Light is quietly becoming the new language of brain technology. Instead of thick wires and skull-penetrating electrodes, a ...

Peripheral nerves—the network connecting the brain, spinal cord, and central nervous system to the rest of the body—transmit sensory information, control muscle movements, and regulate automatic ...

Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used ...

Abstract: Native tissues are composed of dense cellular structures embedded within an extracellular matrix (ECM) that provides essential mechanical, topographical, and biochemical cues to regulate ...

Sticking an implantable sensor to the surface of a beating heart usually requires suturing around the periphery of the sensor or copious amounts of adhesive layered between the sensor and the heart.

Brain–computer interfaces are technologies that enable direct communication between brain activity and external devices, enabling researchers to monitor and interpret brain signals in real time. These ...

" This dual capability enables a long-term, stable neural interface without harming the surrounding tissue." The in-vivo experiments in mice also validated the device's capacity to record light-evoked ...

The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself: in short, a hydrogel. Meanwhile, semiconductors—the key materials ...

A high-resolution brain interface records movement signals from the brain's surface, enabling real-time control performance similar to invasive implants without entering brain tissue. (Nanowerk ...
