"Since the first pacemaker was implanted in 1958, bioelectronic devices have benefited millions of patients, restoring hearing, reducing pain, and alleviating depression. Surprisingly, devices have remained about the same size, largely because of the bulkiness of the battery. Scientists now envision that tiny sensors and stimulators might be used to help treat intractable diseases like cancer and diabetes. My work seeks to make this vision a reality through new wireless technologies. By enabling smaller and deeper bioelectronic devices, these technologies could bring closer the day where doctors will, instead of a pill, prescribe a tiny, wireless device."
