Abstract
Bioresorbable electronic devices and/or systems are of great appeal in the field of biomedical engineering due to their unique characteristics that can be dissolved and resorbed after a predefined period, thus eliminating the costs and risks associated with the secondary surgery for retrieval. Among them, passive electronic components or systems are attractive for the clear structure design, simple fabrication process, and ease of data extraction. This work reviews the recent progress on bioresorbable passive electronic devices and systems, with an emphasis on their applications in biomedical engineering. Materials strategies, device architectures, integration approaches, and applications of bioresorbable passive devices are discussed. Furthermore, this work also overviews wireless passive systems fabricated with the combination of various passive components for vital sign monitoring, drug delivering, and nerve regeneration. Finally, we conclude with some perspectives on future fundamental studies, application opportunities, and remaining challenges of bioresorbable passive electronics.
Highlights
Transient electronics form the basis for classes of bioresorbable electronic devices or systems that undergo complete physical disintegration and chemical dissolution after a predefined operation period
The capacitive bioresorbable strain sensor layer similar to their previous work, a top electrode encapsulated by poly(lactic acid) (PLLA), and a bottom contains two neighboring bottom comb electrodes that could slide relatively to change the comb electrode supporting on a PLLA substrate
We have summarized the recent progress on materials, device architectures, and integration strategies of bioresorbable passive electronics, with emphases on their applications in biomedical engineering
Summary
Transient electronics form the basis for classes of bioresorbable electronic devices or systems that undergo complete physical disintegration and chemical dissolution after a predefined operation period. Inductors are able to store are widely adopted to construct a capacitor-types sensor for the detection of regional body the magnetic energy induced by the electric current passing through them They can be temperature [17], pressure [18], or humidity [19]. Examples based on bioresorbable resistors, capacitors, and inductors, such section, we will summarize the material strategies for the construction of bioresorbable as biodegradable pressure sensors, temperature sensors, pH sensors, bioelectrodes, power passive systems, devices. We conclude with some perspectives on future fundamental studies, application opportunities and remain challenges of bioresorbable passive electronics
