可穿戴电子设备是持续、长期和远程健康监测的重要趋势。然而,大多数现有的可穿戴电子设备只能感知皮肤表面或皮肤表面以下 1 厘米的浅层组织的信号。然而,在深层组织中,即皮肤表面下 1 厘米以上的组织中,有更多的事件发生。通常,这些深层组织信号与疾病状态和进展的相关性比表面信号更强、更快。现有的可穿戴电子设备只能捕捉到冰山一角。皮肤下还有很大的空间。
加利福尼亚大学圣迭戈分校的 Sheng Xu 团队通过开发一种可穿戴的超声波贴片,重塑了超声波诊断。该贴片由超声换能器阵列、背衬层和匹配层组成,通过可拉伸金属丝相互连接,并封装在弹性体中。该贴片与人体皮肤一样顺滑,可连续佩戴 24 小时以上,且不会对皮肤造成任何刺激。已将可穿戴超声波贴片用于监测许多现有可穿戴设备无法监测到的深层组织信号。
