Yes, they both measure skin information, but in different ways. An optical sensor measures moisture, oil, and wrinkles by reflecting light and analyzi…

Absolutely! Something like L’Oréal My Skin Track UV monitors the UV index, humidity, temperature, and even fine dust in real time, and sends a smartph…

That’s right. These days, devices don’t just measure skin conditions; they connect to AI to check pores, moisture, and wrinkles, and even recommend sk…

That’s why wearables these days have multiple microphones to detect direction. This is used to emphasize sounds from a specific direction or to elimin…

That’s right! It can analyze even the most subtle sounds from the body, so it can be used to track heartbeats and breathing. Of course, the higher the…

Ah, at its core, you can think of it as a MEMS microphone. A tiny diaphragm reacts to sound and converts it into an electrical signal. It doesn’t end …

Exactly! It’s designed to fit snugly around the wrist or forearm, minimizing sensor displacement or shaking. It then integrates all data using sensor …

It’s a little different. During exercise, the sampling rate is increased for precise measurements, and during sleep, it’s lowered to conserve battery …

That’s right, it doesn’t just measure heart rate. It uses an accelerometer and gyroscope to accurately track movement, and a PPG sensor to monitor hea…

Yes, as sensor technology continues to advance, head-mounted wearables will become more diverse and intelligent. Feel free to ask any questions you ma…

That’s right, it measures brain waves and is used for concentration, sleep analysis, brain-computer interfaces, and more. Thanks to the more comfortab…

Yes, PPG optical sensors can be used to measure changes in blood flow in the head to determine heart rate. While there’s some signal noise due to move…

Cameras capture the surrounding environment and display AR content, or are used for functions like facial recognition and gesture recognition. These d…

An IMU is a sensor that combines an accelerometer, a gyroscope, and sometimes a magnetometer. It measures movement, rotation, and position, and is use…

Exactly. Athletes track HRV to see if they’re recovered or overtraining. Low HRV after workouts can mean your body’s still under stress, so it’s a sig…

Most use optical sensors, like the ones in Apple Watch or Garmin, to track your pulse and estimate the intervals between beats. It’s not as precise as…

Often, yes. When you’re stressed, your sympathetic nervous system kicks in—your “fight or flight” mode—and your heartbeats become more regular, which …

Basically, HRV is the variation in time between each heartbeat. It’s not about how fast your heart’s beating, but how much those beats differ in spaci…

Feel free to ask any questions you have! Thank you.

Where you wear your wearable, how you walk, your surroundings, and other activities all affect pedometer accuracy. That’s why the intelligence of the …

Yes, GPS tracks your location outdoors and provides fairly accurate distance measurements. However, accelerometer-based distance measurement is primar…

Users can input their stride length directly, or it can be roughly estimated based on height or age. These days, some devices use technologies like ma…

That’s a good question! A pedometer uses an accelerometer to count steps, while an odometer calculates distance by multiplying the number of steps cou…

Please feel free to ask any questions you may have! Thank you.

GPS provides location, distance traveled, and speed, while the barometric pressure sensor detects changes in altitude. For example, when climbing a mo…

When used together, they can detect both the intensity and direction of movement, allowing them to better distinguish between walking, running, and ot…

A gyroscope measures the body’s rotational or directional movements. When you walk or run, your body sways slightly, right? By detecting these subtle …

That’s a good question! The accelerometer measures the magnitude and frequency of movement, and when running, it detects faster and stronger impacts. …

Thank you! I’m sure there will be more convenient and smarter wearables in the future. Feel free to ask any questions you may have!

That’s right, high-performance sensors can be expensive because they’re difficult to manufacture. That’s why we’re trying to lower costs through mass …
