Smartwatches incorporate various sensors to enhance their functionality. Here are some of the key sensors you’ll find in our Yuuma smartwatches:
This sensor tracks your body movements by counting steps and also monitors your sleep patterns. It measures acceleration across the X, Y, and Z axes. Keep in mind that accuracy can vary depending on the quality of the wearable device.
The gyroscope measures angular velocity, going beyond linear motion detection. It helps differentiate activities (like jogging vs. running) and contributes to accurate motion tracking.
Smartwatches use optical sensors to measure your heart rate continuously. This data is valuable for fitness tracking and health insights.
- GPS (Global Positioning System):
GPS provides location information, allowing smartwatches to track your outdoor activities, navigation, and location-based services.
Some smartwatches include a barometer to measure atmospheric pressure. It helps predict weather changes and altitude tracking.
Measures blood oxygen levels, providing insights into overall health and fitness.
These sensors monitor your skin temperature, which can be useful for detecting fever or changes in body temperature.
Our Yuuma smartwatches have the ability to measure and estimate blood pressure using optical sensors, to some degree of accuracy. They are not meant to be used as a medical device or to replace one.
Blood pressure sensors work in a different way to heart rate monitoring. To accurately measure blood pressure, it is necessary to briefly stop the circulation of blood. This allows for the force required by the heart to pump blood around the body to be recorded at the time of pumping (the systolic pressure) and in between pumps (the diastolic pressure). For this to be achieved, a wrist strap that can inflate, similar to the cuff of an automatic blood pressure monitor, is required. This option would be the most accurate and reliable, but also the least convenient.
Detect Radiation Level to avoid physical damage. Detecting radiation levels is important to avoid physical damage because high levels of radiation can cause serious harm to the human body, including damage to cells and organs, and an increased risk of cancer. By monitoring and detecting radiation levels in the environment, individuals can take appropriate precautions such as leaving the area or using protective gear to minimize their exposure and reduce the risk of physical harm.
- NON INVASIVE BLOOD GLUCOSE MONITOR
Designed with advanced non-invasive technology, these smartwatches offer a seamless and painless solution for people with type 1, type 2, and gestational diabetes. They use advanced optical sensors and spectroscopy to analyze glucose levels through the skin, eliminating the traditional finger prick method.
- URIC ACID DETECTION MONITOR
Yuuma Smartwatches equipped with uric acid detection capability use specialized biosensors, such as electrochemical sensors. These sensors are designed to specifically detect and measure uric acid levels in the body.
Sample collection:
To measure uric acid, you may need to provide a small sample of your blood or other bodily fluids. Some smartwatches have built-in mechanisms for collecting these samples, while others may require the use of external accessories like test strips or cartridges.
Measurement and analysis:
The sensor in the smartwatch comes into contact with the collected sample, and it detects any chemical reactions that occur when it interacts with uric acid molecules present in the sample. These reactions generate an electrical signal that is then converted into numerical data using algorithms within the smartwatch.
Data display and tracking:
The measured uric acid level is displayed on the screen of the smartwatch in real-time or stored for later analysis on a connected smartphone app or cloud platform. This allows users to track their uric acid levels over time and observe any patterns or changesIt's important to note that while some smartwatches claim to accurately measure uric acid levels, medical-grade accuracy can only be achieved through laboratory tests conducted healthcare professionals using specialized equipment. Smartwatch-based measurements should be used as an indicative reference rather than definitive medical diagnostic tools.
- BLOOD LIPID CHANGES MONITOR
Yuuma smartwatches equipped with blood lipid monitoring capabilities typically use a combination of optical sensors, electrical sensors, and sophisticated algorithms to estimate lipid levels in the blood.
Optical Sensors:
These sensors use light to measure various properties of the blood. By emitting light into the skin and measuring the light that is reflected back, the smartwatch can gather data on blood flow and composition. Different wavelengths of light can penetrate the skin to different depths and can be used to detect various biomarkers.
Electrical Sensors:
Some smartwatches also use bioimpedance sensors, which measure the resistance of body tissues to a small electrical current. This can provide additional data on blood composition and help in estimating lipid levels.
Data Analysis:
The raw data collected by the sensors is processed using advanced algorithms. These algorithms analyze patterns and changes in the data to estimate levels of different blood lipids, such as cholesterol and triglycerides.
- ECG MEASURE (Detection of abnormal Cardiac signals)
Smartwatches equipped with ECG (electrocardiogram) capabilities monitor cardiac signals and detect abnormalities using the following key steps:
1. Electrical Sensors:
Electrodes: Smartwatches have built-in electrodes, typically located on the back of the watch and the bezel or crown. These electrodes detect electrical signals generated by the heart.
2. Data Collection:
- ECG Recording:
When the user initiates an ECG recording, they place their finger on the watch's electrode. This completes the circuit between the heart and the electrodes, allowing the watch to record the electrical activity of the heart.
- Duration:
The recording usually lasts around 30 seconds, capturing a single-lead ECG, which shows the heart's rhythm and electrical activity over that period.
3. Signal Processing:
- Waveform Analysis:
The smartwatch processes the captured electrical signals to produce an ECG waveform, displaying the different phases of the heart's electrical cycle (P-wave, QRS complex, and T-wave).
4.Abnormality Detection:
- Algorithm Analysis:
Advanced algorithms analyze the ECG waveform to detect irregularities such as atrial fibrillation (AFib), bradycardia (slow heart rate), and tachycardia (fast heart rate).
- Comparison with Norms:
The smartwatch compares the recorded data against established norms to identify potential abnormalities.
5. User Feedback:
- Results Display:
The smartwatch displays the results of the ECG analysis, indicating whether the heart rhythm is normal or if any irregularities are detected.
- Health Alerts:
If abnormalities are found, the smartwatch may prompt the user to seek medical advice and provide an option to share the ECG data with healthcare professionals.
By using these steps, smartwatches offer a convenient, non-invasive way to monitor heart health and detect potential cardiac issues in real-time.
To know your Metabolic level in different states. Your metabolism is the process by which your body converts food and oxygen into energy. During a metabolic test, you typically undergo two different assessments: resting metabolic rate (RMR) and exercise metabolic rate (EMR).
1. Resting Metabolic Rate (RMR):
This measurement determines how energy your body requires at rest. It is usually conducted in a relaxed state when you are lying down or sitting comfortably. The test measures the amount of oxygen you consume and the amount of carbon dioxide you produce to calculate the number of calories burned while at rest. TheMR reflects approximately 60-75% of your total daily energy expenditure.
2. Exercise Metabolic Rate (EMR):
This measurement determines how many calories your body burns during physical activity or exercise. EMR tests are performed while engaging in various exercises on equipment like treadmills, stationary bikes, or elliptical machines. monitoring breathing patterns and gas exchange during exercise at different intensities, it estimates how efficiently your body utilizes oxygen to generate energy.
The main purpose of these tests is to assess an individual's unique metabolism and valuable information related to weight management, nutrition planning, fitness programs, and overall health optimization.
Based on inputs such as age, weight, gender, heart rate data, and physical activity levels registered through sensors like accelerometers or gyroscopes, our Yuuma smartwatches can estimate calories burned during workouts.
- BMI - Body Mass Index Analysis
Body Mass Index (BMI) analysis via smartwatches typically involves using sensors to gather data on the user's physical activity, heart rate, and other health metrics. Here's a concise explanation of how it works:
Data Collection:
1. Accelerometers:
Measure physical activity and motion to estimate calorie expenditure and activity levels.
2. Heart Rate Monitors:
Track heart rate, which helps in estimating energy expenditure and overall fitness level.
User Input: The user manually inputs key data such as height and weight into the smartwatch or its companion app.
BMI Calculation:
The Yuuma smartwatch uses the standard BMI formula:
