Embodiment 1

[0085] Piezoresistive nanocarbon inks printed onto cotton or blended fabrics were prepared as follows.

[0086] Prepare the TPU polymer solution by weighing 22 wt% TPU resin in DBE solvent in a glass bottle using a scale; place the bottle on a hot plate to dissolve the TPU resin in DBE (hot plate temperature: 120°C) 24h to obtain a 22% TPU solution. Then, weigh 0.28g of VX72R nano-carbon black and 5g of 22% TPU solution, 15g of DBE solvent, and use a vacuum mixer (1000rpm, 10 minutes) to mix the above paste to obtain piezoresistive nano-carbon ink.

Embodiment 2

[0088] Piezoresistive nanocarbon inks printed onto cotton or blended fabrics were prepared as follows.

[0089] TPU polymer solution was prepared by weighing 22wt% TPU resin in DBE solvent in a glass bottle using a scale; placing the bottle on a hot plate so that the TPU resin was in DBE (hot plate temperature: 120°C) Dissolved for 24 hours to obtain a 22% TPU solution. Then, weigh 0.14g of VX72R nano carbon black and 5g of 22% TPU solution, 15g of DBE solvent, and use a vacuum mixer (1000rpm, 10 minutes) to mix the above paste to obtain piezoresistive nanometers with different resistance ranges. carbon ink.

Embodiment 3

[0091] Piezoresistive nanocarbon inks printed onto cotton or blended fabrics were prepared as follows.

[0092] Weigh 30 wt% phenoxy (PKHH) resin in ethyl 2-butoxyacetate into a glass bottle using a scale and place the bottle on a hot plate to dissolve the PKHH resin in ethyl 2-butoxyacetate in the ester (hot plate temperature: 120° C.) for 24 hours to obtain a 30 wt % phenoxy resin solution. Then, weigh 0.2g of VX72R nano carbon black and 4g of 30% phenoxy resin solution, 15g of 2-butoxyethyl acetate solvent, and use a vacuum mixer (1000rpm, 10 minutes) to mix the above paste , to obtain piezoresistive nanocarbons.

Abstract

The present disclosure provides a flexible pressure sensor array and a manufacturing method thereof. The pressure sensor array comprises a pressure-sensing substrate, top electrodes and bottom electrodes. The pressure-sensing substrate comprises a piezoresistive material, a fabric and pressure-sensing columns. The top electrodes and the bottom electrodes are attached to the pressure-sensing columns. The pressure sensor array is ultra-flexible and conforms to 3-dimensional surface for pressure monitoring.

Description

technical field [0001] The present disclosure relates to a pressure sensor array, and more particularly, to a flexible pressure sensor array and a manufacturing method thereof. Background technique [0002] Wearable and lightweight electronic devices are becoming more and more popular in human life. Traditional tactile sensors are rigid and have a fixed size and shape. Printed pressure sensors on plastic foils such as polyethylene terephthalate (PET) and PI have traditionally been developed. These printed sensor arrays are flexible, but encounter reliability issues when applying them to soft surfaces such as chair pads and mattresses. The printed silver electrodes and pressure-sensitive material can crack when the sensor array is twisted or bent, especially when the sensors are placed on soft surfaces. Plastic foil substrates are flexible, but have difficulty conforming to three-dimensional (3D) objects with curved surfaces. [0003] Therefore, there is a need for a flex...
