Ligna Energy has developed a printable battery, called S-Power. It is based on research in organic electronics. In order to demonstrate the functionality of the new batteries, an IoT device was developed. The demonstrator consisted of a Sensor for temperature and relative humidity (RH), LoRWAN communication and a circuit for energy harvesting. Photovoltaic cells from Epishine were used in order to be able to harvest energy in low light conditions. At an illuminance of 200 lux, the demonstrator was able to sample the temperature and RH and send it by radio communication every two minutes. If no light at all is available, the demonstrator can sample data and send it every 30 minutes for over 12 hours. / <p>Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet</p>
