The invention provides a symmetrical clamped micro-beam electric power sensing device based on MEMS resonators, and belongs to the technical field of MEMS sensing. The sensing device comprises a sensing assembly. The sensing assembly comprises a vibration beam, an excitation electrode, a tuning electrode and an auxiliary electrode. The two ends of the vibration beam in the axial direction of the vibration beam are connected with the auxiliary electrodes, and the exciting electrodes and the tuning electrodes are arranged at intervals in the length direction of the vibration beam and arranged on the same side of the vibration beam. Excitation voltage is applied to the excitation electrode so that the excitation electrode can excite the vibration beam to generate resonance. Tuning voltage is applied to the tuning electrode so that the tuning electrode can adjust the rigidity of the vibration beam according to the environment temperature, and the thermal power corresponding to the heat source can be inverted. The two sensing assemblies are arranged in a central symmetry mode, so that interference of electrostatic fields generated by the excitation electrodes and the tuning electrodes corresponding to different vibration beams can be weakened mutually. According to the invention, high-precision power inversion in a wide temperature range can be realized.

This invention discloses an electrolytic cell electrode with an integrated in-situ perturbation device and its preparation method. The electrolytic cell electrode includes a substrate layer, an electro-actuated perturbation layer disposed above the substrate layer, and a catalytic wetting layer disposed above the electro-actuated perturbation layer. The electro-actuated perturbation layer is composed of several electrostrictive microbeams, which are fixed to the substrate layer and do not cover the pores in the substrate layer. Each electrostrictive microbeam consists of a fixed part and a driving part connected to the fixed part. The fixed part is used to fix the microbeams to the substrate layer, while the driving part is suspended above the substrate layer and vibrates under the action of a pulsed current, with the vibration direction perpendicular to the plane of the substrate layer. This invention integrates the electro-actuated microbeam array with the electrode body, eliminating the need for an external drive. This saves space and avoids problems such as energy consumption, sealing failure, and leakage short circuits caused by separate designs, making it suitable for high-density, miniaturized electrolysis systems.

A radiotherapy system is configured to receive an open-field X-ray beam from a superficial radiotherapy machine and direct the beam through a grid module configured to spatially fractionate the open-field beam into a group of spaced-apart microbeams. A patient applicator defines an enclosed space having a patient support surface for supporting a target body part. A beam receiver of the patient applicator receives the group of microbeams directed at the target body part on the support surface. The enclosed space is defined by a wall structure comprising shielding sufficient to absorb the radiation emitted by the superficial radiotherapy machine. The patient applicator can be portable, and the superficial radiotherapy machine can be wheeled.

This invention belongs to the field of aerospace electronic device reliability testing technology, and particularly relates to a proton microbeam single-event effect testing system and an error rate assessment method. The system includes a common reference positioning fixture, a pulsed laser single-event test module, and a proton microbeam single-event effect test module. A unified absolute coordinate system is established through an optical positioning structure on the fixture, achieving precise alignment of the pulsed laser platform and the proton microbeam platform. The method involves first fixing the pre-processed device under test (DUT) to the fixture, then scanning the sensitive area and acquiring the error section on the pulsed laser platform, and finally transferring it to the proton microbeam platform to reproduce the coordinates and perform point-to-point irradiation of the sensitive area. The on-orbit error rate is then assessed based on the irradiation response data. This invention solves problems such as the difficulty in selecting proton microbeam test parameters, insufficient cross-platform positioning accuracy, and the lack of multi-functional chip partition testing, enabling efficient sensitive area positioning, precise irradiation, and on-orbit reliability assessment.
