摘要: Flexible and skin-attachable vibration sensors have been studied for use as wearable voice-recognition electronics. However, the development of to recognize human voice accurately with a flat frequency response, high sensitivity, flexible/conformable form factor has proved major challenge. Here, we present an ultrathin, conformable, vibration-responsive electronic skin that detects acceleration, which is highly linearly correlated pressure. This device consists crosslinked ultrathin polymer film hole-patterned diaphragm structure, senses voices quantitatively outstanding sensitivity 5.5 V Pa−1 over range. Moreover, this (<5 μm) exhibits superior conformity, enables exact recognition because it eliminates vibrational distortion on rough curved surfaces. Our suitable several promising applications, such security authentication, remote control systems vocal healthcare. Though are current technologies do not meet key performance requirements. authors report flexible sensor response
