Using an "organ-on-a-chip" device, scientists have found that heart tissues beat half as strongly on the International Space Station as they do on Earth.

Their work, published in the journal Small, could pave the way for new types of medical implants and interfaces that get up close and personal with our...

Thirty-year-old Noland Arbaugh says the Neuralink chip has let him "reconnect with the world"

An electrode inspired by soft robotics could provide less invasive brain-machine interfaces

In a paper published by the research team of Ali Hafezi-Moghadam, MD, Ph.D. at the Brigham and Women's Hospital (BWH), a founding member of Mass General Brigham, authors introduced a biodegradable fluorescent nanoprobe to detect diabetic retinopathy (DR) in its early molecular stage.

A flexible, conductive membrane that can pass sensory information to the brain and muscles is a step towards artificial skin

Synthetic hydrogels show great promise in tissue repair, drug delivery, medical implants and many other applications. Hydrogels functionalized with electrically conductive components can be used in bioelectronic devices for cardiac or neural interfaces, for applications such as neural prosthetics, cardiac patches and electronic skin.

Researchers at two Swedish universities recently unveiled the world's first electrical transistor built from conductive wood. While it performs nowhere near as well as modern silicon transistors,...

Scientists at the University of Massachusetts Amherst recently announced the invention of a nanowire, 10,000 times thinner than a human hair, which can be cheaply grown by common bacteria and can be tuned to "smell" a vast array of chemical tracers—including those given off by people afflicted with different medical conditions, such as asthma and kidney disease.

Efficient, low-cost transistors have a wide range of applications, including biomedical sensing. A multidisciplinary Northwestern University research team has created a groundbreaking transistor that is expected to be optimal for bioelectronics that are high-performance, lightweight, and flexible.

Engineers have taken their transient pacemaker and integrated it into a coordinated network of four soft, flexible, wireless wearable sensors and control units placed on different anatomically relevant locations on the body. The sensors communicate with each other to continuously monitor the body's various physiological functions, including body temperature, oxygen levels, respiration, muscle tone, physical…

A wireless neurostimulator a little bigger than a grain of rice can be put in place alongside blood vessels to treat neurological diseases and chronic pain.

In recent years, deadly infectious diseases, including Ebola and COVID-19, have emerged to cause widespread human devastation. Although researchers have developed a range of sophisticated methods to detect such infections, existing diagnostics face many limitations.

Cambridge University said its researchers have developed an electric-eel-inspired, jelly-like, battery for use in wearable devices and potentially for brain implants to treat neurological conditions.

Purdue University researchers have unveiled biosensor technology aimed at transforming agricultural practices by swiftly identifying contamination risks

Semiconductor hydrogels enable active bioelectronics

Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and techniques. But, because of their intimate contact and interactions with living tissues, selection of the right material for performance and biocompatibility is crucial. In recent times,…

Chemical engineer Zhenan Bao strives to re-create nature's ultimate electronic system.

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three…
