Electronic stethoscopes are able to offer signal amplification and other benefits over traditional stethoscopes. However, many electronic stethoscopes rely on a personal computer for their signal processing, which reduces portability and requires a relatively large amount of power. This paper presents a low power, portable electronic stethoscope system that is based on a signal processing approach using an over-sampled filterbank. This system is implemented on an ultra-low resource DSP system. The stethoscope incorporates multiple filtering modes as well as audio record and playback (full and half speed) functionality.

This review covers advancements in biosensing, biophotovoltaics, and photobiomodulation, focusing on the synergistic use of light, biomaterials, cells or tissues, interfaced with photosensitive dye-sensitized, perovskite, and conjugated polymer organic semiconductors or nanoparticles. Integration of semiconductor and biological systems, using non-invasive light-probes or -stimuli for both sensing and controlling biological behavior, has led to groundbreaking applications like artificial retinas. From fusion of photovoltaics and biology, a new research field emerges: photovoltaic bioelectronics.
