A Combined Photoplethysmography and Force Sensor Prototype for Improved Pulse Waveform Analysis

Solberg, Fredrik Samdal; Kohtala, Sampsa Matias Ilmari; Vestad, Håvard Nitter; Steinert, Ralf Martin (Chapter, 2019)

Pulse detection has in recent years received extensive attention in physiological health monitoring, and continuous blood pressure estimation models based on pulse waveform analysis have shown great promises. Two widely ...
Design and Development of Wearable Blood Pressure Monitoring Device

Solberg, Fredrik Samdal (Master thesis, 2019)

I 2016 utgjorde hjerte- og karsykdommer 31% av alle dødsfall på verdensbasis, og hypertensjon er blant de viktigste årsakene til disse. Det har derfor blitt forfektet at høyt blodtrykk skal vurderes som et problem av ...
Wrist ballistocardiography and invasively recorded blood pressure in healthy volunteers during reclining bike exercise

Steffensen, Torjus Lines; Schjerven, Filip Emil; Flade, Hans Martin; Kirkeby-Garstad, Idar; Ingeström, Emma Maria Lovisa; Solberg, Fredrik Samdal; Steinert, Martin (Peer reviewed; Journal article, 2023)

Objective: Ballistocardiogram (BCG) features are of interest in wearable cardiovascular monitoring of cardiac performance. We assess feasibility of wrist acceleration BCG during exercise for estimating pulse transit time ...
