Abstract
Abstract The design of Smart Biomedical Devices will be a defining element of future research in the context of intelligent medical devices for the Internet of Medical Things (IoMT). A prerequisite for serving the disposable market is the use of cost-effective electronic components and the highest reliability of the developed products in terms of biocompatibility and bioprotection. In the study, resistors, capacitors, and light-emitting diodes, different in their materials and construction forms, were examined. The selected types represented electronic components as they are commonly installed on electronic system from the segment of low-cost standard components. These were subjected to steam sterilization with up to 50 cycles, gamma sterilization, and a CCK-8 assay to test in vitro cytotoxicity. Functional failure could not be determined for any component. Gamma sterilization did not result in significant changes in resistance values, but in capacitors with barium titanate as dielectric. Non-cytotoxic electronic components could be identified. The results show that certain electronic standard components are suitable for disposable Smart Biomedical Devices.
Highlights
In recent years, the Internet of Medical Things (IoMT) has become increasingly important in all areas of medical technology [1]
In our study we examined common electronic standard components in steam sterilization up to 50 cycles, gamma sterilization with a typical dose of 25 kGy and cytotoxicity according to the requirements of the standard for the biological evaluation of medical devices DIN EN ISO 10993-5
The Surface Mounted Device (SMD) resistors were above the 70% limit, Through-Hole Technology Device (THT) resistors at the threshold
Summary
The Internet of Medical Things (IoMT) has become increasingly important in all areas of medical technology [1]. The disposable market is mainly driven by costs, which means that commercially available mass electronics are moving into the focus of interest. Passive components, such as resistors and capacitors, and active components, such as light. K. Werner et al, Cytotoxicity and Sterilization Resistance of Electronic Components for Disposable Smart Biomedical Devices — 298 emitting diodes, usually represent an almost negligibly small part of the costs of IoT and IoMT systems. In our study we examined common electronic standard components in steam sterilization up to 50 cycles, gamma sterilization with a typical dose of 25 kGy and cytotoxicity according to the requirements of the standard for the biological evaluation of medical devices DIN EN ISO 10993-5. The aim was to make statements on resistance by means of well-founded observations of the influences of the load spectrum humidity and temperature, radiation as well as toxic behavior of the electronic components
