A flexible bioelectronic bandage for accelerated repair of intestinal wounds

A flexible, biodegradable and self-powered electronic bandage is designed to deliver dual-mode electrical stimulation, which can synergistically accelerate local intestinal wound healing. This approach also shows promise for reducing postoperative complications and could have broad potential for application in other tissues and organs.

Wireless radiofrequency network of distributed microsensors

Distributed sensing of a dynamic environment is typically characterized by the sparsity of events, such as neuronal firing in the brain. Using the brain as inspiration, an event-driven communication strategy is developed that enables the efficient transmission, accurate retrieval and interpretation of sparse events across a network of thousands of wireless microsensors.

From equitable access to equitable innovation: rethinking bioengineering for global health

What does global health equity mean? In bioengineering, ‘equity’ is often interpreted as global ‘access’ to technologies, thereby neglecting wider structural inequalities. Here we suggest that concepts of equity need to be expanded to incorporate principles of equitable representation and recognition within the innovation ecosystem.
