Apple studies strain sensors for Apple Watch to track strength training more accurately

CTOnews.com, August 15, according to foreign technology media myhealthyapple, Apple is currently studying strain sensors internally in order to make the Apple Watch better control the strength training scene.

According to the recruitment information of Apple's health technology team, Apple is recruiting engineers who simulate electronic products, hoping to develop better electromechanical systems using actuators, temperature sensors, strain gauges and photodiodes.

This suggests that the selected engineers will help design, build, test and troubleshoot early prototype health hardware, and the Apple team may be advancing biomechanical research and development on Apple Watch.

CTOnews.com Note: Apple Watch's current sensors include actuators, temperature sensors and photodiodes, but no strain gauges.

The strain gauge mainly measures the change of resistance when applying force, and it is widely used in motion tracking and physiological monitoring system.

In practical application scenarios, researchers can use strain gauges as non-invasive strain sensors to accurately measure the omni-directional strain of human skin and monitor blood pressure.

At present, Apple Watch mainly tracks calorie, time and heart rate data in aerobic exercise such as running and cycling, but in strength training scenarios, due to the disproportion of heart rate and load, it is unable to provide accurate insight, and the introduction of strain gauges can improve activity tracking in strength training scenarios.
