Near-infrared (NIR) small-molecule acceptors that absorb at wavelengths of up to 1000 nm are attractive for applications in organic photodetectors (OPDs) and biometrics. In this study, we incorporated IEICO-4F as the third component for PffBT4T-2OD:PC 71 BM-based OPDs to provide an efficient NIR response while greatly suppressing the leakage current at reverse bias. By varying the blend ratio and thickness (250−600 nm), we obtained an NIR OPD displaying an ultralow dark-current density (J D = 2.62 nA cm −2 ), ultrahigh detectivity [D* = 7.2 × 10 12 Jones (850 nm)], high sensitivity, and photoresponsivity covering the region from the ultraviolet to the NIR. We used tapping-mode atomic force microscopy, optical microscopy, grazing-incidence wide-angle X-ray scattering, and contact angle measurements to investigate the effect of IEICO-4F on the performance of the ternary OPDs. The low compatibility of PffBT4T-2OD and IEICO-4F, originating from weak intermolecular interactions, allowed us to manipulate the degree of phase separation between the donor and acceptor in the ternary blends, leading to an optimized blend morphology featuring efficient charge separation, transport, and collection. To demonstrate its applicability, we integrated our OPD with two light-emitting diodes and used the system for precisely calculated transmissive pulse oximetry.

“…Like glucose, monitoring heart rates can be challenging, even for patients in healthcare facilities. Periodic heart rate checks don't guard against rapid fluctuations in heart rates, and conventional devices for continuous cardiac monitoring used in hospitals require patients to be attached to wired machines constantly, impairing their mobility [22]. Today, a variety of small IoT devices are available for heart rate monitoring, freeing patients to move around as they like while ensuring that their hearts are monitored continuously.…”

The role of Internet of Things (IoT) technology continues to increase in various fields, especially health. IoT can connect doctors with their patients via the Internet. Portable IoT-based health monitoring devices can significantly reduce the distance between patients and doctors. The important influence of IoT technology in the health sector can be seen from its efficiency and important role in developing and improving the quality of health services. IoT is the last Internet revolution that allows integrity between machines and objects. Developers and users still have to pay attention to data security, considering that medical history is a matter of privacy for some people. Blockchain technology has been predicted by the industry and research community as a secure, fast, reliable and transparent solution for IoT-based systems. Most blockchain technology is used for data management operations in the IoT-based health sector, which improves data security, including data integrity, access control, and maintenance of privacy.

“…Melalui pemaparan tersebut dapat diketahui behwa kesalahan dalam tahap pra analitik, terutama pengambilan sampel memberikan dampak yang cukup besar terhadap hasil pemeriksaan laboratorium dan tingkat kenyamanan dari pasien. Tentu hal ini tidak sesuai dengan poin ke 3 dari SDGs (Sustainable Development Goals) yaitu 'Kehidupan Sehat dan Sejahtera' pada masyarakat [6] [7]. Pada poin ini tidak dapat terlaksana secara maksimal apabila ketika pada proses diagnosa penyakit yang dilakukan di laboratorium terdapat kesalahan sehingga menyebabkan salah treatment atau pemberian obat terhadap pasien.…”

Dewasa ini telah ditetapkan standar operasional prosedur untuk praktik venipuncture. Phlebotomyst yang melakukan tindakan tersebut harus memberi suatu alat pada area bawah siku pasien sebelum melakukan tindakan venipuncture. Fungsi alat ini salah satunya untuk memberikan kenyamanan pada pasien serta memudahkan akses flebotomis mencari pembuluh darah vena. Fakta di lapangan menunjukkan belum ada suatu alat fungsional yang khusus digunakan untuk phlebotomyst melakukan pengambilan darah vena secara efektif dan efisien. Alat yang biasa digunakan oleh phlebotomyst dapat berupa benda-benda apa saja yang difungsikan untuk meluruskan tangan pasien dan terkadang menggunakan benda-benda seadanya yang dapat menimbulkan ketidaknyamanan, kecemasan, menyebabkan terjadinya hematom dan media untuk menularkan penyakit serta kualitas dari sampel yang kurang baik. Tujuan dari penlitian ini adalah untuk membuat suatu alat yang dapat digunakan untuk memberikan kenyamanan pada pasien, serta mengurangi risiko terjadinya hematom (pecahnya pembuluh darah) saat dilakukan tindakan venepuncture. Pada penelitian ini, kursi phlebotomy berbasis IoT telah berhasil dibuat menggunakan Node MCU tsp 8266 serta linier actuator hidrolik. Bagian lengan pada kursi tersebut diberikan bantalan yang lembut serta dapat diatur ketingggiannya sesuai dengan kenyamanan tangan pasien. Pengaturan ketinggian dapat dilakukan secara otomatis menggunakan smartphone. Dengan adanya alat ini diharapkan pengambilan sampel darah pasien lebih efisen, efektif, serta memenuhi syarat dan standar, sehingga pasien merasa puas terhadap pelayanan laboratorium yang diberikan.
