Wearable device is a kind of computing equipment that can be installed on people, animals and objects, and can sense, transmit and process information. Sensor is the core device of wearable device, and the sensor in wearable device is the extension of human senses, which strengthens the function of human’s “sixth sense”, and it is the “core” tool for people/objects to communicate with the world, which opens the door to the “Perception Era”.

Smartwatches are able to realize a variety of functions, such as pedometer, heart rate monitoring, sleep monitoring, etc., through various built-in sensors and algorithms. Among them, digital barometric pressure sensor is one of the important sensors in smartwatch, which provides the smartwatch with information such as barometric pressure and altitude.

Gas pressure sensors enable remote meter reading, automatic fault alarms and data management, improving the energy efficiency and safety of gas monitoring.

Pressure sensors are a common type of pressure instrument and are used in a variety of industries. Users in the use of pressure sensors to determine how to detect micro-pressure pressure sensor is very important to detect micro-pressure pressure sensor according to the purpose of different detection items are not the same, of course, the detection method will also be different…

In recent years, along with the rapid development of science and technology, our daily life continues to be intelligent, digital and convenient. One of the “core souls” supporting these intelligent lifestyles is sensors. Sensors can help us transform information that is difficult to visualize and judge into more visual, accessible and accurate data, thus building the cornerstone of our new lifestyle.
There are many types of sensors, and the range of applications extends from the industrial field to all walks of life.

Blood pressure sensors are an essential core component of modern health monitoring and medical devices. They help users understand the status of their blood pressure in real time by sensing the pressure changes that occur as blood flows through the arteries. The article discusses different types of blood pressure sensors and their applications, including traditional piezoelectric sensors, capacitive sensors, and PPG (photoplethysmography) sensors in smartwatches.

Pressure, an invisible and immaterial physical quantity, plays an omnipresent role in our daily life and industrial production. From simple tire inflation to complex deep-sea exploration, the accuracy of pressure measurement is crucial. It is not only directly related to the quality of products, but also a core element to ensure production safety and prevent risks. In this context, gauge pressure and absolute pressure, as two basic pressure types in the field of industrial measurement, are becoming increasingly important. This article will guide you to explore these two concepts in an easy-to-understand way, and further extend them to the important application field of airtightness testing, to help you fully understand the key roles they play in modern manufacturing.

Have you ever wondered how a machine can interpret its environment and react accordingly? The answer lies in analog and digital sensors. Analog sensors enable machines to collect data from their environment, interpret it, and make decisions based on the information. For example, a car can detect obstacles in its path and a medical device can monitor vital signs. Digital sensors utilize software algorithms to interpret their inputs and generate outputs. They are essential to ensure the safe and efficient operation of machines.

In this paper, we will discuss the principles, types, and applications of blood pressure sensors in wearable devices and medical equipment, with a focus on the design and operation of digital blood pressure sensors, small blood pressure sensors, and built-in blood pressure sensor modules
