dc.description.abstract | Wearable auditory sensors are critical in user-friendly sound-recognition systems for smart human-machine interaction and the Internet of Things. However, previously reported wearable sensors have limited sound-sensing quality as a consequence of a poor frequency response and a narrow acoustic-pressure range. Here, a skin-attachable acoustic sensor is presented that has higher sensing accuracy in wider auditory field than human ears, with flat frequency response (15-10 000 Hz) and a good range of linearity (29-134 dB(SPL)) as well as high conformality to flexible surfaces and human skin. This high sound-sensing quality is achieved by exploiting the low residual stress and high processability of polymer materials in a diaphragm structure designed using acousto-mechano-electric modeling. Thus, this acoustic sensor shows high acoustic fidelity by sensing human-audible sounds, even loud sounds and low-frequency sounds that human ears cannot detect without distorting them. The polymer-based ultrasmall (<9 mm(2)) and thin sensor maintains sound-detection quality on flexible substrates and in a wide temperature range (25 to 90 degrees C). The acoustic sensor shows a significant potential of auditory electronic skin, by recognizing voice successfully when the sensor attached on human skin is connected to a commercial mobile device running the latest artificial intelligence assistant. | - |
