  1. 1. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marie-Ange Stefanos; [2023]
    Keywords : Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

    Abstract : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

  3. 2. Oscillator Based Readout System For Inductively Coupled Stretchable Resistive Strain Sensor

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Billy Mårtensson; [2023]
    Keywords : Sensor; Wireless; Stretchable Electronics; Technology and Engineering;

    Abstract : The development and use of stretchable electronics is a relatively new research field. However, the use of these kinds of electronics could prove fruitful when seeking to improve medical sensors and equipment. READ MORE

  4. 3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  5. 4. Potential of Smart-Inhalers in Reducing Human and Economic Costs of Erroneous Inhaler Use

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anton Grünfeld; [2022]
    Keywords : Unsupervised medical treatments; respiratory diseases; asthma; COPD; smart-devices; smart-inhaler; erroneous use; embedded systems; socio-economic effects; Oövervakad medicinsk behandling; lungsjukdomar; astma; KOL; smarta-apparater; smartinhalator; felaktigt användande; inbyggda system; socio-ekonomiska effekter;

    Abstract : This thesis investigates the possibilities of increasing efficacy and general improvement of unsupervised medical treatments by implementing electronics and embedded systems (so-called smart devices) to allow the physician to monitor or track the treatment and adherence of the patient to it. The diseases in focus are respiratory: asthma and Chronic Obstructive lung [Pulmonary] Disease (COPD). READ MORE

  6. 5. Simulation of THz Quantum Cascade Lasers

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Viktor Rindert; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) have since their invention in 1994 become a crucial source for mid-infrared and THz radiation. Mid-infrared QCLs have achieved room temperature operation while THz QCLs have not. As such, simulations are an important tool in order to achieve a THz QCL operational at room temperature. READ MORE
