Sensor devices including dissolvable tissue-piercing tips are provided. The sensor devices can be used in conjunction with dissolvable needles configured for inserting the sensor devices into a host. Hardening agents for strengthening membranes on sensor devices are also provided. Methods of using and fabricating sensor devices are also provided.

An apparatus that includes a partial power source including a first material and a second material, the partial power source configured to generate, upon contact with a conducting medium, a potential difference between the first material and the second material to provide power to a control device, and generate, using the first material and the second material, a current flow within the conducting medium, the current flow including information encoded based on a variable conductance between the first material and the second material.

A body fluid analyte detection device, includes: a transmitter, provided with at least one first clamping part; a bottom shell, provided with a second clamping part corresponding to the first clamping part, the transmitter being assembled on the bottom shell by mutual snap fitting of the first clamping part and the second clamping part, the bottom shell including a fixing part and a force application part, and the fixing part being fixed and applying a force to the force application part in a direction to disable the bottom shell, so that the first clamping part and the second clamping part are separated from each other, and then the bottom shell and the transmitter are separated; a battery, used for supplying power to the transmitter; a sensor, used for detecting body fluid analyte parameter information and electrically connected to the transmitter to transmit a parameter signal.

A body fluid analyte detection apparatus is provided. Applying a force to a force applying portion of a bottom case in one direction can make the bottom case fail, and then separate the bottom case and a transmitter from each other. Before the bottom case is mounted to a human body, the bottom case is fixed together with a mounting unit by means of a snap-fit portion. Operation steps of a user when separating the bottom case from the transmitter are reduced, and the failure rate of the bottom case before being mounted to the human body is also reduced, thereby improving the user experience, and enhancing the reliability of the body fluid analyte detection apparatus.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Embodiments described herein include a device and a non-transitory computer-readable medium. The device includes one or more processors, an analyte sensor, a communication module, and memories. The processors are configured to generate analyte data indicative of a monitored analyte level measured by the analyte sensor corresponding to a first time, generate analyte data indicative of the monitored analyte level measured by the analyte sensor corresponding to a second time, calculate a correction parameter based on the analyte data corresponding to the analyte data corresponding to the first time and analyte data corresponding to the second time, and perform a lag correction to obtain the monitored analyte level using at least the calculated correction parameter. The calculated correction parameter comprises a lag time determined from the analyte data. The performed lag correction comprises a linear correction model based on the calculated correction parameter.
