3DPIEZOMEMS

Microelectromechanical systems (MEMS) support the acceleration of existing microelectronic systems trends including edge computing, robotics & automation, Industry 4.0, mobility, biometrics, and augmented/virtual reality. In these applications, the performance of the current MEMS devices needs to be improved vastly in the field of latency, accuracy, sensitivity, energy efficiency, fail- operational level reliability and miniaturization. However, shortcomings in the current approaches to MEMS design limit the prospects. At the MEMS component level, sensing is achieved by static or resonant motion in mutual or perpendicular directions as the motion being measured. Currently, this directional behaviour require complex designs that adds to costs in manufacturability, increased device sizes and waste.
This project focuses on a disruptive new approach to fabricating MEMS components. The technology, called 3DPiezoMEMS, addresses the problem of simultaneous in- and out-of-plane element motion. This is enabled by depositing piezoelectric aluminium nitride (AlN) on the vertical and horizonal surfaces of a MEMS element, giving the design fully unhindered 3D-motion. Having fully integrated 3D-motion reduces MEMS element complexity, reducing overall the costs and size of MEMS devices. In addition, the use of PiezoMEMS brings significant power reduction for the actuation and sensing due to the intrinsic mechanical-electrical coupling behaviour of piezoelectric materials.

A-GATE

Hyperspectral imaging technologies are expected to be used in our daily life, for example, for agriculture, food industry, surveillance, safety, environment and medicine applications. This A- GATE project aims to prepare the commercialisation of our newly-invented miniaturized spectrometers. The project will research the first-of-its-kind low-cost high-efficiency miniaturized hyperspectral imaging array sensors, and then bring industrial utilization and market exploitation to the researched hyperspectral imaging sensors for commercialisation preparation.

ARTEMIS

Spatial Audio is a growing industry that enables immersive and interactive audio experiences for more prominent sectors such as virtual and augmented reality, gaming, film, and music. The currently available Spatial Audio recording and encoding tools in the market are expensive. They have low resolution, which limits the adoption of the format as well as the quality of the created content.

BATTERY MONETIZER

A huge automotive batteries boom is imminent in electric transportation. Besides that, various electricity grid, commercial and industrial, as well as residential needs drive a rapid growth of stationary batteries. The best way to get the most value out of a battery is to use it for multiple purposes efficiently. However, optimizing revenues from such multi-use is a difficult, continually repeating task. It is difficult because of uncertainties, various timescales, and numerous constraints plus alternative costs and incomes involved. Today, many batteries are used based on fixed plans and limited to a single service. This does not utilize the full potential of the battery, and natural resources consumed in producing the batteries are partly wasted. Our solution applies a novel combination of modelling and artificial intelligence to optimizing the usage plan of a battery for the day ahead. Our solution takes into account on one hand the requirements of the various markets or usages, and on the other hand the non-linear properties of the battery itself.

IMMUNATE

Immunate develops microscopy technology with the goal of significantly enhancing the adoptability of 3D cell culture in research and industry. Transitioning from conventional 2D culture to the 3D culture is expected to open new horizons for research and industrial processes, particularly, in the area of cancer-treatment development. Specifically, we aim to significantly enhance repeatability of 3D culture samples, and the applicability of 3D culture in cancer-drug discovery, screening of cancer-drug efficacy, and personalized cancer medicine. The technological realization is based on a software, and a device that can be provided as stand-alone, or as microscope add-on. Immunate is currently a research to business (R2B) project of Business Finland, and it is led by Aalto University and the University of Helsinki with spinoff ambitions in Q1/2023.

MILLISCAN

Millimeter wave imaging is used to search for hidden objects in security screening applications. Millimeter waves penetrate ordinary clothing well and the short wavelength allows adequate resolution for personal inspection applications. The technique can detect both metallic and non-metallic objects. The MilliScan project is developing an imaging method that is much simpler to implement: the technology is based on a dispersive hologram connected to a high-speed integrated millimeter-wave transceiver and neural network. The neural network interprets complex reflection as images in real time.

The technology enables remarkably light mechanical implementation without moving parts, demanding installation work, or long start-up time. In the past, millimeter wave imaging has been used only in the most critical destinations, such as airports. The cost benefit of the new technology is significant, and the commercial outcome of the project is expected to find new markets where millimeter-wave imaging could not previously be introduced due to cost, size, or frequent maintenance required.

NANOTHRUST

Compressed air systems are widely used in industry due to, among other things, their ease of use, operational safety and environmental friendliness, and compressed air can be considered one of the basic commodities essential for most industries. However, compressed air is the most expensive energy in industry - in large EU countries, industry uses up to 7-12% of all its electricity to produce compressed air. The project investigates the utilization of waste heat to produce compressed air.
