Abstract: The present invention provides a transparent and flexible electronic skin with three-dimensional sensing capability. The electronic skin comprises: a substrate; an transparent and flexible electric field sensor disposed on the substrate; a control circuit disposed on the substrate; and a transparent and flexible protective layer encapsulating the electric field sensor and the control circuit. The electric field sensor includes a transmitter electrode; one or more receiver electrodes; and dielectric layer arranged between the transmitter electrode and receiver electrodes. The control circuit is connected to the electric field sensor and configured to: drive the transmitter electrode to transmit a reference signal to establish a quasi-static electrical near field; and process one or more measurement signals received by the one or more receiver electrodes respectively, each measurement signal is indicative of a distortion of the quasi-static electrical near field due to proximity of an object.

Abstract: A portable blood pressure sensor comprises a sensing device, a force generation device, a first processor, a first flexible layer, and a second flexible layer. The sensing device comprises a first piezoelectric layer, and a second piezoelectric layer. The force generation device provides back pressure to the first and second piezoelectric layers. The first processor is electrically connected to the sensing device and the force generation device. The second flexible layer encapsulates the sensing device, the force generation device, and the first processor on the first flexible layer.

Abstract: The present disclosure is directed to a method, apparatus and computer medium for switching a user terminal, and an access point. The method may be performed by an access point capable of operating in at least a first band and a second band, and comprises the following steps: in response to determining that a user terminal being in the first band of the access point satisfies a condition for inter-band switching, measuring a communication performance of the user terminal in the first band as a first metric; after the user terminal is switched from the first band to the second band of the access point, measuring a communication performance of the user terminal in the second band as a second metric; and causing the user terminal to be in the band associated with a better one of the first metric and the second metric.
