“…For long-term device function, encapsulation and biocompatibility are essential factors to consider. 40,41 These devices are encapsulated in parylene C to provide a biofluid barrier and polydimethylsiloxane (PDMS) to match Young's modulus of the device surface to that of the surrounding tissue, thereby minimizing impact of the implantation procedure to surrounding tissue. 23,42−44 The device utilizes MRC at 13.56 MHz for WPT 3,23,[25][26][27][28]45,46 and features a center-tapped antenna structure for the conversion of harvested alternating current (AC) to direct current (DC) with negative and positive potential for supplying reference voltages to the sensor and powering digital electronic components, respectively.…”

“…[99][100][101] Although 3D MEA has the advantage of high measurement reliability compared with 2D MEA, it is still limited considering the damage induced to the soft organoids by the protruding of rigid electrodes. [102] This mechanical mismatch between the organoids and the device is expected to be overcome with the utilization of soft materials or the structural engineering of the devices.…”

“…[6,7] Implantable sensors have been used for real-time in vivo detection of biomarkers, useful for managing chronic diseases, improving personalized drug therapy, and treating neurological disorders. [8][9][10][11] For optimized practical performance, wearable and implantable sensors should be fabricated with materials that possess a combination of characteristics, including stretchability, conductivity, fatigue resistance, and biocompatibility. Hitherto, materials that have been investigated to prepare wearable and implantable sensors include metals, metal nanoparticles, conductive polymers, carbon materials, and hydrogels.…”
