Current earphone designs follow a universal approach, which might fit average body shapes comfortably but lead to discomfort for others. Leveraging technologies like AI, simulations, and digital models enables efficient creation of personalized products at scale (Sony, 2018). With the development of new AM techniques, printing options are...

This thesis presents a practical topology for achieving highly efficient dual-side wireless power transfer (WPT). Traditional WPT systems with a diode rectifier on the secondary side lack flexibility in load matching, requiring the integration of an additional dc/dc converter at the back end. However, this approach leads to increased power...

Shared mobility has been present longer than you imagine. In the 1940s, the idea of sharing bicycles started in Switzerland. However, the modern manifestation only became popular about a decade ago, but since then, the market for sharing vehicles has grown significantly. In recent years, different ridesharing services have been popping up. In...

Wireless charging has the potential to speed up the transition to electric vehicles (EVs) because it is intrinsically a user-friendly technology. Furthermore, it is essential when charging completely autonomous EVs, and it enables the charging of EVs in motion without using overhead cables. The most common technology used in EV wireless charging...

One of the major challenges associated with e-textiles is the connection between flexible fabric-integrated wires and rigid electronics. This work aims to increase the user experience and mechanical reliability of these connections by foregoing conventional galvanic connections in favor of inductively coupled coils. The new design allows for...

Light-duty electric vehicles (EVs) typically have a rated voltage of either 400 or 800 V. Especially when considering public parking infrastructures or owners with multiple EVs, e.g., car rental companies, EV wireless chargers must efficiently deliver electric power to both battery options. For this purpose, this article proposes an advanced...

In this article, we propose a reconfigurable regulating rectifier with a wide operational range for wireless power transfer. The proposed three-mode rectifier achieves a broad range voltage regulation without global loop control to minimize the chip area occupation. Compared with previous work, more working modes and greater voltage gain...

Testing the aerodynamics of micro-UAVs (mUAVs) and nano-UAVs (nUAVs) without actually flying is highly challenging. To address this issue, we introduce Open Gimbal, a specially designed 3 degrees of freedom (DoF) platform that caters to the unique requirements of mUAVs and nUAVs. This platform allows for unrestricted and free rotational...
