Flexible electron is an important development direction in the future electronic field. At present, scientists have developed flexible materials with better electronic performance, such as arbitrarily folded and stretched transistor arrays, curved flexible screens, can be prepared on clothing Sensor and electronic skin, etc. However, if flexible electronic equipment wants to play its huge potential, it must also have a "hard-centered", which is the ability of wireless RF communications, only with this function, "Canada" mobile phones can be a reality.
At present, Tianjin University Precision Test Technology and Instrument National Key Laboratory, Precision Instrument and Optical Electronics Engineering, Tianjin University Nanchang Micro Technology Research Institute, in this direction, has achieved breakthrough progress in this direction, related research results "facing wireless RF communications "Flexible Film Bulk Acoustic Wave Filters Toward RadioFrequency Wireless Communication") published on May 17th, "Small" magazine, and is selected as a cover article as a key recommendation.
The mobile phone is an electronic device of a wireless radio communication technology set, which can quietly realize high-speed transmission of data. In today's smartphone era, not only the collection of numerous sensor signals, but also the transmission of the control signal, the interaction between the information flow between the device, and can be applied to massive node data transmission of the Internet of Things and large data. However, such a function of "powerful" mobile phones are still hard and unable to bend because it is still a research challenge for the flexible electronic equipment with high-speed wireless communication.
The Tianda Scientific Research Team created flexible RF filtering technology, and used a flexible RF filter that was successfully developed as an innovative process called FlexMems (flexible microelectromechanical system), and it can be directly applied to flexible electronic radio frequency communication. The research results were completed by Dr. Yisheng's guidance from Poishing Professor and Zhang Menglun Assistant.
The RF filter is an indispensable core base element in the wireless RF communication module. The role of the wireless RF communication module is to receive, transmit and fine processing (filtering, amplification, modulation, digital mode conversion, etc.) data and information, and the RF filter avoids mutual interference between radio frequency electromagnetic wave signals between different purposes. The role of screening a specific target electromagnetic wave signal is placed.
"We have developed flexible radio frequency filter part of electrical performance indicators have reached the level of commercial radio frequency filters in smartphones." Jiang Yuan said.
The team's first FlexMEMS process technology can produce a microelectromechanical device having a high precision movable microstructure on a ultra-thin plastic substrate, solving the surface rough and non-high temperature polymer material substrate and high quality film, high precision movable micro The structure in the design, manufacturing, and packaging of the structure.
In addition, this technology is not limited to manufacturing flexible radio frequency filters, and can also be applied to manufacturing a variety of flexible microelectromechanical devices such as pressure gauges, accelerometers, gyroscopes, ultrasound identification and imaging units, projection imaging units, microphones, etc. Flexible electronic devices have a stronger perceived world (such as virtual reality) and even affect the ability of the external world (such as reality).
"Next, we plan to develop a flexible electronic system with complete wireless RF communication functions on the basis of existing flexible radio frequency filtering technology. Not only can the mobile phone '可 可 可', can be bent, let the flexible electronic equipment have" communication " (Referring to wireless communication), "Reflections" (referring to the operation), "Memory" (referred to), and even "sense" (referred to "(referring to sensing) and" transformation "(referring to display, imaging, etc.) The ability of the world is also available at the time." Pang thinks.
