Piet Bergveld
Piet Bergveld (; born 26 January 1940) is a Dutch electrical engineer. He was professor of biosensors at the University of Twente between 1983 and 2003. He is the inventor of the ion-sensitive field-effect transistor (ISFET) sensor. Bergveld's work has focused on electrical engineering and biomedical technology. Career Bergveld was born in Oosterwolde, Friesland on 26 January 1940. In 1960 he started studying electrical engineering at the Eindhoven University of Technology, he had preferred to study biomedical engineering but that was not available. Between 1964 and 1965 he did a master's degree at the Philips Natuurkundig Laboratorium. In the latter half of the 1960s Bergveld started working as a scientific employee at the Technische Hogeschool Twente (which later became the University of Twente). Intrigued by discovering and measuring the origin of electronic activity in the human brain Bergveld started working on a new technique. In 1970, he completed the development of the i ...

Oosterwolde, Friesland
Oosterwolde ( fry, Easterwâlde) is the largest town in the municipality of Ooststellingwerf in the east of Friesland, the Netherlands. The town was first mentioned between 1325 and 1336 as "tot Oesterwolde", and means eastern forest. Oosterwolde developed between two ''brinks'' (communal pastures). The Dutch Reformed church was built in 1735 as a replacement of a medieval church. Oosterwolde was home to 548 people in 1840. In 1886, Oosterwolde became the capital of the municipality of Ooststellingwerf. In 1887, Frico (nowadays: FrieslandCampina) opened a dairy factory in the village. The cooperative purchasing agency "Oosterwolde" opened factory in 1915 which is a combination of rational and Jugendstil ''Jugendstil'' ("Youth Style") was an artistic movement, particularly in the decorative arts, that was influential primarily in Germany and elsewhere in Europe to a lesser extent from about 1895 until about 1910. It was the German counterpart of ... architecture. Gallery Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biosensor
A biosensor is an analytical device, used for the detection of a chemical substance, that combines a biological component with a physicochemical detector. The ''sensitive biological element'', e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc., is a biologically derived material or biomimetic component that interacts with, binds with, or recognizes the analyte under study. The biologically sensitive elements can also be created by biological engineering. The ''transducer'' or the ''detector element'', which transforms one signal into another one, works in a physicochemical way: optical, piezoelectric, electrochemical, electrochemiluminescence etc., resulting from the interaction of the analyte with the biological element, to easily measure and quantify. The biosensor reader device connects with the associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. This ...

Knights Of The Order Of The Netherlands Lion
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the church or the country, especially in a military capacity. Knighthood finds origins in the Greek ''hippeis'' and '' hoplite'' (ἱππεῖς) and Roman '' eques'' and '' centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. Knighthood in the Middle Ages was closely linked with horsemanship (and especially the joust) from its origins in ...

1940 Births
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

BioFET
A field-effect transistor-based biosensor, also known as a biosensor field-effect transistor (Bio-FET or BioFET), field-effect biosensor (FEB), or biosensor MOSFET, is a field-effect transistor (based on the MOSFET structure) that is gated by changes in the surface potential induced by the binding of molecules. When charged molecules, such as biomolecules, bind to the FET gate, which is usually a dielectric material, they can change the charge distribution of the underlying semiconductor material resulting in a change in conductance of the FET channel. A Bio-FET consists of two main compartments: one is the biological recognition element and the other is the field-effect transistor. The BioFET structure is largely based on the ion-sensitive field-effect transistor (ISFET), a type of metal-oxide-semiconductor field-effect transistor (MOSFET) where the metal gate is replaced by an ion-sensitive membrane, electrolyte solution and reference electrode. Mechanism of operation Bio-FETs c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Field-effect Transistor
A ChemFET is a chemically-sensitive field-effect transistor, that is a field-effect transistor used as a sensor for measuring chemical concentrations in solution. When the target analyte concentration changes, the current through the transistor will change accordingly. Here, the analyte solution separates the source and gate electrodes. A concentration gradient between the solution and the gate electrode arises due to a semi-permeable membrane on the FET surface containing receptor moieties that preferentially bind the target analyte. This concentration gradient of charged analyte ions creates a chemical potential between the source and gate, which is in turn measured by the FET. Construction A ChemFET's source and drain are constructed as for an ISFET, with the gate electrode separated from the source electrode by a solution. The gate electrode's interface with the solution is a semi-permeable membrane containing the receptors, and a gap to allow the substance under test to come ...

Order Of The Netherlands Lion
The Order of the Netherlands Lion, also known as the Order of the Lion of the Netherlands ( nl, De Orde van de Nederlandse Leeuw, french: L'Ordre du Lion Néerlandais) is a Dutch order of chivalry founded by King William I of the Netherlands on 29 September 1815. The Order of the Netherlands Lion was until recently awarded to eminent individuals from all walks of life, including generals, ministers of the crown, mayors of large towns, professors and leading scientists, industrialists, high-ranking civil servants, presiding judges and renowned artists. Since 1980 the Order has been primarily used to recognise merit in the arts, science, sport and literature; others are awarded the Order of Orange-Nassau. Appointment to the grade of Commander (see below) is very rare (Nobel Prizewinners; the conductor Bernard Haitink towards the end of his life, and the dancer and choreographer Hans van Manen, for example). The Order ranks after the Military William Order, which is only awarded for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Netherlands Academy Of Arts And Sciences
The Royal Netherlands Academy of Arts and Sciences ( nl, Koninklijke Nederlandse Akademie van Wetenschappen, abbreviated: KNAW) is an organization dedicated to the advancement of science and literature in the Netherlands.
