skin throughout the monitoring period.
- Enhanced signal stability, even if the patient moves or perspires.
- Mitigation of signal artifacts, which is essential for accurate diagnostic results from the Piezo-electric crystal technology.
Is the snore sensor immune to ambient noise?
Yes, the SleepSense Piezo Snore Sensor is specifically engineered for complete immunity to ambient noise interference.
This crucial feature ensures the sensor focuses purely on physical vibrations transmitted through the patient’s neck, guaranteeing a clear and reliable analog voltage signal for accurate diagnostic snoring detection without external acoustic contamination.
What is the cable length of the SleepSense Piezo Snore Sensor?
The sensor cable length is 6’4” and it has a 1.5 mm touch-proof connector.
Is this Piezo snore sensor strictly for professional use?
Yes, the SleepSense Piezo Snore Sensor is strictly for professional use only.
This device is intended solely for specialized diagnostic purposes in clinical settings, such as performing polysomnography (PSG) studies.
- It is not designed to function as an apnea monitor.
- Due to its professional nature, it is restricted for sale by or on the order of a physician only.
How much does the snore sensor weigh?
The SleepSense Piezo Snore Sensor is intentionally designed to be lightweight to maximize patient comfort and ensure consistent signal acquisition during a sleep study (PSG).
It weighs 2.15 oz.
This minimal weight, along with its smooth contours and high-friction material, helps keep the sensor securely in place, minimizing movement artifacts.
Is the snore sensor highly sensitive?
Yes, the SleepSense Piezo Snore Sensor is engineered for very good sensitivity and highly reliable diagnostic performance in sleep studies.
Key features supporting its sensitivity and signal quality include:
- Piezo-electric Crystal Technology: It utilizes a Piezo crystal to directly convert mechanical vibrations from snoring into a clear, measurable analog voltage signal.
- Typical Sensitivity Range: Under standard polygraph settings, the sensor exhibits a high typical sensitivity range of 20 to 75 $\mu$/mm.
- Artifact Reduction: A key design element is a small integrated bump that ensures constant skin contact, even with patient movement or sweat, minimizing signal shifting and artifacts.
- Noise Immunity: The sensor is specifically designed to be completely immune to ambient noise, ensuring that the signal represents only the patient’s snoring vibrations.
