摘要：
先講一下柔性可穿戴器件的巨大潛力
Flexible wearable pressure sensors have drawn tremendous interest for various applications in wearable healthcare monitoring, disease diagnostics, and human–machine interaction

但是有限制：感知壓力範圍，在低壓下的低感知靈敏度，高壓下的機械柔性，複雜的製造過程限制應用
However, the limited sensing range (<10%), low sensing sensitivity at small strains, limited mechanical stability at high strains, and complicated fabrication process restrict the extensive applications of these sensors for ultrasensitive full-range healthcare monitoring

將本論文中製造的結構：
Herein, a flexible wearable pressure sensor is presented with a hierarchically microstructured framework combining microcrack and interlocking, bioinspired by the crack-shaped mechanosensory systems of spiders and the wing-locking sensing systems of beetles

講器件的效能：0.2-80%的形變，快速響應/恢復，高靈敏度，極低的檢測閾值，1000個週期的耐久度
The sensor exhibits wide full-range healthcare monitoring under strain deformations of 0.2–80%, fast response/recovery time (22 ms/20 ms), high sensitivity, the ultrasensitive loading sensing of a feather (25 mg), the potential to predict the health of patients with early-stage Parkinson’s disease with the imitated static tremor, and excellent reproducibility over 10 000 cycles.

此外，能用於E-skins，感知壓力分佈和接觸形狀，也能整合到機器人的腿和接到無線發射機上。

微裂縫的RGO片層包覆的PU泡泡沫

• 聚氨酯海綿(PU sponge) $2.5 \times 2.5 \times 1cm$使用氧氣等離子體預先處理5min，增加親水性(hydrophilicity) 此步驟非必須
• 將PU海綿浸入到GO溶液中(0.05mg/mL),將GO薄片整合到PU海綿上
• 接下來殘留在PU海綿上的GO片材，乾燥
• 將PU海綿浸入到60mL的水和肼( $N_2H_4 \cdot H_2O$), 120攝氏度， 1h。將GO還原到RGO。
• 最後在PU海面上獲得C-RGO片層

在微裂縫RGO片材上的PANI納米陣列的準備

典型的過程：
將上一步獲得材料浸入到40mL的 1M HClO4中，包含60uL的苯胺單體 (aniline monomer),之後，將99.95mg的APS新增到10mL的1MHClO4溶液中，攪拌知道溶解。將溶液倒入上述預製備的包含苯胺單體的溶液中，在5攝氏度下聚合8,16,24,32h

電子面板的製作

注意看一下這個是具體怎麼實現的
使用(65 mm × 65 mm × 10 mm)的海綿製作5 × 5的感知陣列。將銀膠料滴到上表面形成5 ×5的電極分佈，行和列分別用銅導線連線。同樣的方法在下表面執行一遍，最後在兩邊覆蓋一層絕緣層PDMS作為封裝。

上表面用行，下表面用列？
