Transient electronics is an increasingly significant area of research developing devices that work until exposure to light, heat or liquid cause them to degrade. Back in 2012 we wrote about transient electronics that dissolve in a patient’s body. Now, Iowa State University scientists have developed a transient battery that is the first of its kind, and able to demonstrate a reasonable amount of stability as well as power. The device is a self-destructing, lithium-ion battery capable of delivering 2.5 volts of power and dissolving or dissipating in 30 minutes when dropped in water. Scientists involved in the research explains that…
