The sensor is based on a piezoelectric micromachined ultrasonic transducer (PMUT) array that is bonded at wafer-level to complementary metal oxide semiconductor (CMOS) signal processing ...

His concept was to move the obstacle detection out of the hands of the person. He is accomplishing this by mounting an array of ultrasonic sensors around some tennis shoes. The concept behind this ...

The patent, titled “Ultrasonic fingerprint ... technical details of the sensor’s construction, including a stacked common electrode, a piezoelectric layer, and an array of pixel electrode ...

These soft ultrasonic sensors require tethering cables for data and power transmission, which largely constrains the user’s mobility. This work includes a small, flexible control circuit that ...
