K-Sense: Towards a Kinematic Approach for Measuring Human Energy Expenditure
نویسندگان
چکیده
Accurate energy expenditure monitoring will be an essential part of medical diagnosis in the future, enabling individually-tailored just-in-time interventions. However, there are currently no real-time monitors that are practical for continuous daily use. In this paper, we introduce the K-Sense energy expenditure monitor that uses inertial measurement units (IMUs) mounted to an individual’s wrist and ankle with elastic bands to determine angular velocity and position. The system utilizes kinematics to determine the amount of energy required for each limb to achieve its current movement. Our empirical evaluation includes over 3,000,000 individual data samples across 12 individuals and the results indicate that the system can estimate total energy expenditure with a 92 percent accuracy on average.

Introduction we aimed to introduce a 6-universal-prismatic-spherical (UPS) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. We proposed a strategy to provide a fast and accurate solution to the kinematic problem. The proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...

In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...
