In order to energize the biomedical implantable electronic devices wirelessly for in vivo health monitoring of patients in an isolated, outdoor and inaccessible environment, an alternate driving energy source is highly desirable. In pertinent to this, a photovoltaic driven wireless energizing system has been explored. The system is designed to convert solar energy to a high frequency energy source so as to facilitate energy transfer through resonant inductive link to the automated bio-medical sensing system allied with the receiver unit. The received power is observed to be 286 mW for the coil separation gap of 5 cm and load value of 40 Ω at the resonant frequency of 772.3 kHz. The automated biomedical smart sensor is competent to acquire the body parameter and transmit the consequent telemetry data from the body to the data recording segment. The real-time body temperature parameter of different living beings has been experimented, and to ensure the accuracy of the developed system, the observed parameter has been matched with a calibrated system. The proposed scheme can be suitable for monitoring wirelessly other in vivo health parameters such as blood pressure, bladder pressure, and physiological signals of the patients.
In the current global scenario, one question that arises in every woman's mind is their safety and security. The crime rates against women are increasing at an alarming rate. With the advancement in technology, it is now possible to provide security and self-defense mechanism to women in more than one way. When safety and security are concerned, a smartphone can become a powerful tool to prevent violence against women. Having an app with security features for women, the smartphone tries to help women by sending emergency alerts to chosen people and also lets the police know about victim position and hope nothing goes wrong. Keeping this in mind, an android app named "DEV Ashish" has been developed in Java Development Kit using Android Studio, which is dedicated to providing respite to the relatives in trouble and anxiety. By clicking on a button that is provided on the app, an alert message is sent to the user's emergency contacts. The application shares the user's location with the registered emergency contacts in the form of a message. The application has key features like "alarming as police siren," "fake call," "panic SMS to emergency contacts," "anonymous complaints to five different women safety departments," "offline location sharing to the nearby police station along with IMEI number," etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
