A method for calibrating and/or verifying an implantable detecting device and an implantable detecting device are provided. The method includes: outputting a square wave signal to an implantable detecting device that has been implanted into a subject, where the implantable detecting device is configured to detect a concentration of an analyte in the subject, and a potential of the square wave signal increases incrementally over time; receiving a first current signal produced by the implantable detecting device in response to the square wave signal; generating a calibration curve based on a correspondence between the first current signal and the square wave signal; and performing calibration and/or functional verification on the implantable detecting device based on the calibration curve.

The example of the present application provides a physiological signal sensing method and apparatus, and an electronic device, where an apparatus part includes: one or more light emitters which are used for emitting first light; one or more photoelectric sensors which are used for detecting second light obtained through reflecting the first light via biological tissue and generating a corresponding first signal; a capacitive sensor which is used for detecting changes of a capacitor which is in contact with the biological tissue and generating a corresponding second signal; and a signal processing module which is used for carrying out motion artifact elimination on the first signal according to the second signal, so as to obtain a third signal. In some examples, the one or more photoelectric sensors are multiplexed as the capacitive sensor. Spatial correlation between the first signal and the second signal is higher, and then a better motion artifact elimination effect is achieved.

A method for processing a signal, a method for acquiring data, and an electronic device are provided. The method includes: processing, based on first parameter information stored in a parameter register, an analog signal obtained by sampling a to-be-measured signal to obtain a first digital signal; replacing, when receiving second parameter information sent by a second processing module, the first parameter information in the parameter register with the second parameter information; and processing the analog signal obtained by sampling the to-be-measured signal, based on the second parameter information stored in the parameter register to obtain a second digital signal, and setting a target identifier for a first digital signal of the second digital signal obtained through processing based on the second parameter information.

Embodiments of the present disclosure relate to the field of data processing, and particularly relate to a method for data transmission, a chip, and a storage medium, wherein the method is applied to a target node, and comprises: receiving, in a process of receiving a target data packet, indication data in any one target data set among at least one data set in the target data packet, then determining whether the indication data satisfies a matching condition; updating the target data set in response to the indication data satisfying the matching condition; and normally receiving the target data set in response to the indication data failing to satisfy the matching condition. With this solution, the target node can determine whether to update the target data set simply by caching the indication data, and update, after determining to update the target data set, the target data set in the process of receiving the target data packet, without the need to cache data other than the indication data, so as to quickly and efficiently implement data transmission based on the target node, thereby reducing the data transmission latency based on the target node.

The present disclosure provides a data forwarding method, a physical layer chip, and an electronic device, which can implement high-speed, high-bandwidth, high-precision, and low-delay data transmission, wherein the data forwarding method is used for a physical layer device of sub-node in a transmission network, wherein the network comprises a head node and a plurality of sub-nodes, the head node and the plurality of sub-nodes are connected via a physical transmission medium, and the sub-node further comprises a transmission processing device, receiving, via a first branch of the physical layer device, a first downlink signal transmitted by the head node or a preceding adjacent sub-node among the plurality of sub-nodes through the physical transmission medium; enabling, via the first branch, a second branch of the physical layer device to obtain the first downlink signal through a forwarding module of the physical layer device; and sending, via the second branch, the first downlink signal to a succeeding adjacent sub-node among the plurality of sub-nodes through the physical transmission medium.

Embodiments of the present disclosure relate to the technical field of electronic communication, and provide a method for data transmission, a chip, and a storage medium, wherein the method for data transmission is applied to a target node and comprises: obtaining a first data packet transmitted via a physical layer; and sending, based on a physical transmission medium used to connect a first interface of the target node to a second interface of a downstream node, the first data packet to a physical layer of the downstream node through a physical layer of the target node. With this solution, the first data packet is transmitted in the physical layer, to-be-transmitted data accounts for a large proportion in the first data packet, thereby improving the bandwidth utilization of the target node for data transmission. Moreover, the first data packet is directly transmitted to the downstream node through the physical layer of the target node, without the need for transmission through a switch and without the need for complex encapsulation through a MCU of the target node, thereby reducing the transmission latency in data transmission by the target node, and improving the transmission efficiency.
