  "account": "Apple has announced its upcoming Watch Series 12 and Ultra 4 models, both featuring a new Health Sensing System and S11 chip. According to Apple's presentation at its fall event, these devices boast the \"most accurate heart rate sensing in a wearable.\" The Watch Series 12 and Ultra 4 will leverage the S11 chip in tandem with the Health Sensing System, enabling the watches to provide higher-frequency heart rate and heart rate variability (HRV) measurements compared to previous Apple Watch models. The Health Sensing System incorporates redesigned photodiodes arranged in a ring, allowing for more efficient light capture, as well as a larger electrode surface area for improved skin contact. Furthermore, the green LEDs in the optical heart sensors are larger and more power-efficient, and they are capable of measuring the user's heart rate every five seconds. With the Health Sensing System, users will have the option to monitor their heart rate in real-time through a new heart rate watch face feature, also referred to as a complication.",
