To facilitate this transition to a higher level of healthcare, the medical sector has been developing devices that will allow for continuous health monitoring and even therapy while being portable and easily manageable remotely. For example, there are now smartwatches that can help in detecting cardiac irregularities and diabetes sensors for glucose monitoring, neural implants for movement restoration and restoration of hearing ability via cochlear implants, etc.
This transformation is due to the convergence of several factors such as small size, flexibility, low power consumption of integrated circuits, artificial intelligence, high-speed wireless communication, MEMS, and many others. Therefore, with the shift of paradigm in healthcare to patient-oriented continuous monitoring, bioelectronics becomes one of the most active industries of electronics.
Understanding Bioelectronics
Bioelectronics involves a multidisciplinary approach that integrates electrical engineering, electronics, biology, materials science, and medicine to create devices that interact with biological tissues and physiological processes.
In contrast to the traditional medical devices that observe or measure the biological activity, bioelectronics creates a bidirectional interaction between the device and the body. Bioelectronics are capable of sensing electrical, chemical, and mechanical signaling of the biological systems and, in some cases, provide specific electrical stimulation of physiological processes.
Bioelectronics have a wide range of applications in medicine and include areas such as heart function control, neurology, diabetic treatment, rehabilitation, ophthalmology, deafness treatment, pain control, pharmacological applications, and tissue regeneration.
The emergence of flexible electronics and biocompatible materials greatly contributed to the development of devices that are in harmony with natural contours of the body.
