Sensors made of graphene and plasticine monitor blood pressure in real time over a 24-hour period. Just add a little graphene, you can turn the plasticine into a pressure sensor. This sensor is extremely sensitive, not only to monitor the pulse of the body, and even to explore the footsteps of a small spider. This graphene plasticine is called "G-putty," and developers hope it will develop devices that continuously monitor blood pressure. In addition G-putty also showed the ability to self-repair, indicating that it may become more intelligent graphene composites. Since graphene was first isolated in 2004, researchers have attempted to add these thin layers of carbon atoms to a variety of materials in the hope of creating composites that benefit from the high strength and excellent conductivity of graphene. Surprisingly, however, few have attempted to mix graphene with such viscoelastic materials as plasticine. The plasticine exhibits both elastic solid and liquid characteristics, such as putting a plasticine on a hole that slowly leaks past. Conor Boland, a researcher at the Jonathan Coleman Nanotechnology Laboratory at Dublin's Trinity College Dublin, said he was curious what would happen if graphene was mixed with plasticine. "I'd love to say that the idea was conceived, but not," Coleman said with a smile: "Because we happen to have a tradition of using household appliances for scientific research." (His team was at In 2014, it was discovered that graphene can be obtained by rapidly stirring the graphite with a stirrer in the kitchen.)

Silicone sealing strip is a sealing product mainly made of silicone. The following is a detailed introduction about it:
Material characteristics:
Excellent high and low temperature resistance: It can be used for a long time in the temperature range of -60 ℃ to 250 ℃, and can still maintain good elasticity and sealing performance in low temperature environments. It is not easy to deform or soften in high temperature environments, and is suitable for sealing various extreme temperature conditions, such as ovens, refrigerators, high-temperature pipelines and other equipment.
Excellent weather resistance: It has good UV resistance, ozone resistance, and anti-aging performance. When exposed to outdoor or complex climate for a long time, its physical properties have only slight changes and its service life is long.
Good chemical stability: It has good resistance to various chemical substances such as acids, bases, and salts, and is not easily corroded by chemical substances. It can be applied in sealing fields with corrosive environments such as chemical engineering.
Physiological inertness and safety: Silicone itself is non-toxic, odorless, and non irritating to the human body. It is widely used in the medical field to make medical catheters, drainage tubes, etc. It is also safe and reliable when in contact with food in daily life.
High elasticity and resilience: It can quickly recover to its original state after being squeezed or stretched by external forces, ensuring good sealing effect, and is not prone to permanent deformation during long-term use.
Product advantages:
Excellent sealing performance: The material of the silicone dense strip is tight, which can effectively fill various gaps, prevent the passage of gases, liquids, dust and other substances, and play a good sealing role.
Easy to process and shape: It can be processed into various shapes and sizes according to different usage requirements, such as D-type, P-type, E-type, circular, square, etc., to meet the installation requirements of different scenarios.
Adhesive backing function: Some silicone dense strips come with adhesive backing, making it easy to stick and install. They can tightly adhere to various smooth surfaces with long-lasting adhesion and are not easy to peel off.
Environmentally friendly and pollution-free: No harmful substances are produced during the production process, and the waste can be naturally degraded, making it environmentally friendly.
Application areas:
Construction industry: used for sealing doors, windows, and curtain walls, which can improve the insulation, thermal insulation, waterproofing, and windproof performance of buildings; It can also provide good sealing and buffering in areas such as building deformation joints and pipeline interfaces.
Automotive industry: applied to the sealing of doors, windows, engine compartments, luggage compartments, and other parts of automobiles, with the effects of shock absorption, waterproofing, dust prevention, and sound insulation; It can also be used for fixing and protecting automotive components.
Electronic and electrical industry: As a sealing and insulation material for electronic equipment, such as the enclosure sealing of televisions, oscilloscopes, potentiometers, and insulation protection for wires and cables.
Medical device industry: used to manufacture seals, catheters, drainage tubes, etc. for medical equipment, meeting the hygiene and safety requirements of the medical industry.
Household goods industry: can be used for sealing and decorating kitchen utensils, bathroom equipment, furniture, etc., such as sealing oven doors, refrigerator doors, faucets, etc.
