The application of sensors in different fields

Sensors used in electronic pills reportable disease <br> <br> according to World Health Organization data show that about 50% of patients failed to use prescription medications correctly. The United States has been conducting research on electronic pills this year. It hopes to solve this dilemma. Scientists invented an electronic pill that has sensors that can send information from your body to doctors.

Each pill contains a sensor built into it. When it is swallowed by the patient into the mouth, into the stomach, and the drug is partially digested by the stomach, the sensor can use stomach acid to bring power and send out information. This technology is seen as the hope for the future. The American company ProteusDigitalHealth is currently the developer of this technology. They think that this kind of technology can help doctors diagnose the condition more accurately and prevent the wrong medication from appearing. It can also help people use drugs more accurately.

Of course, this type of electronic pill has not yet been used clinically. This is mainly because people do not yet know how many side effects this electronic pill has. However, with the development of biosensors, this type of electronic pill will surely go clinically, allowing doctors to serve more patients. Choose the right prescription drug.

Apple's latest product is equipped with a large number of sensors iPhone5S <br> <br> Apple's latest products on the market iPhone5S is considered "the most forward-thinking" smartphone. With its large number of sensors such as the TouchID fingerprint scanner and the M7 motion sensor chip, this phone can perform many functions.

TouchID fingerprint sensor is likely to become the iPhone5S's biggest selling point, although its initial function is very limited, that is used to unlock the device and make shopping authorization in iTunes and AppStore, but Apple will gradually enable it to support other features, and even open to developers This sensor. This means that TouchID will have more possibilities.

TouchID sensors are based on Apple’s technology from AuthenTec. Last year, Apple acquired the Florida-based company. In the iPhone 5S, the TouchID provides a 500-pixel sensor per inch that scans the skin's surface from multiple angles.

Dan Riccio, senior vice president of hardware engineering at Apple, said: "Fingerprint is one of the best passwords in the world. You always carry this password. No two people have the same fingerprint." Apple said that users can scan up to five fingers. Fingerprints. Setting up this system requires the user to repeatedly press the finger at multiple angles on the sensor to allow the system to accurately scan the finger surface in three dimensions.

As an aid to the TouchID sensor, Apple also upgraded the iPhone5S Home button with a scratch-resistant sapphire crystal material. The button outer ring also has a steel probe ring, so the TouchID sensor can read the fingerprint information without requiring the user to sweep the finger on the button surface.

Apple acknowledges that the TouchID system is not without defects, and that high humidity and conductive debris can cause fingerprint read errors. In addition, it is difficult for the system to confirm the user's fingerprint after a finger injury. However, the user can choose to use any finger, not limited to the thumb or a specific finger.

TouchID does not store the scanned user's fingerprint in the sensor or is stored remotely in the iCloud cloud storage service. Encrypted fingerprint data is stored on the iPhone 5S's A7 chip. If the device is rebooted, or if it is not used for more than 48 hours, the data will be lost. In this case, the user only needs to re-enter the password.
