Piet Bergveld is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Piet Bergveld rather than just read about it. In short: Piet Bergveld (Dutch pronunciation: [pid ˈbɛr(ə)xfɛlt]; born 26 January 1940) is a Dutch electrical engineer. He was a professor of biosensors at the University of Twente from 1983 and 2003.

Key takeaways

Piet Bergveld belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Piet Bergveld to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Piet Bergveld from memory before moving on to harder problems.

Reference excerpt

Piet Bergveld (Dutch pronunciation: [pid ˈbɛr(ə)xfɛlt]; born 26 January 1940) is a Dutch electrical engineer. He was a professor of biosensors at the University of Twente from 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 program was not available at the time. Between 1964 and 1965 he completed the 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 the challenge of discovering and measuring the origin of electronic activity in the human brain Bergveld began developing a new technique. In 1970, he completed the development of the ion-sensitive field-effect transistor (ISFET) sensor. It was based on his earlier research on the MOSFET (metal–oxide–semiconductor field-effect transistor), which he realized could be adapted into a biosensor for electrochemical and biological applications. In 1973, he earned his PhD at Twente, with a dissertation that explored the possibilities of ISFET sensors. Bergveld worked at the University of Twente from 1965 until he became emeritus status in February 2003. He had been a full professor since 1983. At the university he was one of the driving forces behind the expansion of biomedical technology research and one of the founding fathers of the MESA+ research institute. In 1995 Bergveld was awarded the Jacob Kistemaker prize by minister Hans Wijers. He was elected a member of the Royal Netherlands Academy of Arts and Sciences in 1997. In April 2003 Bergveld was made a Knight in the Order of the Netherlands Lion.

Worked examples

Example 1 — a first encounter with Piet Bergveld

Start with the simplest possible case. Write down what Piet Bergveld claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Piet Bergveld before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Piet Bergveld ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Piet Bergveld

In research: Piet Bergveld appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Piet Bergveld in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Piet Bergveld is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 20th-century Dutch people, Academic staff of the University of Twente, so understanding it makes those chapters shorter.
In everyday life: Look for Piet Bergveld outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
