Living Kombucha Electronics with Proteinoids

mycolabadmin

Scientists created a new material by combining Kombucha cellulose with synthetic proteinoids (protein-like structures made from amino acids) to produce living electronics that can sense and process information. This hybrid material exhibits unusual electrical properties, including the ability to perform logic operations like computer circuits. The proportions of each component can be adjusted to customize the electrical behavior, opening possibilities for wearable technology and brain-inspired computing devices.

MycelioTronics: Fungal mycelium skin for sustainable electronics

mycolabadmin

Researchers have developed a new type of electronic device substrate made from fungal mycelium, the thread-like root structure of mushrooms. This material is completely biodegradable and can be processed like traditional electronic materials to create flexible circuits and batteries. The mycelium-based devices can power wireless sensors and transmit data via Bluetooth, demonstrating that sustainable electronics can perform just as well as conventional ones while being composted at the end of their life.

Organic electro-scattering antenna: Wireless and multisite probing of electrical potentials with high spatial resolution

mycolabadmin

Researchers have developed tiny organic antennas that can wirelessly detect electrical signals in liquid environments with remarkable precision. These antennas use light scattering to monitor electrical activity and can be densely packed together to simultaneously measure thousands of signals from different locations. The technology could revolutionize how scientists study heart cells, nerve cells, and other bioelectrical phenomena, potentially enabling new medical diagnostic tools and treatments.

An artificial visual neuron with multiplexed rate and time-to-first-spike coding

mycolabadmin

Scientists created an artificial neuron that mimics how biological eyes process visual information by combining two different encoding methods simultaneously. This device can fire electrical spikes at different frequencies (like how biological neurons respond to brightness) while also measuring precise timing of the first spike (which captures rapid changes). When tested with an autonomous vehicle system, this artificial neuron performed better than using either encoding method alone, suggesting it could lead to more efficient and capable robot vision systems.

Sustainable memristors from shiitake mycelium for high-frequency bioelectronics

mycolabadmin

Scientists have discovered that shiitake mushrooms can be grown into computer memory devices called memristors. These fungal memristors work similarly to brain neurons, can be dried and stored for later use, and operate reliably at high speeds. Because they use common, biodegradable mushrooms instead of rare minerals, they offer an environmentally friendly alternative for computing that could be used in spacecraft and other advanced applications.
