Researchers from the University of Cambridge have made a surprising discovery that challenges conventional wisdom in the field of electrochemical devices. They found that in conjugated polymer electrodes, the movement of "holes" (empty spaces for electrons) can be the limiting factor in the charging process, contrary to the belief that ions are slower. By manipulating the material's structure, scientists can regulate the movement of holes and improve charging efficiency. This breakthrough has significant implications for bioelectronics, energy storage, and brain-like computing, paving the way for the development of cutting-edge medical devices, wearable technologies, and more efficient energy storage solutions.

Researchers at Lund University and Gothenburg University have developed temporary, organic electrodes that can be injected into the body using a needle, eliminating the need for surgery. The electrodes self-organize into a conducting structure and integrate with the body's cells, providing a minimally invasive approach to electrotherapy. The electrodes break down and are excreted from the body after treatment, making them suitable for non-chronic diseases that are difficult to treat. The new method opens up possibilities for more effective therapies in areas such as cancer and nerve injuries.

Researchers have successfully mapped the electrical signals that trigger the deadly movement of Venus flytraps for the first time. Using thin-film sensors and electrodes, the team measured and recorded the electrical impulses generated by the plant's sensory hairs. The study revealed that the signals propagate at a constant speed from tripped sensory hairs, triggering the trap to close. Surprisingly, the researchers also found spontaneous electrical signals originating from unstimulated hairs. Further research is needed to understand the function of these signals and how electrical impulses propagate in plants. Decoding these signals could provide insights into plant functioning and stress responses.

Researchers at Columbia Engineering have developed the first fully organic bioelectronic device that can acquire and transmit neurophysiologic brain signals while providing power for device operation. The device, about 100 times smaller than a human hair, is based on an organic transistor architecture that is biocompatible, flexible, and stable in the long term. It incorporates a vertical channel and a miniaturized water conduit, demonstrating high electrical performance, low-voltage operation, and long-term stability. The device has the potential to revolutionize medical implants and improve diagnostics and treatment for patients with neurological disorders.

Researchers at Chalmers University of Technology and the University of Freiburg have developed a method using electric stimulation to speed up the healing process of wounds on cultured skin cells, making them heal three times faster. The method could be a game changer for diabetic and elderly people who often suffer greatly from wounds that won't heal. The researchers recently received a large grant to continue their research and develop wound healing products for consumers on the market. They are also looking at how different skin cells interact during stimulation to adapt the stimulation based on the individual wound.

British scientists have developed a brain implant that can restore arm and leg movements by boosting connections between neurons and the paralyzed limbs. The device combines flexible electronics and human stem cells to better integrate with the nerve and drive limb function. The researchers found that the device integrated with the host’s body and the formation of scar tissue was prevented. While extensive research and testing will be needed before it can be used in humans, the device is a promising development for amputees or those who’ve lost function in limbs.

Researchers from the University of Cambridge have developed a neural implant that combines flexible electronics and human stem cells to improve the connection between the brain and paralyzed limbs. The device prevents scar tissue formation and improves functionality and sensitivity. While the device has only been tested on rats, it shows promise for amputees or those who have lost function of a limb or limbs. The researchers are now working to optimize the devices and improve their scalability.
