Two Capacitive Micro-Machined Ultrasonic Transducers for Wind Speed Measurement

This paper presents a new wind speed measurement method using a single capacitive micro-machined ultrasonic transducer (CMUT). The CMUT was arranged perpendicular to the direction of the wind flow, and a reflector was set up a short distance away, facing the CMUT. To reduce the size, weight, cost, and power consumption of conventional ultrasonic anemometers this study proposes two CMUT designs ...

A Micropower -Based Interface ASIC for a Capacitive 3-Axis Micro-Accelerometer

In this paper, a micropower interface IC for a capacitive 3-axis micro-accelerometer is presented. The IC is implemented in a 0.25m CMOS process. The fully-integrated sensor interface is based on a sensor front-end that operates mechanically in an open-loop configuration and converts the acceleration signals directly into the digital domain, thus avoiding the use of separate analog-to-digital c...

A 21.2μA -Based Interface ASIC for a Capacitive 3-Axis Micro-Accelerometer

In this paper, a micropower interface IC for a capacitive 3-axis micro-accelerometer implemented in a 0.25 -μm CMOS process is presented. The fully-integrated sensor interface consists of a sensor front-end that converts the acceleration signal into the digital domain, a decimator, a frequency reference, a clock generator for the front-end, a voltage and current reference, the required referenc...

A 62μA Interface ASIC for a Capacitive 3-Axis Micro-Accelerometer

Capacitive accelerometers [1] have advantages such as zero static bias current, the capability of high sensitivity, and excellent thermal stability, making their use in low-power applications attractive. In this paper, an interface ASIC designed for a capacitive 3-axis micro-accelerometer [2] is presented. The die area and power dissipation are reduced by using time-multiplexed sampling and dut...

A Flexible Ultrasound Transducer Array with Micro-Machined Bulk PZT

This paper proposes a novel flexible piezoelectric micro-machined ultrasound transducer, which is based on PZT and a polyimide substrate. The transducer is made on the polyimide substrate and packaged with medical polydimethylsiloxane. Instead of etching the PZT ceramic, this paper proposes a method of putting diced PZT blocks into holes on the polyimide which are pre-etched. The device works i...
