Sun sensors instrument measure the direction of the sun relative to the spacecraft by converting the amount of light energy into an electrical measurement. In this paper, we present a novel geometry, called 3D shape, of sun sensor array that contains three structures: pyramidal structure in the top, cube structure in the middle and inverted pyramidal structure in the bottom. In fact, our aim is to achieve the field of view of sun sensor by selecting an appropriate tilt angle of the Ambient Light sensors (ALS). To validate our 3D shape, we have developed a mathematical model allowing calculus of solar vector orientation in the sun sensor coordinates. Simulation results show the advantages of the proposed configuration compared with, well used, regular pyramidal shape.
this paper deals with design and comparison of different shaped MEMS pressure sensors. there are many components to note down the deflection of pressure but this research work has selected to design a piezoelectric pr...

New wearable technologies come with high requirements for miniaturization and flexibility, which are usually restricted by rigid batteries. Capacitive power transfer and communication, employing the human body as a conductive medium enables energy-efficient communication and even the possibility to achieve battery-lesswearable sensors distributed on the body. this work presents as a proof-of-concept a complete system consisting of a custom-designed on-body transmitter and battery-less receiver and evaluates the power transmitted and the range achieved. We demonstrate the applicability of our prototype to a real-life scenario as a glucose level tracker even in realistic non-perfect grounding conditions. the realized design offers a power transmission of up to 2.5mW at distances of 15 cm and 5.5 mu W at 125 cm, showing the possibility of battery-less on-body edge computing applications.
this paper focuses on the stability and economic operation challenges faced by the port power grid after integrating distributed renewable energy and shore power systems, and conducts research on reactive power distri...
