Traditionally, traditional "intelligence, surveillance, and reconnaissance" (ISR) sensors are always made up of bulky antennas and large boxes that need to be fixed in place. Researchers at the US Air Force Research Laboratory (AFRL) and Harvard University are looking to shrink sensors to band-aid sizes, creating new possibilities for sensor and sensor applications. What other important things to watch in today's sensor industry?
US researchers develop new flexible “band-aid†sensors
Traditionally, traditional "intelligence, surveillance, and reconnaissance" (ISR) sensors are always made up of bulky antennas and large boxes that need to be fixed in place. Researchers at the US Air Force Research Laboratory (AFRL) and Harvard University are looking to shrink sensors to band-aid sizes, creating new possibilities for sensor and sensor applications.
The "Mixed 3D Printing" technology utilizes additive manufacturing to combine a flexible conductive ink with a substrate to form a resilient electronic component.
For example, the electronic components of the sensor are digitally "printed" into a sheet-like, bendable, stretchable elastomeric material. The price of this sensor may be cheaper than traditional products, but the real significance is to break through the limitations of traditional sensors, significantly reducing the weight of the next generation of ISR. Researchers at AFRL and Harvard's Weiss Bio-Inspired Engineering Institute said they have developed ways to implement this vision. The technical details have been published in the Advanced Materials magazine and are now being developed for practical applications.
Why should the sensor be manufactured with a 3D printer?
In recent years, there has been a class of "non-mainstream" newborns in the sensor family. They have a common feature, which is born in 3D printers. Although such sensors are still in the minority, as more and more practitioners turn their attention to 3D printing technology, "non-mainstream" is expected to become mainstream.
Is this a hype initiated by the concept of 3D printing? Why should the sensor be manufactured with a 3D printer? The 3D printing equipment, which has many excellent "genes" such as economy, high efficiency, environmental protection, high simulation, and support for personalized customization, is expected to be an ideal tool for producing sensors.
The Dajiang Mavic Pro2 camera will use a 1-inch sensor
According to foreign media Canon Rumors, Dajiang will bring us the second-generation Mavic Pro drone in March this year, and the camera of this drone will likely use a larger sensor. The news shows that the new Mavic Pro II drone in Dajiang may be equipped with a camera with a 1-inch sensor and a 28mm lens.
In addition, the new machine will also have a built-in 4820 mAh battery, which will increase the battery life to 35 minutes while adding a binocular vision sensor at the rear.
MEMS sensor and wireless technology combined to achieve building structure monitoring
According to a report by Mammus Consulting, Dacheng Construction Group of Japan recently announced that it has developed a building structure monitoring system in cooperation with Yokogawa, Nagano Japan Wireless Co., Ltd. and the University of Tokyo. Long-term structural stability monitoring can be achieved with newly developed high-precision MEMS (Micro Electro Mechanical Systems) sensors combined with wireless technology in the 920 MHz band.
Building structure monitoring system developed this time
The newly developed MEMS sensor is used in the building structure monitoring system: the vibration sensor has a resolution of 1 mgal (Note: 1 gal = 1 cm/s^2), and the strain sensor has a resolution of 1 nm, which has a longer maintenance period than the conventional sensor. It is possible to accurately measure minute deformations and vibrations generated in the structure over a long period of time.
Sensors have more than 180,000 vehicles, such as Highlander and Ralink, recalled by Toyota.
According to the website of the General Administration of Quality Supervision, Inspection and Quarantine, Guangzhou Automobile Toyota Motor Co., Ltd. and Tianjin FAW Toyota Motor Co., Ltd., in accordance with the "Regulations on the Management of Defective Automobile Products Recall" and the "Implementation Measures for the Management of Defective Automobile Product Recalls", go to the AQSIQ. The recall plan was filed and it was decided to recall a total of 181,797 cars from February 10, 2018.
In some vehicles within the scope of the recall, the airbag control system is equipped with an error sensor of the problem batch. The production conditions of the IC chip in the batch acceleration sensor are not appropriate, resulting in possible disconnection of some IC chips during the use of the vehicle. As a result, the air bag warning light is turned on, and the air bag cannot be deployed normally, posing a safety hazard. GAC Toyota Motor Co., Ltd. and Tianjin FAW Toyota Motor Co., Ltd. will check the production number of the airbag acceleration sensor assembled in the vehicle within the recall range, and replace the accelerometers belonging to the problem batch with qualified parts for free to eliminate safety. Hidden dangers.
With quasi-wireless and sensing technology, wearable devices are better sold
Sensors are another key element of wearable devices, with increasing levels of functionality, size, and power consumption. In addition to pressure sensors, temperature sensors, accelerometers, gyroscopes, heart rate monitors, and oxygen saturation sensors, there are even sensors on wearable devices that can be connected to plants to monitor watering.
In addition to raw data, the output of multiple sensors can be used to detect specific conditions and vital signs. For example, an increased heart rate, accompanied by high blood pressure and irregular breathing, may indicate a patient with a cerebral hemorrhage.
