Apple, Garmin, Samsung, Google or Amazfit? I compared each one against a chest strap for heart rate accuracy and found a ...

Dive into Part III of the Feynman Lectures as we explore the fixed bead parabola accelerometer! This tutorial breaks down the physics principles, step-by-step calculations, and practical applications, ...

Objective Although 30 min/day of moderate-intensity physical activity is suggested for preventing type 2 diabetes (T2D), the current recommendations exclusively rely on self-reports and rarely ...

Objectives To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods We conducted a harmonised meta-analysis including nine ...

Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered—could years of honed skill be replaced by bruteforcing the ...

Heart rate tracking is increasingly common among fitness enthusiasts, and understandably so. Whether it is a rugged outdoor smartwatch or a discreet smart ring, smart wearables can help you determine ...

Abstract: In this study, we assessed the frequency response and amplitude response characteristics of a cantilever-type hetero-core fiber optic accelerometer with an aluminum coating. Additionally, ...
