Wireless technology products and services play a significant role in our everyday lives. Great advances in design features have improved the accessibility and utility of these technologies for older adults and people with disabilities. Yet, there is still opportunity to ensure upcoming designers of wireless technologies consider how their design helps or hinders their product's potential users. In this paper, we describe the evolution of a series of half-day participatory design workshops intended to expose student designers to real-world problem-solving alongside experts in the fields of aging and disability services and end users. Workshop attendees rapidly worked through an inclusive design process identifying and defining problems, considering the design requirements to meet the needs of various individuals, and finally designing and refining concepts to solve those problems. We describe the design of the workshops, iterations intended to improve on the experience, and our recommendations for conducting similar workshops.

The bidirectional interactions between metamaterials and artificial intelligence have recently attracted immense interest to motivate scientists to revisit respective communities, giving rise to the proliferation of intelligent metamaterials and metamaterials intelligence. Owning to the strong nonlinear fitting and generalization ability, artificial intelligence is poised to serve as a materials-savvy surrogate electromagnetic simulator and a high-speed computing nucleus that drives numerous self-driving metamaterial applications, such as invisibility cloak, imaging, detection, and wireless communication. In turn, metamaterials create a versatile electromagnetic manipulator for wave-based analogue computing to be complementary with conventional electronic computing.

Cancer cells possess distinct bioelectrical properties, yet therapies leveraging these characteristics remain underexplored. Herein, we introduce an innovative nanobioelectronic system combining a piezoelectric barium titanate nanoparticle core with a conducting poly(3,4-ethylenedioxythiophene) shell (BTO@PEDOT NPs), designed to modulate cancer cell bioelectricity through noninvasive, wireless stimulation. Our hypothesis is that acting as nanoantennas, BTO@PEDOT NPs convert mechanical inputs provided by ultrasound (US) into electrical signals, capable of interfering with the bioelectronic circuitry of two human breast cancer cell lines, MCF-7 and MDA-MB-231.

Traditional sensors struggle in complex human environments, particularly with humidity and strain detection requiring high sensitivity and robust anti-interference. This work introduces a flexible, miniaturized, low-cost dual-mode sensor that combines a novel resonator structure with a chemically modified conducting polymer, enabling simultaneous strain and humidity detection alongside high anti-interference performance sensitivity and wireless transmission.

They are a vital technology for terahertz wireless communication and radar detection systems. Compared with 1-bit coding metasurfaces, 2-bit coding metasurfaces offer significant advantages such as single beam steering and reduced quantization errors.
View Article and Find Full Text PDFBroadband minimalist wireless base stations without energy-consuming electrical power amplifiers are the rosy scenario of the next-generation wireless communication systems. High-power radio-over-fiber (RoF) links, which are featured by large operation bandwidths, are regarded as the supporting technology for realizing such a vision. Nevertheless, the severe signal-to-noise ratio (SNR) deterioration induced by the second Brillouin scattering in high-power and long-distance RoF links must be first solved.
