At Lapland UAS the latest version of the ground embedded sensor has just been received and tested!

For over three months, an ambient light-based energy harvesting (EH) system has been operating at Lapland UAS. This setup uses an EH solution developed by Epishine to power a low-power Bluetooth Low Energy sensor—specifically, a RuuviTag developed by Ruuvi. The system draws energy from both indoor office lighting and natural outdoor light.

As the Vaasa Energy Week is kicking off in Vaasa, it's our pleasure to announce that Vaasa University is presenting their achievements in HE4T at their booth. Please make sure to visit them!

One activity within the HE4T project has been the development of a driver stage for piezoelectric crystals that generate ultrasonic signals. This work can in energy harvesting context be used to facilitate the power supply of e.g. bio-implantable sensors that are implanted under the skin. In such application, ultrasound is used for both...

One activity within the HE4T project has been the development of an integrated energy harvesting system designed for low-power energy sources and ultra-low-power applications. Designed during an M.Sc thesis project at LTU, the system was developed to offer support for an ultra-low-power micro controller from the Texas Instruments MSP430 series. The...

Epishine has released a development kit for their indoor lighting based light energy harvester solar panels. The panels are intended to operate at a relatively low illumination intensities. They are intended to operate between 20 to 1000 lux.

One activity within HE4T been to assist in power extraction from Microbial Fuel Cells (MFC) which is one research area within Biochemical Process Engineering at LTU. The fuel cells generate electricity by the oxidation of sulfide using bacteria. The long term goal with the use of multiple MFCs is to use the output power to energize...

The HE4T project's WP1.1 aimed to map industrial needs for energy harvesting (EH) across various regions. Three key insights emerged from the interviews conducted in different Nordic locations.

Franz Wikner, an Engineering Physics student at Luleå University of Technology has completed his thesis on fast wireless charging. The research done in the thesis has been done as part of the HE4T project and the topics are closely related to the project topics.

Since having built a simple testing rig on breadboard for interfacing TMP117 sensors with the MSP430 MCU, we've produced a PCB prototype to better evaluate possible LoRa radio solutions. After all, the purpose of the device is to autonomously report temperature readings wirelessly, while still having a fairly low power-consumption.
