Self-Sensing Actuators Based on Ferromagnetic Shape Memory Alloys [PDF]
, 2022 S.212-215Ferromagnetic shape memory alloys (FSMA) exhibit a strong magneto-mechanical coupling, which motivates their application in electro-mechanical actuators. The significant magnetic anisotropy causing the coupling can also be used for sensing.

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
