Smart Watch Solution

Diversified Smart Watch Functions Enhance the User's Experience
Smartwatches surpass the functional limitations of traditional watches. Through the integration of wireless and communication components such as LTE, GPS, NFC, Wi-Fi/Bluetooth, etc., smartwatches enable functions such as message synchronization, call answering, contactless payments, digital assistant capability, and Internet of Things (IoT) connectivity that improve and transforms the utility of these devices for its users.
The combination of various sensors is one of the keys to market segmentation. By integrating ECG/EKG and PPG sensors, smartwatches can capture the user's heartbeat and pulse oximetry, respectively. Combined with pressure sensors, ambient light sensors, 6-axis sensors together with algorithms, a smartwatch can also infer and report user blood pressure, sleep status, lactate threshold heart rate, and maximum oxygen uptake. These functions can not only detect potential physical anomalies but also assist athletes to create better training programs and reduce the chance of accidental injury.

Power management optimization is also critical for any wearable device. The selection of batteries in combination with the efficiency of all components including those related to power becomes crucial when maximizing battery life. In addition to using low-power MCUs as the main processor, power management ICs are used to reduce current consumption. Furthermore, wireless charging is also an attractive option to further enhance convenience and safety.
