“…Liquid level data is transmitted wirelessly from the microcontroller to the IoT cloud, the mobile application, and to the medical staff mobile phones. The use of a wireless flexible capacitive sensor to detect fluid levels in the IV bag by changing the capacitance when the fluid level in the bag decreases is shown in [23]. The sensor communicates wirelessly with a microcontroller that produces an alarm at the appropriate time.…”

Intravenous (IV) infusion therapy allows the infusion fluid to be inserted directly into the patient’s vein. It is used to place medications directly into the bloodstream or for blood transfusions. The probability that a hospitalized patient will receive some kind of infusion therapy, intravenously, is 60–80%. The paper presents a smart IV infusion dosing system for detection, signaling, and monitoring of liquid in an IV bottle at a remote location. It consists of (i) the sensing and computation layer—a system for detection and signaling of fluid levels in the IV bottle and a system for regulation and closing of infusion flow, (ii) the communication layer—a wireless exchange of information between the hardware part of the system and the client, and (iii) the user layer—monitoring and visualization of IV therapy reception at a remote location in real time. All layers are modular, allowing upgrades of the entire system. The proposed system alerts medical staff to continuous and timely changes of IV bottles, which can have positive effects on increasing the success of IV therapy, especially in oncology patients. The prescribed drip time of IV chemotherapy for the full effect of cytostatics should be imperative.

“…Particularly, the camera-based solutions [22] capture the image of liquid, and count droplets or estimate the liquid height by image processing. The capacitive-sensor-based approaches [19,29] deploy the capacitive sensor around the drip chamber, and leverage the capacitance change caused by falling droplets to estimate the drip rate. The photoelectric-sensor-based approaches [4,8,9,20,23,30] set a pair of light transmitter and receiver around the drip chamber, and leverage the block of light caused by falling droplets to estimate the drip rate.…”

As an important indicator of the infusion monitoring for clinical treatment, the drip rate is expected to be monitored in an accurate and real-time manner. However, state-of-the-art drip rate monitoring schemes either suffer from high maintenance or incur high hardware cost. In this paper, we propose DropMonitor, an RFID-based approach to perform the mm-level sensing for infusion drip rate monitoring. By attaching a pair of batteryless RFID tags on the drip chamber, we can estimate the drip rate by capturing the RF-signals reflected from the vibrating liquid surface caused by the falling droplets. Particularly, we use the sensing tag to perceive the liquid surface vibration in the drip chamber and further derive the drip rate for infusion monitoring. Moreover, to sufficiently mitigate the multi-path interference from the surrounding human activities, we use the reference tag to perceive the multi-path signals from the indoor environment. By computing the difference of RF-signals from tag pairs, we cancel the multi-path interference and extract the drip-rate-related signals. We have implemented a prototype system and evaluated its performance in real applications. The experiment results show that DropMonitor can accurately estimate the infusion drip rate, and the average relative error of drip rate estimation is below 1% for conventional cases. In this way, considering the essential sampling rates of each tag, DropMonitor is able to monitor the drip rate for over a dozen of infusion bottles/bags in parallel with one COTS RFID system.

“…[ 26 ] Printed flexible devices such as gas, temperature, strain and magnetic sensors have gained remarkable attention due to their noteworthy applications in soft robotics, [ 27,28 ] electronic skins, [ 20 ] wearable electronics, [ 29 ] smart textiles, [ 30 ] contactless human–machine interfaces and future bio‐integrated consumer electronics [ 11 ] . The versatility of printed flexible devices is enabled due to an integrability with different surface geometries which is promising for a range of applications such as liquid level monitors [ 31 ] and flexible position sensors.

Till now application of printed magnetoelectronics is hindered by lack of large area exchange coupled metallic multilayers required to produce printable magneto‐sensory inks. Large‐scale roll‐to‐roll (R2R) fabrication process is an attractive approach owing to its capabilities for high volume, high throughput, and large area manufacturing. Precise and high performance R2R sputtering technology is developed to fabricate large area giant magnetoresistive (GMR) thin‐films stacks that contain 30 metallic bilayers prepared by continuous R2R sputtering of Co and Cu sequential on a hundred meters long polyethylene terephthalate (PET) web. The R2R sputtered Co/Cu multilayer on a 0.2 × 100 m2 PET web exhibits a GMR ratio of ≈40% achieving the largest area exchange coupled room temperature magneto‐sensitive system demonstrated to date. The prepared GMR thin‐film is converted to magnetosensitive ink that enables printing of magnetic sensors with high performance in a cost‐efficient way, which promotes integration with printed electronics. An average GMR ratio of ≈18% is obtained for 370 printed magnetic sensors. The realized precise R2R sputtering approach can also be extended to a wide range of hybrid thin‐film material systems opening up a path for new functional inks applied with printing technologies.
