#### **1. Introduction**

The development of new sensing technologies, biomaterials, microelectronic devices, microfluidic systems and micro-electro-mechanical systems (MEMs) etc., opens the window to new biomedical circuits and system opportunities to measure "better", and to develop "alternative" methods to find relevant information for physician and biologist teams, in applications such as diagnosis, therapy, clinical tests and bio-signal monitoring. However, the accomplishment of new medical equipment for specific tests in the health field poses significant challenges regarding the electronic circuits and systems needed, whose performance is vital for proper and accurate data acquisition tasks.

#### **2. Design and Application of Biomedical Circuits and Systems**

This Special Issue is devoted mainly to incorporating proposals of bio-sensing signals based on new circuits and system approaches. In general, it is focused on new bio-signal analog front-end (AFE) circuits; the development of specific circuits for known and new sensor/sensing approaches; circuits for biomedical signal processing; low-voltage and low-power (LV/LP) circuits and its application to implantable and wearable devices; circuits and systems for clinical applications; circuits for sensing/actuation in MEM systems, lab-on-a-chip (LoC), micro-total-analysis systems (uTAS); cell assays and manipulation, etc. Main topics of interest are well described by the Special Issue keywords (but not limited to):


In the present Special Issue, twelve papers have been successfully incorporated. We hope you enjoy reading this Special Issue and are inspired to address the technological challenges to help the medical industry and biologists to increase the human quality of life, which is the main objective. These are the contribution papers:


We are conscious about the very wide scope of biomedical circuits and systems applications, and that our contribution it is only a grain of sand more, but we expect to be it useful for knowledge progress in the field.

#### **3. Conclusions**

Biomedical engineering is today one of the most important research fields in the world. This fact is parallel with the health challenges surrounding the improvement of human health as one of the main vehicles to increase the quality of life. The maturity of many technologies, such as microelectronic, biomaterial, microfluidic, together with progress in the biology and medicine fields, develop alternative solutions for medical evaluation, diagnosis, therapy and research in general, opening the opportunity for new medical devices, e.g., lab-on-a-chip, wearable technology, and implants. The biomedical electronic industry supports the development of many of these new devices, as the main technologies for bio-signal acquisition, processing, and communication. In this Special Issue contribution, we present some significant contributions for biomedical applications, which, of course, should be fulfilled and improved by future contributions.
