A method is provided which includes providing a sensor operable to measure movement over time on a user. The sensor includes an alert unit. The sensor is configured with a threshold to activate the alert unit when the measured movement over time is below the threshold. The measurements of movement over time are obtained, and it is determined whether the measured movement over time is below the threshold. When the measured movement is below the threshold, the alert unit at the sensor is activated to alert the user.

A patient fluid absorption and estimation device includes an absorbent layer comprising an absorbent material and adapted to absorb fluids. The device's sensing layer includes piezoresistive element(s). The sensing layer abuts the absorbent layer such that changes in at the mass or shape of the absorbent layer cause a change in the strain in the piezoresistive element(s). The device includes memory and processing in communication with the memory. The processing includes a piezoresistive element interface. The processing senses a voltage, representing an estimation of the amount of fluid absorbed, across each element via the interface. The processing then converts each voltage to a digital value, and stores the value in the memory. The device includes wireless communications that receives commands from an external computer system to transmit the values, and transmits the values to the external. A power subsystem powers each subsystem.

Disclosed embodiments relate to apparatuses and methods for a skin perfusion pressure determination device. In some embodiments, a skin perfusion pressure determination device can include a sensor module having a first sensor for sensing a first parameter associated with a pressure exerted on a target area by the sensor module and a second sensor for sensing a second parameter associated with an amount of blood perfusion at the target area. In some embodiments, the first sensor and the second sensor can be arranged such that, when the sensor module is pressed against the target area the first sensor produces an output corresponding to the sensed first parameter and the second sensor produces an output corresponding to the sensed second parameter.
