Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites
Advanced Materials Technologies, EarlyView.Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

Advanced Materials Technologies, EarlyView.An AlON interfacial layer is engineered within an AlN switching layer to enable transparent RRAM with four stable resistance states. The device achieves low‐voltage multilevel switching and a high HRS, allowing precise grayscale modulation and preventing light leakage in micro‐LEDs operated at VDD = 2.7 V.

Advanced Materials Technologies, EarlyView.The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess

Fully Printed Electrocaloric Heat Pump
Advanced Materials Technologies, EarlyView.A system based on a flexible printed PEDOT:PSS/P(VDF‐TrFE‐CFE) electrocaloric membrane. The membrane periodically alternates between the cold and hot sides following its electrocaloric cycle and successfully generates a temperature difference. The entire fabrication process is industrially scalable, cost‐effective, and based on widely accessible ...
