Poly(vinylidene fluoride) (PVDF)‐based polymers demonstrate great potential for applications in flexible and wearable electronics but show low piezoelectric coefficients (e.g., −d33 < 30 pC N−1). The effective improvement for the piezoelectricity of PVDF is achieved by manipulating its semicrystalline structures. However, there is still a debate about which component is the primary contributor to piezoelectricity. Therefore, current methods to improve the piezoelectricity of PVDF can be classified into modulations of the amorphous phase, the crystalline region, and the crystalline–amorphous interface. Here, the basic principles and measurements of piezoelectric coefficients for soft polymers are first discussed. Then, three different categories of structural modulations are reviewed. In each category, the physical understanding and strategies to improve the piezoelectric performance of PVDF are discussed. In particular, the crucial role of the oriented amorphous fraction at the crystalline–amorphous interface in determining the piezoelectricity of PVDF is emphasized. At last, the future development of high performance piezoelectric polymers is outlooked.

“…In recent years, flexible electronics, which is mainly the application of solution processable organic semiconductors in electronic device fabrication, has attracted considerable research attention. [1][2][3][4][5][6][7][8] Significant progress has been achieved in improving the charge carrier mobilities and air stabilities of organic semiconductors. Various small-molecular solution processed organic semiconductors, such as 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS pentacene), 9-11 5,6,11,12-tetraphenyltetracene (rubrene), [12][13][14] 2,7-dioctyl [1]benzothieno [3,2-b] [1] benzothiophene (C 8 -BTBT), [15][16][17] and 2,7-didodecyl [1]benzothieno [3,2-b][1]benzothiophene (C 12 -BTBT) [18][19][20][21] based thin film transistors have been reported with mobilities close to or even higher than 10 cm 2 V À1 s À1 by various research groups.…”

“…Researchers have designed and fabricated various electrochromic devices (WO 3 //PANI, V 2 O 5 //PANI, WO 3 //ITO, etc.) that can adapt to different sensing systems. − For example, Ha et al integrated a strain sensor with an ECD based on V 2 O 5 thin films and polyaniline (PANI) nanofibers, in which the color mode changes from yellow to dark blue as the strain increased . Up to now, many research studies have made remarkable pioneering achievements in the field of electrochromic sensors.…”

Temperature sensors have attracted great attention for personal health care and disease diagnosis in recent years. However, it is still a great challenge to fabricate reliable and highly sensitive temperature sensors that can convert physiological signals into easily readable signals in a convenient way. Herein, an integrated smart temperature sensor system based on a traditional temperature sensor and electrochromic display is proposed for real-time visual detection of temperature. Significantly, a voltage-regulated electrochromic device (ECD) based on tungsten oxide (WO3) and polyaniline (PANI) as the real-time visualization window was integrated into the platform to provide feedback on the temperature change. The ECD would change its color from green to blue based on the electrical signal of the temperature sensor, resulting in a visualized readout that can be monitored through our naked eye. Additionally, the smart temperature sensor system possesses an extremely durable property and cycle stability, remaining around 90% of the initial value even after 15,000 s continuous cycle. Thus, the novel design and low power consumption advantages make it a good candidate to pave the way for developing interactive wearable electronics and intelligent robots as real-time temperature feedback systems.
