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 ... -
Artificial Lateral Line Sensors - Developing Surface Sensors for Flow Detection around Adaptive Hydrofoils
Vestad, Håvard Nitter (Master thesis, 2018)In search for more efficient propulsion through water, many methods for improving on the existing hydrofoil and propeller designs we use today have been suggested, the topics of adaptive hydrofoils and propulsion systems ... -
Experimental Investigations of an Icing Protection System for UAVs
Hann, Richard; Borup, Kasper Trolle; Zolich, Artur Piotr; Sørensen, Kim Lynge; Vestad, Håvard Nitter; Steinert, Martin; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)UAV icing is a severe challenge that has only recently shifted into the focus of research. Today, there are no mature icing mitigation technologies for UAVs, except for the largest fixed-wing drones. We are working on the ... -

On Fuzzy Front End Prototyping and Testing of Complex Sensor Problems
Vestad, Håvard Nitter (Doctoral theses at NTNU;2022:99, Doctoral thesis, 2022)Norsk sammendrag Denne oppgaven er addresert til forskere og produktutviklere. Den har som hensikt å gi innsikt i løsing av komplekse sensorproblemer i the fuzzy front end av produktutvikling. Sensorer bygger bro mellom ... -
Piezoresistive Chopped Carbon Fiber Rubber Silicone Sensors for Shedding Frequency Detection in Alternating Vortex Streets
Vestad, Håvard Nitter; Steinert, Ralf Martin (Chapter, 2019)In nature, fish use sensory input to feel and adapt to flow conditions. Creating solutions that mimic these capabilities need flexible and sensitive sensor solutions. In this paper we use readily available carbon fibers ...
