A power-efficient architecture is proposed to keep the internal circuitry operating at 0.4V while regulating the output voltage at 1V using switched-capacitor DC-DC converters and a hysteresis controller. Peak efficiency of 86% is achieved at 0.39V input voltage and 1.34\u03bcW of output power with 220nW of internal average power consumption. Integrated operation with lactate biofuel cells is demonstrated.", "doi": "10.1109/cicc48029.2020.9075912", "isbn": "9781728160313", "publisher": "IEEE", "place_of_publication": "Piscataway, NJ", "publication_date": "2020-03", "pages": "1-4" }, { "id": "authors:0x02h-n5047", "collection": "authors", "collection_id": "0x02h-n5047", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20200220-134102759", "type": "book_section", "title": "Photoacoustic computed tomography guided microrobots for targeted navigation in intestines in vivo", "book_title": "Photons Plus Ultrasound: Imaging and Sensing 2020", "author": [ { "family_name": "Li", "given_name": "Lei", "orcid": "0000-0001-6164-2646", "clpid": "Li-Lei" }, { "family_name": "Wu", "given_name": "Zhiguang", "clpid": "Wu-Zhiguang" }, { "family_name": "Yang", "given_name": "Yiran", "orcid": "0000-0001-8770-8746", "clpid": "Yang-Yiran" }, { "family_name": "Hu", "given_name": "Peng", "orcid": "0000-0002-2933-1239", "clpid": "Hu-Peng" }, { "family_name": "Gao", "given_name": "Wei", "orcid": "0000-0002-8503-4562", "clpid": "Gao-Wei" }, { "family_name": "Wang", "given_name": "Lihong V.", "orcid": "0000-0001-9783-4383", "clpid": "Wang-Lihong-V" } ], "contributor": [ { "family_name": "Oraevsky", "given_name": "Alexander A.", "clpid": "Oraevsky-A-A" }, { "family_name": "Wang", "given_name": "Lihong V.", "clpid": "Wang-Lihong-V" } ], "abstract": "Tremendous progress in synthetic micro/nanomotors has been made for potential biomedical applications.

The micromotors enveloped in microcapsules exhibit efficient propulsion in various biofluids once released. PACT has visualized the migration of micromotor capsules toward the targeted regions in real time in vivo. The integration of the developed microrobotic system and PACT enables deep imaging and precise control of the micromotors in vivo.", "doi": "10.1117/12.2547559", "isbn": "9781510632431", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "publication_date": "2020-02-17", "pages": "Art.
