Smart thermometer

Smart thermometer is a mathematics 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 Smart thermometer rather than just read about it. In short: A smart thermometer is a medical thermometer which is able to transmit its readings so that they can be collected, stored and analyzed. Since 2012 Kinsa has distributed smart thermometers to two million households across the US.

Key takeaways

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

Reference excerpt

A smart thermometer is a medical thermometer which is able to transmit its readings so that they can be collected, stored and analyzed. Since 2012 Kinsa has distributed smart thermometers to two million households across the US. The thermometers transmit their readings to an app on the users' phones. Users are then able to see a history of their temperature readings. The information is also consolidated to show an overall temperature map. This shows hot spots where the level of high temperatures is exceptional and so can be used to identify outbreaks of disease. Continuous readings can be provided by wearable or adhesive thermometers but it is difficult to measure core body temperature in this way. Invasive sensors can be attached in a hospital setting such as intensive care or neonatal care. For more general use, form-factors such as arm bands and earbuds have been tried. Novel technologies under development include skin tattoos using flexible electronics and deep body heat flux sensors.

Worked examples

Example 1 — a first encounter with Smart thermometer

Start with the simplest possible case. Write down what Smart thermometer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Smart thermometer 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 Smart thermometer 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 Smart thermometer

In research: Smart thermometer appears in mathematics 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 Smart thermometer 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: Smart thermometer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Medical equipment stubs, Medical statistics, Medical testing equipment, so understanding it makes those chapters shorter.
In everyday life: Look for Smart thermometer 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.

Frequently asked questions

What is Smart thermometer in simple terms?

Why does Smart thermometer matter?

Because it connects several mathematics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Smart thermometer?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
