A research team has developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room temperature, preventing accidental needle stick injuries and unethical multiple use of needle. A thin-film temperature sensor can be embedded with this needle, enabling real-time monitoring of the patient’s core body temperature, or detection of unintended fluid leakage, during IV medication.
