Flexible, compressible and conductive aerogels were fabricated by incorporating polyaniline (PANI) into bacterial cellulose/chitosan (BC/CH) composites through facile freeze-drying technique. The PANI/BC/CH aerogel fabricated with the BC:CH weight ratio of 1:1 displayed the highest resistance response and showed extremely high sensitivity (1.41 kPa⁻¹), low pressure detection (32 Pa), wide range of pressure deformation and extraordinary stability as a piezoresistive sensor. Polydimethylsiloxane (PDMS) was embedded into PANI/BC/CH aerogels to form PANI/BC/CH PDMS composites that displayed good stability under large mechanical deformation. Furthermore, applications of PANI/BC/CH aerogels and PANI/BC/CH/PDMS composites in piezoresistive sensors for wearable devices were also reported, which could detect human motions, ranging from joint movement to speech recognition, thus suggesting feasibility in health monitoring systems.

通过将聚苯胺（PANI）通过快速冷冻干燥技术掺入细菌纤维素/壳聚糖（BC / CH）复合材料中，制成了柔性，可压缩和导电的气凝胶。BC：CH重量比为1：1的PANI / BC / CH气凝胶显示出最高的电阻响应并显示出极高的灵敏度（1.41 kPa ^-1），低压检测（32 Pa），广泛的压力变形范围以及作为压阻传感器的非凡稳定性。将聚二甲基硅氧烷（PDMS）嵌入PANI / BC / CH气凝胶中，形成PANI / BC / CH PDMS复合材料，该复合材料在较大的机械变形下显示出良好的稳定性。此外，还报道了PANI / BC / CH气凝胶和PANI / BC / CH / PDMS复合材料在可穿戴设备的压阻传感器中的应用，该传感器可以检测人体运动，从关节运动到语音识别，从而表明在健康监测系统中的可行性。
