This Arduino project lets you see your heartbeat
— April 16th, 2020
It’s easy enough to check your heart rate, but Sharath Naik has designed a project that actually lets you see it instead. The roughly heart-shaped, 3D-printed device sits on a pedestal with four sections that are pushed out in response to your pulse.
The visualizer utilizes a servo and linkage system to physically actuate beating, and a MAX30100 pulse oximeter mounted to the base is implemented to track your heartbeat. This data is fed into an Arduino Nano board, which signals the SG90 servo to expand and contract the model in response to your own body.
More info and code are available in Naik’s post, and you can see it in action below!

The difference between the functions of isolation clothing and Disposable Protective Clothing:
(1) Different definitions:
Isolated gown: It is a protective equipment used by medical staff to protect them from infection by blood, body fluids and other infectious substances.
Protective Clothing: disposable protective equipment worn by medical staff when they come into contact with patients with Class A or Class A infectious diseases.
(2) Different uses: isolation clothing is used in the isolation area, that is, in the hospital, and protective clothing is used in the CDC.
(3), there are differences for patients:
Wear a gown: contact patients with infectious diseases transmitted by contact, such as patients with disease-transmitted diseases and patients with multi-drug resistant bacteria; implement protective isolation for patients, such as patients with extensive burns and patients with bone transplantation; Infected when blood, body fluids, secretions, feces are sprayed. In short, the isolation gown is used for patients with strict isolation, contact isolation and protective isolation.
Wear protective clothing: when exposed to airborne and droplet-borne infectious disease patients, may be splashed by the patient’s blood, body fluids, secretions, and feces. But this patient is not very serious but just a general infection.
(4). The material is different: protective clothing is a one-time-use item, while isolation clothing is not.
