Eco-friendly and Biodegradable Electrochromic Display

Discover the future of sustainable electronics with our fully biodegradable electrochromic display! ???? This innovative display showcases signals from biodegradable devices like UV sensors and electrochemical transistors, all while operating at low voltage with enhanced stability. Crafted using a tungsten nanomesh and PLGA substrate, it ensures minimal environmental impact and degrades naturally in phosphate-buffered saline or soil under mild conditions. Say goodbye to electronic waste and hello to eco-friendly technology!

Biodegradable Ultra-Sensitive Strain Sensor: Real-Time Vascular Monitoring

An Ultra-sensitive biodegradable crack-based strain sensor (GF 1355 at 1.5% strain) was developed for real-time micro-deformation detection. It combines a Mo layer, MoO₃ adhesion layer, and PCL substrate, with a hybrid encapsulation layer (C-wax, B-wax, PBAT) for enhanced water resistance and flexibility. In vivo tests confirmed its ability to monitor vascular pulsation for up to three days.

Biodegradable, Self-deployable Electronic Tent for Brain Cortex Interfacing

We introduce a biodegradable, self-deploying tent electrode for brain cortex interfacing. It integrates with multiplexing arrays and a wireless module for near-field communication. Delivered via a syringe through a small hole, it expands to cover 200 times its original size. The electrode naturally decomposes in the body, avoiding the need for removal surgery. In vivo tests demonstrate its effectiveness in stimulating large cortical activity populations.
