1. 1. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Anders Lundberg; [2021]
   Nyckelord :Relative dielectric constant; relative permittivity; PCB substrate material;

   Sammanfattning : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. LÄS MER

3. 2. Comparative Life Cycle Assessment of Cardiac Monitoring Devices : A Case Study

   Master-uppsats, KTH/Industriell produktion

   Författare :Samruddha Kokare; [2020]
   Nyckelord :Life Cycle Assessment LCA ; Cardiac monitoring devices; Stretchable electronics; Livscykelbedömning LCA ; hjärtövervakningsanordningar; stretchbar elektronik;

   Sammanfattning : Current cardiac monitoring devices are rigid, bulky, and integrate poorly with the human skin, obstructing health monitoring for longer periods. With the miniaturization of electronics, soft and stretchable polymer substrate-based cardiac monitoring device is being developed at Mycronic AB to overcome the aforementioned issues and replacing the traditional rigid electronics-based cardiac monitoring devices.
