For drone and robotic vision and navigation\, low-powe r 3-D depth sensing with robust operations against strong/weak light and v arious weather conditions is crucial. CMOS image sensor (CIS) and light de tection and ranging (LiDAR) can provide high-fidelity imaging. However\, C IS lacks depth sensing and has difficulty in low light conditions. LiDAR i s expensive with issues of dealing with strong direct interference sources . UIS\, on the other hand\, is robust in various weather and light conditi ons and is cost-effective. However\, in air channel\, it often suffers fro m long image reconstruction latency and low framerate.\n\nTo address these issues\, this talk introduces UIS ASICs for medical and drone application s. The medical UIS ASIC is designed to transmit pulse and receive echo thr ough a 36-channel 2-D piezoelectric Micromachined Ultrasound Transducer (p MUT) array. The 36-channel ASIC integrates a transmitter (TX)\, a receiver (RX)\, and an analog-to-digital converter (ADC) within the 250- μm pitch channel while consuming low-power and supporting calibration to compensat e for the process variation of the pMUT. With its small form factor\, Inte rvascular Ultrasound (IVUS) and Intracardiac Echocardiography (ICE) become s a viable application. The ASIC in 0.18- μm 1P6M Standard CMOS is verifi ed with both electrical and acoustic experiments with a 6×6 pMUT array. A lso\, the ASIC for drone applications generates 28 Vpp pulses in standard CMOS and the digital back-end (DBE) achieves 9.83M-FocalPoint/s throughput to effectively translate real-time 3-D image streaming at 24 frames/s. Wi th an 8×8 bulk piezo transducer array\, the UIS ASIC is installed on an e ntry-level consumer drone to demonstrate 7-m range detection while the dro ne is flying. The talk will conclude with interesting research directions lying ahead in UIS.\n\nSpeaker(s): Prof. Jerald Yoo\, \n\nRoom: E8\, Bldg: ETZ building\, Gloriastrasse 35\, Zurich\, Switzerland\, Switzerland\, 80 92 LOCATION:Room: E8\, Bldg: ETZ building\, Gloriastrasse 35\, Zurich\, Switze rland\, Switzerland\, 8092 ORGANIZER:tkjang@ethz.ch SEQUENCE:3 SUMMARY:Towards Monolithic Mobile Ultrasound Imaging System for Medical and Drone Applications URL;VALUE=URI:https://events.vtools.ieee.org/m/432604 X-ALT-DESC:Description: <br /><p class="FigureCaption" style="margin-left: 36.0pt\;"><span lang="EN-US" style="font-size: 11.0pt\;">Ultrasound Imagin g System (UIS) has been widely used in medical imaging with its non-invasi ve\, non-destructive monitoring nature\; but so far the UIS has large form factor\, making it difficult to integrate in mobile form factor.
