Wearable technology


Technologies for enhanced user experience in your wearable devices

We help our customers develop technologies enabling hi-tech functionality in wearable items such as clothing, sports trackers, headsets, watches and glasses. We overcome challenges of form, function and integration with novel sensing capabilities, energy harvesting technologies and software algorithms. With both MEMS or printed electronics, our capabilities are strong and our intellectual property is considerable.

From concept through pilot production

Apply VTT's strong intellectual property (IP) to your wearable device project. Benefit from our unique pilot production environments for both microelectromechanical (MEMS) and printed electronics (PE) components and systems.

We work with clients in a collaborative manner, developing commercially applicable solutions that combine a high level of functionality with cost-efficient production.


Energy autonomous wearable devices

Energy harvesting technologies developed by VTT can make wearable electronics self-powered and cable-free. VTT has broad competence in the field of electrical energy harvesting and power management for wearable devices. End users and integrators from a diverse range of markets can use VTT's new energy harvesting and storage technologies to address their power management challenges.

​​​Printed solar cells »

We develop ultra-thin, lightweight and flexible solar cells which can be mass manufactured by R2R printing technologies. Solar cells that can be customised to any size, shape and electrical performance required.

​ ​​​

Energy control »

We develop energy optimisation methods and solutions such as dynamic voltage and frequency scaling (DVFS) that offer a dynamic and flexible way of controlling the amount of energy used to perform necessary computations in wearable devices.

​ ​​​       ​ ​​​


Elastic and robust structures

We are active in the field of printed electronics and hybrid manufacturing of integrated smart systems. The research focuses on combining manufacturing technologies – such as roll-to-roll printed functionalities, injection moulding and traditional component assembly – to enable seamless integration of the new technology into traditional products at a comparatively low cost.

​​​Hybrid electronics »

We are developing a hybrid in-mould integration technology that enables seamless integration of novel optical, electrical, and mechanical features into 3D plastic products. With our approach, industrial product designers gain more design freedom.

​​​Wearable heating and cooling ​» 

We have invented a high-volume method for producing microscopic channels onto large areas of plastic film. Pumping hot or cold liquid through a network of these microchannels enables the temperature control of functional clothes.



Sophisticated data processing

There is an emerging need to turn wearable data into health insight that goes beyond simple recording and reporting.  We have the ability to combine, use and process information collected from different sources. We have competence in data analysis in real time and in environments with limited computing capacity, such as wearable devices. The benefit of our solutions for wearable devices lies in their energy efficiency, which has a big impact on battery life. Different kinds of visualisation techniques can be used to present multidimensional data to users in ways that allow them to immediately grasp the situation at that time.

Data science for wearable applications » 

We are continuously identifying novel data analysis methods and educating ourselves. We also contribute methodological research, in particularly in the fields of predictive analysis, anomaly detection and behavioural models.  Our current research focus is on real-time data analytics.

Data transfer between devices by touch » 

We have created a technology whereby a ring or wristband acts as a user interface, allowing files to be transferred directly from one screen to another by touch. The new technical solution is the first step towards the interactivity of various objects through a cloud service.


​ ​​​

Sensor integration 

We have one of the largest R&D programs for optical, electrical, biological and molecular sensing solutions in Europe.  We combine expertise in optical engineering, instrumentation and measurement science with deep application knowledge to solve challenging technical problems. The result is effective new products and solutions for next generation wearable devices.

​​​MEMS sensors »

VTT is known for its innovative, state-of-the-art MEMS devices. We design, model, simulate, fabricate and characterise silicon-based components and readout electronics, with a focus on surface and SOI MEMS technologies.

Optical microspectro-meters »

VTT's tuneable FPI filter technology enables miniaturisation of spectrometers into small, hand-held sensors. Our technology is robust and mass-producible, and eliminates the need for expensive linear array detectors. 

​ ​

Smart phone powered ECG »

We have developed a device that allows consumers to take an electrocardiogram (ECG) in the comfort of their own homes. The pocket-size device communicates with a smartphone.

​ ​​​

Zero power wireless sensors »

Wireless sensor networks are a key element in implementing the Internet of Things in several application fields such as wearable technology. VTT has developed the intermodulation communication principle in order to wirelessly read out passive sensors at long distances.

​ ​​​

Omnidirectional lenses »

We have developed a novel omnidirectional lens design that allows a full 360 degree panoramic view of the surroundings. The lens can be used for panoramic imaging in many applications such as action cameras, photography and teleconferencing.


 Wireless connectivity

We specialise in wireless network and device core technologies in antenna, radio systems and associated computing platforms.  The challenge ahead concerns the integration of cognitive and cooperative networks. Increased data throughput creates a need for more efficient use of resources, especially of energy and of the radio spectrum. At the same time, there is a need to increase the performance and interoperability of both devices and access networks. We are actively solving both issues.

Antennas and RF technologies »

We develop antennas, antenna arrays, components, circuits, modules and sub-systems for radio frequency communication and sensing applications. We collaborate with our customers from early phase concept research and development to final product optimisations.

​Omnidirectional lens, optical devices utilizing the lens and method for optical measurement

WO 2011089320 A1

The invention relates to an omnidirectional lens, an optical measuring device, and a method for optical measurement. The lens comprises a central portion, collecting optically in a first direction, and an edge portion, which surrounds the central portion, and which is arranged to guide the light arriving at the edge portion omnidirectionally relative to the said first direction essentially transversely relative to the said first direction. According to the invention, the edge portion is arranged to guide the light through the central portion. With the aid of the invention, it is possible to create, for example, a simpler laser radar.

​Optical system

WO 2012038601 A1

​A first camera and a second camera are integrated together in a common case. Each camera comprises a detecting component and an omnidirectional optical component for directing optical radiation from the environment towards the detecting component by four optical surfaces each omnidirectional optical component having a first side, a second side and a circumferential side. Detecting components transform optical images formed through the omnidirectional optical components on the detecting components into electrical signals and feed the electrical signals to the image processing unit. The image processing unit forms stereoscopic information on the environment on the basis of the electrical signals from different detecting components. The user interface presents information to a user on the basis of the stereoscopic information.   

Non-linear resonating sensor and a method

WO 2011121180 A1

This application presents a passive wireless resonating non-linear sensor that is typically based on a ferroelectric varactor. The sensor replies its data at an intermodulation frequency when a reader device illuminates it at two closely-located frequencies. The paper derives a theoretical equation for the response of such a sensor, verifies the theory by simulations and demonstrates a temperature sensor based on a ferroelectric varactor.
