“…It is shown that the VA probe structure has more potential to achieve low magnetic crosstalk with small volume than HA structure. When the distance d is less than 10 mm, the VA probe can obtain its smallest crosstalk 1.3% with a volume of 1.01 cm 3 , while the crosstalk of VA can only be reduced to 7.2% with a bulky volume of 2.33 cm 3 . In the process of reducing magnetic crosstalk by increasing the distance, the sensor volume increase of the probe with structure VA is smaller than that of probe with structure HA, which can be clearly verified by the two curve slopes in Fig.…”

“…The magnetic sensors have emerged as a promising new sensing technology in various biosensing applications for detection, identification, localization and manipulation of a wide spectrum of biological, physical and chemical agents in the past few years [1][2][3][4]. More stringent requirements for sensors have been put forward due to the unique working environment of biosensing, such as higher spatial resolution, more compact structure, and lower power consumption under the premise of fine sensitivity and detection resolution [3][4][5][6].…”

This paper demonstrates the probe structure optimization of coupled core fluxgate magnetic sensors through finite element analysis. The obtained modelling results have been used to optimize the probe structures from horizontal-to vertical-arrangements for magnetic crosstalk suppression and probe miniaturization. The finite element analysis show that with the same distance between each adjacent fluxgate elements, the magnetic crosstalk is suppressed by 6 times and the volume is reduced by 2 times after the optimization. Furthermore, the miniaturized probes with low magnetic crosstalk have been designed and implemented. The experimental results which showed more than 5 times suppression of magnetic crosstalk verified the simulation results. Therefore, the results provide detailed reference to cope with the contradiction between volume miniaturization and magnetic crosstalk suppression in magnetic sensor-array design.

“…[ 12–14 ] However, it is difficult for traditional electronic skin to simultaneously satisfy the demands for breathability, permeability, and comfortability. [ 15–18 ] Considering the human skin is able to excrete secretions from sebaceous glands and sweat from sweat glands through pores, electronic skin also needs the ability to exchange gas and water with external environment. [ 19,20 ] One straightforward method is to create holes in electronic skins, but recklessly creating holes in electronic skins will weaken their toughness.…”

Wearable, flexible, and even stretchable tactile sensors, such as various types of electronic skin, have attracted extensive attention, which can adapt to complex and irregular surfaces, maximize the matching of wearable devices, and conformally apply onto human organs. However, it is a great challenge to simultaneously achieve breathability, permeability, and comfortability for their development. Herein, mitigating the problem by miniaturizing and integrating the sensors is tried. Highly flexible and stretchable coaxial structure fiber‐shaped triboelectric nanogenerators (F‐TENGs) with a diameter of 0.63 mm are created by orderly depositing conductive material of silver nanowires/carbon nanotubes and encapsulated polydimethylsiloxane onto the stretchable spandex fiber. As a self‐powered multifunctional sensor, the resulting composite fiber can convert mechanical stimuli into electrical signals without affecting the normal human body. Moreover, the F‐TENGs can be easily integrated into traditional textiles to form tactile sensor arrays. Through the tactile sensor arrays, the real‐time tactile trajectory and pressure distribution can be precisely mapped. This work may provide a new method to fabricate fiber‐based pressure sensors with high sensitivity and stretchability, which have great application prospects in personal healthcare monitoring and human–machine interactions.

“…The magnetic field detection can usually provide more real-time and direct information compared with the electric field sensing, and gains a lot of attractions in biosensing area. Due to the more complex and weak magentic field generated in the biosensing application especially for disease diagnose, the magnetic sensor need to have higher spatial resolution, compact size, and low power consumption while having excellent sensitivity and detection resolution [6][7][8][9].…”

This paper presents a closed-loop detection strategy with significant potential to solve the detection defects existed in the residence-times difference (RTD) method of the coupled core fluxgate magnetic sensors. The external magnetic field (e.g. Earth's magnetic field), as the main source of these detection defects, has been analyzed by the theoretical investigation. To overcome such deficiencies, the close-loop detection method based on the analog-type RTD readout method and magentic flux-balance detection is utilized to implement external magnetic field real-time compensation and achieve a near-zero-field working state of the magnetic material. The fluxgate with the optimized detection strategy and vertical arrangement structure has been designed, fabricated and examined, and the preliminary results showed steady operation and a detection resolution of ±0.10 nT. The optimized detection method based on the balance detection concept proposed in this manuscript demonstrated a great potential to obtain the optimal detection performances which are embedded in the couplinginduced oscillation of nonlinear dynamics.
