Attendees will learn considerations of adding biometric sensors to wearable hardware designs, including optical and skin temperature sensor selection, placement, signal quality, optical overlay design, fit, electrodes, and ambient light blocking considerations. The presentation will cover some of the tradeoffs for performance versus power consumption and cost of their solution. We will discuss the impact of ambient light noise on performance and optical blocking techniques. The presentation will also cover methods to reduce noise due to motion artifacts, including band design, skin contact, and use of an accelerometer to mitigate noise in the system.
