“…Though there are some examples where IPL/photonic sintering can enable processing of high-temperature inks on thermally sensitive substrates such as PET, there are many examples where the elevated temperatures produced can still negatively affect the underlying substrate, causing it to buckle, 47 deform, 42,47 and melt. 42,48 To address these challenges, Wagner et al demonstrated that the incorporation of an interfacial layer of BNNT between a silver MOD ink and PET substrate has several benefits that enhance the electrical properties of silver traces produced by IPL sintering.…”

Technology-based industries are constantly seeking materials and methods to fabricate compact, high-performance, and increasingly more complex printed electronic devices, fostering research in advanced conductive inks and processing techniques. Metal−organic decomposition (MOD) inks are a class of conductive inks based on molecular metal precursors that decompose into metallic features once printed, imparting them with unique attributes that distinguish them from particle-based inks. This Spotlight on Applications summarizes recent progress in understanding the chemistry, rheology, and printability of MOD inks that enable them to be printed, processed, and used with material substrates in unconventional ways. Their unique properties and capabilities are being leveraged to advance the field of printed electronics, from their use in 2.5D and 3D surfaces, wearables, and fine line printing and thus broadening the form factors and improving properties of devices used in the medial, automotive and aerospace industries.

“…Angel et al [60] proposed a new curing method for parts printed on a uniaxial double sloped 3D surface by photonic sintering. Hawasli et al [61] also demonstrated that the resistances of 3D printed traces can be lowered by using a combination of photonic sintering and copper electroplating.…”

2D coil design limits the use of wireless power transfer (WPT) in many products with freeform outer shapes. In this paper, enabled by 3D printed electronics, we propose a systematic approach to design and fabricate 3D coils for WPT. Based on the circular spiral and rectangular spiral patterns, 3D receiver and transmitter coils can be generated on an arbitrarily selected region of a product and its offset, respectively. Mathematical models are proposed to estimate the self-inductance and the mutual-inductance of the 3D arbitrarily shaped coils for 3D WPT. This leads to a new design approach of a 3D WPT system. Several sets of 3D printed WPT systems were designed, simulated, and prototyped to demonstrate the effectiveness of the proposed design approach as well as the mathematical models. The calculation speed of the proposed mathematical models is 30 times faster than the simulation, and compared with the measurement results, the calculation results have mean absolute errors of 2.63% and 4.45% regarding the self-and the mutualinductance, where the simulation results have mean absolute errors of 1.20% and 2.38%, respectively. Measurements also indicate that with a 5V input, the prototypes are able to deliver 1-watt power at an efficiency ranging between 20.9% and 25.3%. It was concluded that the proposed approach is feasible and promising for designing and manufacturing WPT using 3D printed electronics.INDEX TERMS 3D coil, WPT, IPT, 3D printed electronics, design.
