To achieve reliable flexibility and acceptable transparency for integrated electronics, the power supply sources of these devices have to meet the requirement of flexibility and transparency. Herein, we developed a facile and non-toxic way to manufacture all-solid-state supercapacitors with high capacitive performance, transparency and flexibility. The as-prepared g-C3N4 nanowires are distributed in Polyvinyl Alcohol (PVA) and Poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) solution, transparent film could be formed by vacuum filtration. The g-C3N4 nanowires provide pseudocapacitance and PVA and PEDOT:PSS matrix provides bendable and stretchable ability. The g-C3N4/PVA electrode achieves a specific areal capacitance of 3.51[Formula: see text]mF[Formula: see text]cm[Formula: see text] with transparency of 85%, and that of g-C3N4/PVA/PEDOT:PSS is 5.32[Formula: see text]mF[Formula: see text]cm[Formula: see text] with transparency of 72%. The facile process provides a reasonable architecture for the preparation of a variety of flexible, transparent and wearable electronic devices. The flexible and transparent devices show an instant response to the finger bending with the capacitance change of more than 25%, which provides the possibility for fabricating smart flexible device to monitor human health and motion detection.

Fluxgate magnetic sensors are especially important in detecting weak magnetic fields. The mechanism of a fluxgate magnetic sensor is based on Faraday’s law of electromagnetic induction. The structure of a fluxgate magnetic sensor mainly consists of excitation windings, core and sensing windings, similar to the structure of a transformer. To date, they have been applied to many fields such as geophysics and astro-observations, wearable electronic devices and non-destructive testing. In this review, we report the recent progress in both the basic research and applications of fluxgate magnetic sensors, especially in the past two years. Regarding the basic research, we focus on the progress in lowering the noise, better calibration methods and increasing the sensitivity. Concerning applications, we introduce recent work about fluxgate magnetometers on spacecraft, unmanned aerial vehicles, wearable electronic devices and defect detection in coiled tubing. Based on the above work, we hope that we can have a clearer prospect about the future research direction of fluxgate magnetic sensor.
