The innovative system functions with the help of a large battery-like storage device which can be charged up slowly but very quickly discharged. Find out more.

Artificial hip joints made of ceramic

The metal alloys used in conventional surface replacement artificial hip joints suffer from the problem that metal particles abraded by friction in the joint can reach the patient’s bloodstream. This often gives rise to health problems. In order to avoid this situation Empa staff have, in collaboration with colleagues from the company Metoxit AG, developed an artificial hip joint of high-performance ceramic. This material is not only more wear resistant, but is also better tolerated by the human body. More.

Needle-free blood sugar measurement
In order to monitor the blood sugar level of premature babies, doctors must draw blood samples, which causes pain and stress for the tiny patients. To avoid this Empa scientists working together with staff at the Zürich University Hospital have developed a new sensor called “Glucolight”. The new device measures blood sugar levels directly through contact with the skin, which in premature babies is very thin. The novel instrument uses a light-controlled membrane technique developed at Empa. Find out more.
A chest strap for the heart

In order to allow the long-term monitoring of patients with heart and circulatory problems, Empa has developed a chest strap which incorporates flexible humidifying elements. The latter produce a kind of artificial sweat, thereby moistening the skin under the electrodes, which is necessary for the optimal measurement of electrical signals from the body. To date gel electrodes have been used for monitoring devices, but these dry after 24 hours, thereby becoming usable. Read more.

This is a combination that has been lacking until now in modern interior design. The new «noise-quenching» curtains have just gone onto the market. More information on the new curtains can be found here.

Artificial turf with upstanding qualities
Empa researchers and scientists from the «Institute for Rapid Product Development» at the ETH Zurich, together with TISCA TIARA, a Swiss manufacturer of artificial turf, and the German fiber manufacturer Schramm GmbH, have developed a novel fiber for use in making artificial turf. The bi-component fiber returns to an upright position again and again thanks to a “hard core” but its soft sheath prevents abrasions and grass burns when players fall or slide on the surface. The turf has already been laid on two football pitches in Switzerland. More information on the new artificial turf can be found here.
Repairing spray coatings
The maintenance interval of water turbines is determined by the degree of erosional wear which the blades suffer. Repairs are time consuming and expensive since dismantling and reassembling a turbine can take up to several months, depending on the type involved. The use of hard coatings increases the operating lifetime of the turbine blades but partial damage to the coatings frequently occurs. Empa and the firm Stellba Schweisstechnik AG have together developed and patented a method of partially repairing these spray coatings of tungsten carbide composite material. The good results obtained in laboratory studies have been confirmed by practical tests on water turbines, and the method is now being used successfully in commercial applications.
Two-component fiber improves the properties of concrete
In a project supported by the Innovation Promotion Agency (CTI), a team of Empa scientists and their industrial partner, the fiber manufacturing company fibrotec ag, have developed an economical polymer fiber which can withstand high mechanical loads. They were assisted by a new production process which allows the manufacture of fibers made of two components. The core of the newly developed fiber is made of polypropylene (PP) whilst only the thin fiber sheath is made of a special, tailor-made polymer which is chemically and mechanically ideally suited for use in building materials using a cement binder. The bicomponent fiber is already commercially available and is produced by Brugg Seiltechnik Holding AG. More information on this product can be found here.
DownMat – an air mattress filled with goose-down
Top-level mountaineers climbing in extremely cold conditions at high altitude need not only a top-quality sleeping-bag but also a highly insulating mat to sleep on. In cooperation with the company Exped, Empa has developed a functional example of such a mat, consisting of goose-down filled air chambers which retain their shape under pressure. Measurements made at Empa showed that the thermal insulation of the new mats is 5 times better than conventional types. The idea was taken further by the outdoor-equipment suppliers Exped AG who, jointly with Empa, have applied for a patent. After further development the sleeping mat is now being produced commercially and is being sold very successfully under the brand name “DownMat“.
Wireless sensor network
The Stork Bridge in Winterthur was fitted with a total of seven sensors developed by Empa for long term testing purposes in the course of the EU project ”Sustainable Bridges“. The sensors monitor vibration levels in the bridge structure and other unusual mechanical behavior, and if necessary raise the alarm at Empa via a radio link and internet connection. The advantages of this remote monitoring system is that it is rapidly installed, very flexible and economic, since wireless sensors obviate the need for fitting the bridge with expensive cabling systems. The technology is now being commercialized by the Empa spin-off company DecentLab GmbH.
PPMS-AFM – a high precision measuring instrument
The PPMS-AFM is a high precision measuring instrument which unites surface analysis techniques on the nanometer scale with a device for measuring macroscopic properties, known as the PPMS® (Physical Properties Measurement System). The technology was developed at Empa and has been successfully transferred to the startup company NanoScan AG. In 2009 NanoScan began marketing the PPMS-AFM on a commercial basis under license to Empa. Since then the company has further developed the technology and is marketing the system internationally in collaboration with IONTOF, another of Empa’s industrial partners.
Metallized fibers using low pressure plasma method
At the end of 2007 Empa transferred the rights to its patent for a special fiber coating process to Tersuisse Multifils SA in Emmenbruecke, at the same time handing over its pilot plant to the company. The key to Empa’s success is a new fiber guidance system. On the one hand this allows a more rapid coating process and on the other it leads to the metal being applied more efficiently to yarns and fibers, which reduces the metal consumption. Both factors help to reduce manufacturing costs significantly, ensuring that in comparison to the conventional electrochemical process the advantages of the new technology take center stage. More information on this product can be found here.
Cooling system for multiple sclerosis patients
Empa scientists have developed ultra-light cooling garments for those suffering from multiple sclerosis (MS). Cooling trousers and shirts have been available on the market since April 2007, manufactured by Unico swiss tex GmbH, to whom Empa has transferred its patent. The small, innovative Swiss enterprise aims to market these products successfully in Switzerland, Germany and possibly even the USA. Cooling helps alleviate symptoms in 60 to 80 per cent of all MS patients. Further information on the cooling system is available here (m4v-Datei, 65 MB).
Jun Funori – Red algae for consolidating, aged and powdery painted surfaces
Funori, an adhesive material prepared in Japan from red algae of the family Gloiopeltis, has sparked the interest of restorers of art works, because of its ability to consolidate and strengthen layers of paint which have become lackluster and powdery with age. As a natural product, funori comes in varying qualities, and to tackle this problem a special purification process was developed jointly by the ETH Zurich’s Institute of Historic Building Research and Conservation, Empa and the Conservation Center of the Swiss National Museum. The resulting pure material, known as JunFunori (jun = pure) is a standardized product which has been tested by experts over a period of years. JunFunori offers conservators an improved consolidating agent which allows them to repair aged and powdery painted surfaces without changing them visually. Jun Funori is manufactured exclusively by the Lascaux company.
Zumikon Particle Separator
There are many good reasons which make wood an environmentally friendly source of energy. In particular, the fact that it is a CO2 neutral, renewable resource is an important advantage. In order that the fine particulate emissions of wood burning appliances do not act as a brake on the further development of wood as a fuel, Empa in cooperation with the Swiss Federal Office of the Environment (FOEN) has pushed forward with the development of a particle separator for small wood burning stoves. The further development of the prototype into a market-ready product has been taken on by the firm Rüegg Cheminée AG, who now offer the finished product commercially on the international market.
