For SBSP to be feasible, the satellites need to be lightweight so they can be launched in a cost-effective way and flexible so they can fit inside payload fairings .
The SPPD-1 components are unsealed, meaning they are exposed to the extreme temperature variations of space. Beyond demonstrating that power transmitters can survive being launched into space, the experiment has provided useful feedback to SSPP engineers. The demonstrator has no moving parts and relies on constructive and destructive interference between transmission antennas to shift the focus and direction of the beamed energy. These antennas are clustered in groups of 16, each driven by a custom-made flexible integrated circuit chip.
The inside of the space-based Microwave Array for Power-transfer Low-orbit Experiment which emits collected energy across empty space using an array of transmitters to two receivers to illuminate an LED. The team is now assessing the performance of individual system elements by testing the interference patterns of smaller groups and measuring the difference between combinations. This process could take up to six months, giving the team ample time to detect irregularities and develop solutions to inform the next generation of solar satellites., a 1.8 x 1.

Wearable energy harvesting-storage hybrid textiles as on-body self-charging power systemsThe rapid development of wearable electronics requires its energy supply part to be flexible, wearable, integratable and sustainable. However, some of the energy supply units cannot meet these requirements at the same time, and there is also a capacity limitation of the energy storage units, and the development of sustainable wearable self-charging power supplies is crucial. Here, we report a wearable sustainable energy harvesting-storage hybrid self-charging power textile. The power textile consists of a coaxial fiber-shaped polylactic acid/reduced graphene oxide/polypyrrole (PLA-rGO-PPy) triboelectric nanogenerator (fiber-TENG) that can harvest low-frequency and irregular energy during human motion as a power generation unit, and a novel coaxial fiber-shaped supercapacitor (fiber-SC) prepared by functionalized loading of a wet-spinning graphene oxide fiber as an energy storage unit. The fiber-TENG is flexible, knittable, wearable and adaptable for integration with various portable electronics. The coaxial fiber-SC has high volumetric energy density and good cycling stability. The fiber-TENG and fiber-SC are flexible yarn structures for wearable continuous human movement energy harvesting and storage as on-body self-charging power systems, with light-weight, ease of preparation, great portability and wide applicability. The integrated power textile can provide an efficient route for sustainable working of wearable electronics.
