Wearable Thermal Sensors for Subdermal Fluid Monitoring
Summary
The USPTO published patent application US20260091172A1 by Rhaeos Inc. disclosing a wearable thermal sensor system for monitoring subdermal fluid levels. The system includes at least six temperature sensors, three thermal actuators, a flexible substrate, and a microprocessor configured to trigger alerts based on calculated alert conditions from temperature readings.
What changed
The USPTO published patent application US20260091172A1 on April 2, 2026, disclosing Rhaeos Inc.'s wearable thermal sensor system for subdermal fluid monitoring. The system comprises at least six temperature sensors, at least three thermal actuators on a flexible substrate, an adhesive layer, power source, memory storage, and a microprocessor. The microprocessor activates thermal actuators to heat subdermal fluid, receives temperature information from sensors, and triggers alerts when calculated alert conditions are met. Application No. 19346363 was filed September 30, 2025.
Patent application publications do not create immediate compliance obligations. Companies developing wearable health monitoring devices should review the disclosed claims to assess potential patent landscape implications and freedom-to-operate considerations for their own product development activities.

Abstract
Systems and methods for monitoring subdermal fluid are disclosed. The subdermal fluid monitoring system may include a flexible substrate, at least six temperature sensors and at least three thermal actuators supported by the flexible substrate, an adhesive substrate, a power source configured to supply power to the at least six temperature sensors and to the at least three thermal actuators; a memory storage device; and a microprocessor in communication with the memory storage device. The microprocessor may be configured to activate the power source to supply power to at least one thermal actuator to cause heating of a subdermal fluid, receive information associated with a temperature of the subdermal fluid from at least one temperature sensor; calculate an alert condition based on a set of instructions received from a memory storage device and the temperature of the subdermal fluid; and trigger an alert if the alert condition is met.
