Abstract Wearable tensile strain sensors have aroused substantial attention on account of their exciting applications in rebuilding tactile inputs human and intelligent robots. Conventional such devices, however, face the dilemma both sensitive response to pressure bending stimulations, poor breathability for wearing comfort. In this paper, a breathable, insensitive sensor is reported, which presents fascinating properties including high sensitivity remarkable linearity (gauge factor 49.5...
We propose a design strategy to fabricate flexible bend sensor (BS) with ultrasensitivity toward airflow using all-poly(vinylidene fluoride) (PVDF) nanofiber web-based sensing elements and electrodes monitor human respiration. The unique electrospinning (rotational speed of collector 2000 rpm tip-to-collector distance 4 cm) silver nanoparticle interfacing was introduced prepare Ag-doped oriented PVDF web high β-phase content as element (AgOriPVDF, crystallinity ∼44.5%). After that, portion...
Abstract Multiple strain sensors are required to identify individual forces/stresses on human joints and recognize how they work together in order determine the motion’s direction trajectory. However, current cannot detect differentiate their contributions motion from sensors’ electrical signals. To address this critical issue, we propose a concept of unimodal tension, bend, shear, twist with piezoelectric poly L-lactic acid films. We then construct an integrated sensor (i-US) using prove...
Stretchable strain sensors have promising applications in flexible electronics field, such as artificial skin, health monitoring, and smart wearables. However, their anti-corrosion property, outstanding sensitivity, environmental adaptability of still remain a great challenge. Herein, porous film was constructed by coating the stack conductive fiber network with 1H,1H,2H,2H-perfluorodecyltriethoxysilane array via molecular self-assembly, which formed superhydrophobic surface on film. The...
Polymer/graphene composites have attracted much attention for their conductivity and other functions. To control structure of the more effectively, we adopted suction filtration combined with layer-by-layer (LbL) method based on our proposed particle construction by using polystyrene/graphene (PS/rGO) composite particles as building blocks to prepare PS/rGO having a graphene orientation-3D network binary structure. The resulting had an excellent 1344.3 S/m at rGO content 2.10 vol %. Besides,...
Lock-stitch embroidery has been the centre of much interest as a versatile and precise method producing conductive tracks in fabrication wearable electronic devices. However, improper parameter settings could result nonconformity damage coating yarns. In this study, we evaluate appearance quality, dimensional stability electrical resistance by taking into account embroidering speed (ES), stitch length (SL), needle thread pre-tension (NTP) direction (ED). The are embroidered onto knitted...
Despite the importance of respiration and metabolism measurement in daily life, they are not widely available to ordinary people because sophisticated expensive equipment. Here, we first report a straightforward economical approach monitoring respiratory function metabolic rate using wearable piezoelectric airflow transducer (WPAT). A self-shielded bend sensor is designed by sticking two uniaxially drawn poly l-lactic acid films with different cutting angles, then mounted on one end plastic...

This article proposed the structural design of micro milling machine tool, three schemes have been protocoled according to parameters. The third scheme has chosen by comparing structure and function, static dynamic characteristics, which is a gantry tool realizes multi-axis multi-functional milling. Then characteristics were analyzed ANSYS software. Static analysis results: maximum deformation 0.6μm, equivalent stress 0.27MPa, it good characteristics. Modal get first six natural frequencies...
One-piece flow is one of the effective tools lean production. Many garment enterprises expect to implement it in their own enterprises, but a lot difficulties exist implementation process. In this paper, takes an example well-known processing enterprise and study one-piece process pair jeans pipeline. By nearly year tracking research, paper systematically summarizes pre-production preparation production maintenance flow. It demonstrates detail on how achieve improvement hardware, software...
Epidermal electronics employed on human skin for the long term require good breathability and nonforeign wearing. In this work, we combine phase separation spray coating to fabricate a porous ultrathin electrode within minutes as well micrometer-scale pressure sensors. The resulting electrodes show water vapor transmission rate of 18.4 mg·cm-2·h-1, sheet resistance 5.2 Ω/sq, thickness below 5 μm. introduction biogel further reduced electrode-skin impedance, which is lower than that...
