A hemodynamics-driven magnetoelastic vascular graft (MVG) has been developed, and its biosafety and functionalities were successfully validated in vivo in rat and pig. The MVG restores blood flow and enables wireless, real-time and continuous stenosis diagnosis, and has clinical potential for improving the management of human vascular disease.

Engineered blood vessels harness artificial intelligence (AI) and magnetoelasticity to continuously monitor blood flow and stenosis in real time.

Wearable neuromorphic optoelectronics require advanced dynamic perception and multifunctional integration. Here, authors develop intrinsically stretchable neuromorphic visual adaptive transistors with simpler structure and improved performance with adaptive time down to 0.4 s.

Achieving multiple functions in a self-sustained human-machine interface remains challenging. Bai et al. show a hydrogel-based e-skin that integrates thermogalvanic, piezoionic, and diffusion mechanisms for self-powered simultaneous sensing of skin temperature, arterial pulsation, and sweat secretion.

A vascular graft enables wireless, real-time and continuous stenosis diagnosis and management.

The researchers exploit lattice-anchoring-enhanced dynamic repair in organic–inorganic hybrid perovskites to demonstrate a single-crystal detector with a sensitivity of 165.6 μC mGy⁻¹ cm⁻³ and radiation stability under high-fluence 6-MeV X-rays (6.4 × 10¹¹ photons cm⁻²) and 1.2-MeV electrons (6 × 10¹⁶ electrons cm⁻²). The findings may have implications for diverse applications, including radiation therapy, astronomy and nuclear technology.

Di et al. report a dual-band infrared photodetector employing size-engineered PbS quantum dots as spectrally selective absorbers in a unipolar barrier configuration, which can switch between near- and short-wave infrared region.

The authors report an omnidirectional, strain-invariant MXene-based electronic system enabled by microgrid stiffness engineering, maintaining less than 5% performance variation under 40% tensile strain for battery-free physiological and blood pressure monitoring.

Soft bioelectronics promise seamless human–machine integration but typically struggle to maintain reliable functionalities under long-term exposure to the body’s dynamic environment. Identifying the full spectrum of failure modes, while implementing multidimensional strategies to enhancing long-term stability, is key to achieving clinical-grade stability.
