“…Differently from acoustic angiography, IVUS and ICE are more invasive procedures as they require the insertion of a catheter, at whose tip the transducer is mounted. Traditional IVUS and ICE systems relied on a single rotating transducer [81]; however the mechanical rotation of the tip introduces rotation artefacts, and the rotation mechanism is complex to integrate with the catheter: for these reasons solid-state CMUT phased arrays [72], [82]- [85], operating at 20-40MHz (IVUS) and 8 MHz (ICE) center frequencies, were implemented as an alternative. The traditional and MUT-based IVUS/ICE catheter, employing a solidstate phased array, are illustrated in Fig.…”

“…Given the small size of the catheter, the miniaturization and integration of the transducer and its electronics, together with the minimization of the number of connections, represent the most critical challenge: for this reason, CMUTs are generally preferred over PMUTs as they enable better miniaturization. The CMUT and its application-specific integrated circuit (ASIC) are connected together by means of wirebonding [82], [83] or using a Through-Silicon-Via process [87]; parylene and silicone-like materials are used for coating the wires to ensure electrical insulation [82], [83] and flexible structures, such as the ones enabled by the so-called Flexto-Rigid (F2R) process, are used to fit the catheter tip form factor [83], [88]. Although it is possible to delocalize some of the circuitry (e.g.…”

Piezoelectric Micromachined Ultrasonic Transducers (PMUT) and Capacitive Micromachined Ultrasonic Transducers (CMUT) have seen great developments in recent years, both in terms of performance and scope of applications within the biomedical ultrasound domain. This paper presents a review of the state-of-the-art of PMUT and CMUT technologies, focusing on their principle of operation, microfabrication techniques and use in different biomedical imaging and therapeutic applications. The advantages and drawbacks of PMUT and CMUT technologies in comparison with conventional bulk transducers are highlighted, the trade-offs among PMUTs and CMUTs are discussed, and their relevance in the current landscape of medical diagnostics and therapeutic uses is outlined, thus providing a clear overview of these promising technologies for the present and the next generation biomedical ultrasound applications.

“…From the presented results in these works, there are some aspects to highlight. The first one is related to the low operating frequency range, which despite the high sensitivity values achieved, is not suitable to characterize medical ultrasound devices (operating in MHz frequencies, for instance, the frequency of lithotripsy ranges from 0.2 MHz to 0.9 MHz [17], for IVUS the operation frequency is in the range of 10's MHz [18]). The second aspect considers the conditioning circuitry where, like in all commercialized hydrophones, the needed preamplification is in a separated substrate (chip or package), requiring electrical connections between hydrophone and preamplifier, bigger overall sizes, affecting the performance of the received acoustic signals (degraded signal due to a large parasitic capacitance) and increasing the overall cost of the hydrophone system.…”

This work presents a minute single chip PMUTs-on-CMOS-based hydrophone with high receiving sensitivities and low noise. The system is based on three different Sc9.5%Al90.5%N PMUTs geometries, (a) square with an 80 m side, (b) rectangular with a dimension of 60 m x 40 m, and (c) annular with an outer diameter of 80 m which allows to carry out acoustic measurements at very close distances from the transducer under test. Each device is monolithically integrated with a CMOS LNA amplifier with a gain of 25 dB. The first hydrophone prototype was validated in water where two commercial hydrophones from ONDA (HGL-0085 and HNC-0200) were used as references. The experimental results give mean receiving sensitivities of -234 dB re 1V/Pa (equivalent to 1.9 V/MPa), -234.6 dB re 1V/Pa (equivalent to 1.86 V/MPa) and -238.3 dB re 1V/Pa (equivalent to 1.22 V/MPa) for (a), (b) and (c), respectively. These results demonstrate the high performance of the presented PMUTs-on-CMOS to be used in a miniaturized hydrophone for characterizing highfrequency ultrasound transducers.

“…Moreover, a LiDAR system may require a power-hungry transmitter (TX), such as a >40-W pulsed laser diode [6], [7]; and it is also an expensive solution, making it less attractive for consumer-grade drone applications. Ultrasound imaging [10], [11], [12], [13], [14], [15], [16], [17], [18], on the other hand, can provide low-power 3-D-depth information and works well even in complex lighting conditions (bright/dark) as well as in rainy/foggy weather. Of course, this comes at the cost of lower spatial resolution when compared to CIS or LiDAR, but this is not a major issue in drone navigation.…”

“…Of course, this comes at the cost of lower spatial resolution when compared to CIS or LiDAR, but this is not a major issue in drone navigation. Previously, UISs [10], [11], [12], [13], [14] shown successful results for biomedical applications. Due to the slow sound speed (343 m/s in air compared to 1540 m/s in tissue) and long detection range compared to in vivo, air-channel ultrasound imaging [15], [16], [17], [18] possesses a different challenge in how to achieve adequate framerate with a limited number of transmissions.…”

For drone vision and navigation, low-power 1 3-D depth sensing with robust operations against strong/weak 2 light and various weather conditions is crucial. CMOS image 3 sensor (CIS) and light detection and ranging (LiDAR) can 4 provide high-fidelity imaging. However, CIS lacks depth 5 sensing and has difficulty in low light conditions. LiDAR is 6 expensive with issues of dealing with strong direct interference 7 sources. Ultrasound imaging system (UIS), on the other hand, 8 is robust in various weather and light conditions and is 9 cost-effective. However, in air channel, it often suffers from long 10 image reconstruction latency and low framerate. To address 11 these issues, we present a UIS application-specific integrated 12 circuit (ASIC) that adopts the one-shot transmitter (TX) and 13 on-chip per-voxel receiver (RX) beamfocusing (PV-RXBF) 14 image reconstruction scheme. The ASIC adopts the designs of 15 fully differential charge-reuse high-voltage TX (FDCR-HVTX), 16 digital back-end (DBE), and an on-chip power management unit 17 (PMU). FDCR-HVTX generates 28 V pp pulses and reduces the 18 average power consumption by 25% by charge reuse (CR). The 19 DBE achieves 7.76-µs processing latency and 9.83M-FocalPoint/s 20 throughput to effectively translate real-time 3-D image streaming 21 at 24 frames/s. A prototype UIS, with an 8 × 8 bulk piezo 22 transducer array, is assembled with the proposed ASIC and 23 a wireless data transmission module [field-programmable gate 24 array (FPGA) + ESP32] on an entry-level consumer drone, 25 and the real-time wireless 3-D image streaming at 24 frames/s 26 with a range of 7 m is verified while the drone is flying.
