  1. 21. Wearable Sensor Data Fusion for Human Stress Estimation

    University essay from Linköpings universitet/Reglerteknik

    Author : Simon Ollander; [2015]
    Keywords : stress; data fusion; classification; modelling; wearables; physiological sensors;

    Abstract : With the purpose of classifying and modelling stress, different sensors, signal features, machine learning methods, and stress experiments have been compared. Two databases have been studied: the MIT driver stress database and a new experimental database, where three stress tasks have been performed for 9 subjects: the Trier Social Stress Test, the Socially Evaluated Cold Pressor Test and the d2 test, of which the latter is not classically used for generating stress.

  3. 22. Multisensor Stress Monitoring For Non-Stationary Subjects

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Anette Hilmersson; [2015]
    Keywords : Monitoring; stress; photoplethysmography; PPG; transmissive; skin conductance; SC; sensor construction;

    Abstract : Monitoring stress in real-time, in a non-laboratory environment can be benecial in several applications. One of these, which have been the motivation for this thesis, is to to perform this measurement during Attention decit hyperactivity disorder (ADHD) diagnosis. READ MORE

  4. 23. Optomyography - Detection ofmuscle surface displacement using reflective photo resistor.

    University essay from KTH/Medicinska sensorer, signaler och system

    Author : Jammalamadaka Raghavendra; [2014]
    Keywords : Optomyography; Photoelectric sensors; Reflective photo resistor;

    Abstract : A human body can carry out many physiological complex processes which can be mechanical, electrical or bio-chemical. Each mechanical activity generates a signal that describes the characteristics of the particular action in the form of pressure or temperature. READ MORE

    Keywords : Optomyography; Photo-electric sensors; Surface EMG;

    Abstract : A human body can carry out many physiological complex processes which can be mechanical, electrical or bio-chemical. Each mechanical activity generates a signal that describes the characteristics of the particular action in the form of pressure or temperature. READ MORE

  6. 25. Spectrum Analysis of Heart Rate Variability (HRV)

    University essay from Lunds universitet/Matematisk statistik

    Author : Tiying Cui; [2013]
    Keywords : Mathematics and Statistics;

    Abstract : Heart Rate Variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. High frequency (HF) HRV signals (0.12-0.4 Hz), especially, has been linked to parasympathetic nervous system (PSNS) activity. READ MORE
