This paper reports the development, evaluation and validation of DosiTag, a dosimetric platform based on Near Field Communication (NFC) technology. The designed system comprises two main parts: passive NFC sensing tag as dosimeter unit, which includes commercial P-channel MOSFET transistor radiation sensor; an NFC-enabled smartphone running custom-developed application reader unit. Additionally, cloud service messaging protocol Message Queue Telemetry Transport (MQTT) has been implemented...
Purpose The response to radiation typically used in radiotherapy treatments has been experimentally evaluated for three samples of two phototransistors (BPW85B and OP505A) PIN photodiodes types (VTB8440BH BPW34S). Methods To that end, a staggered irradiation cycle applied which included dose rate values from 0.81 4.87 cGy/s, achieving total absorbed 21.4 Gy. have irradiated with linear accelerator the relations between induced photocurrent average instantaneous rates, accumulated charge...
The use of facemasks by the general population is recommended worldwide to prevent spread SARS-CoV-2. Despite evidence in favour reduce community transmission, there also agreement on potential adverse effects their prolonged usage, mainly caused CO
In this work we present a full-passive flexible multigas sensing tag for the determination of oxygen, carbon dioxide, ammonia, and relative humidity readable by smartphone. This is based on near field communication (NFC) technology energy harvesting data transmission to The gas sensors show an optic response that read through high-resolution digital color detectors. A white LED used as common optical excitation source all sensors. Only reduced electronics with very low power consumption...
This work presents an innovative approach employing passive Radiofrequency Identification (RFID) technology to develop a comprehensive ballistocardiography (BCG) system for contactless and non-invasive vital sign monitoring of individuals on mattress. The method relies wireless energy transfer through inductive coupling at 13.56 MHz between active powering board passive, flexible sensing with dimensions 12.6 × 4.7 cm2. Both boards face each other separation distance 3 cm. demonstrates...
